WELDING PROCEDURES

Out-Of-Position Welding (Vertical and Overhead)

When welding out-of-position, the molten metal tends to spill out
of the joint. To offset this tendency, an electrode with a fast
freezing deposit is needed.

Welding made with out-of-position electrodes is slow, relatively
expensive and require a high degree of operator skill. Therefore,
whenever possible, work should be positioned for downhand
welding using High-Deposition electrodes – see pages 8-15.

Vertical, overhead, and horizontal groove welds on plate thicker
than 1/2” are most economically done with low hydrogen
electrodes – see pages 24-34.

ertical Up vs. Vertical Down

V

Vertical down is recommended for fastest welding of 18 gauge
to 3/16” thick steel. A description of the recommended drag
technique along with sheet metal procedures are given in the
section High-Speed Welding on pages 18-23.

Vertical up techniques provide deeper penetration and lower
overall welding costs on plate over 3/16” thick.

ode, Current and Polarity

Electr

The vertical up and overhead procedures in this section
recommend 3/16” and smaller Fleetweld 5P or 5P+ (E6010)
electrode using electrode positive and currents in the lower
portion of the electrode’s range. When only AC otuput is
available, use Fleetweld 35 or Fleetweld 180 (E6011) electrode at
about 10% higher current.

1. Make first pass root beads with a whipping technique. Whip

time to let the crater cool before returning the electrode tip to
the crater area to add more weld metal.

is often needed for the second pass
to assure good fusion along the edge of the first bead. The
box weave is similar to the straight weave except a slight
upward motion is made at both sides of the weld. Maintain a
short arc with no whipping.

3. Employ a straight weave

for the final passes. Simply move
the electrode tip back and forth across the surface of the
weld pausing slightly at both edges to insure penetration and
wash-in without undercut.

Overhead Techniques

Weld overhead as a series of root beads using a slight
circulation motion in the crater sometimes accompanied by a
whip. Weave beads are too fluid and will spill

High-Deposition Welding

High deposition applications includes groove, fillet, lap and
corner welds in 3/16” and thicker plate welded with the work
level or slightly downhill. These joints are capable of holding a
large molten pool of weld metal as it freezes.

These welds are made with Jetweld electrodes because the high
iron powder content in the coating produces high deposit rates
to fill joints in the shortest time for economical welding.

When desired, the following alternate electrodes can be used
with similar procedures:

Jetweld Operating T

Polarity and Current – Use AC for fast welding speeds, high
deposit rates, and good arc characteristics. DC can be used but
the resulting arc blow may complicate control of the molten
puddle.

Optimum current for most jobs is 5-10 amps above the center of
the electrodes range. Do not exceed the center of the range for
x-ray quality deposits.

Use a Drag Technique – Tip the electrode 10 to 30° in the direc­tion of travel and make stringer beads. Weld with the electrode
end lightly dragging on the work to force the molten metal out
from under the electrode tip allowing adequate penetration. The
smooth welds look almost like automatic welds.

Travel fast, but not too fast for good slag coverage. Stay about
1/4” to 3/8” ahead of the molten slag. If travel speed is too slow,
a small ball of molten slag may form and roll ahead of the arc
causing erratic bead shape, spatter, and poor penetration.

Deep Groove Groove Welds – To hold the large pool of molten
weld metal from Jetweld electrodes, either a weld backing plate
or a root pass made with deep penetrating electrode (usually
E6010 or E6011) is required. Deposit Jetweld beads with a
stringer technique or a slight weave to obtain fusion to both
plates. Split weave welds are better than a wide weave near the
top of deep grooves. Size the second to last layer so the last
layer will not exceed a 1/16” buildup.

and a flat or slightly convex bead. Excess convexity wastes weld
metal. A concave bead is susceptible to shrinkage cracks.

Flat fillet and lap welds are made with the same general
techniques as groove welds.

Weld single pass fillets using a drag technique with the tip of the
electrode touching both plates. Usually weld with the electrode
at a 45° angle (end view) from the horizontal plate. However,
adjust this angle from as little as 30° to as much as 60° when
required to maintain equal leg sizes on both plates.

When two passes are needed, deposit the first bead mostly on
the bottom plate. To weld the second pass hold the electrode at
about 45° angle fusing into the vertical plate and the first bead.

Make multiple pass horizontal fillets as shown in the sketch. Put
the first bead in the corner with fairly high current even though
there may be slight undercut, succeeding passes will burn it out.
Deposit the second bead on the horizontal plate fusing into the
first bead. Hold the electrode angle needed to deposit the filter
beads as shown, putting the final bead against the vertical plate.

Welding Inclined Plate

L

These procedures are used when:

1. The work cannot be positioned in the level position
for high speed welding with High Deposition
Jetweld electrodes.

2. The weld is made partly in the level position and
partly downhill.

Fleetweld 47 electrodes have a fairly high iron powder content in
the coating, which provides a good deposition rate consistent
with downhill welding ability.

Using a drag technique, maintain about a 5/32” distance
between the end of the electrode and the molten slag. If the
distance is too great, skips occur in the weld. If the distance is
too short, the slag will flow under the arc causing slag holes.

Generally, use the highest current possible that will not burn­through, undercut, or melt the edges of lap, corner, or edge
welds. Fast welding depends upon the operators skill at
staying on the joint and traveling at a uniform speed. A few
days practice may be needed by good welders when first
starting sheet metal welding.

For maximum welding speed, minimum distortion and flat welds
generally position joints for welding 45° to 75° downhill.

The procedure tables assume tight fit-up and adequate
clamping or tacking for fast travel speeds and minimum
distortion. Use copper backing whenever possible to decrease
burnthrough tendencies. When poor fit-up is encountered:

1. Reduce the current.

2. Increase the drag angle.

3. With E6010 or E6011 electrodes use a quick whip
technique with a slight circular motion in the crater to
bridge the gap.

4. With E6012 or E6013 electrodes, use a small quick
weave technique to bridge the gap.

-18-

When welding with High Speed electrodes (E6012 and E6013)
deposit the entire weld in one pass using non-weave beads or a
slight weave. Drag the electrode on the joint and stay ahead of
the molten pool. Use enough drag angle so the arc force pushes
the weld metal back. Use currents in the high portion of the elec­trode’s range.

When welding with Out-Of-Position electrodes (E6010 and
E6011), deposit the entire weld in one pass using non-weave
beads or a slight weave. Hold a 1/8” or shorter arc. Move as
fast as possible while maintaining good fusion. Use currents in
the middle of the electrode’s range.

Weld overhead joints using E6010 or E6011 electrodes with a
whip technique and a slight circular motion in the crater. Do not
weave. Point the electrode directly into the joint and slightly for­ward into the direction of travel. Use a fairly short arc and travel
fast enough to avoid spilling. Use currents in the lower portion
of the electrode’s range. Overhead welding of 18 gauge and
thinner is not recommended.

Employ the same techniques for this High-Deposition electrode
as recommended for E7024 electrodes. Clean the slag from
every bead on multiple pass welds to prevent slag inclusions
which would appear on X-ray inspection.

EXX18 W

elding Techniques

Procedures and techniques for E7018 electrodes can be used
for E8018, E9018, or E11018 Lincoln electrodes.

Polarity - Whenever possible use electrode positive for 5/32” and
smaller electrodes. AC can be used at about 10% higher currents.

Use AC on 3/16” and larger diameter electrodes to minimize arc
blow for best operating characteristics. DC+ can also be used
at about 10% lower currents.

Drag the electrode lightly. Since low hydrogen electrodes rely on

the molten slag for shielding, never hold a long arc, whip, leave
the crater, or move rapidly in any direction. Failure to follow
these techniques may result in porosity and/or reduce mechani­cal properties.

For Clean Tie-Ins – Strike the arc ahead of the crater, move
quickly back into the crater, then proceed in the direction of
welding. This technique welds over the striking area, eliminating
porosity or tendency for poor starting bead shape.

Multiple Pass Welds – Clean the slag after each bead. When
welding in the downhand position, use stringer beads or small
weaves rather than wide weaves to avoid slag inclusions.

ertical Techniques

V

Use 5/32” or smaller electrodes and currents in the lower portion
of the electrode’s range. Techniques are as follows:

1. Use a triangular weave for heavy single pass welds.

Multipass

2. For multipass welds, deposit a first pass bead using a slight

weave. We emphasize the importance of moving into the
corner to assure penetration into the corner. Weld additional
layers with a side-to-side weave hesitating at the sides long
enough to melt out any small slag pockets and minimize
undercut. Travel slow enough to maintain the shelf without
spilling weld metal.

3. With this technique, slag spills down the weld. As long as no
metal spills, operation is normal. Once welders are familiar
with the EXX18 techniques, they will quickly learn to make
sound welds of excellent appearance.

Horizontal Gr

oove and Overhead Weld Techniques

Weld with a series of first pass beads using a slight circular
motion in the crater. Do not whip. Use 5/32” or smaller
electrodes and currents in the lower portion of the

Continued

For stick electrode welding only

Based on AWS Specification D1.1

Notes

(1) Welding shall not be done when ambient temp. is lower than 0ºF.

Parts on which metal is being deposited shall be at or above the
specified temperature for a distance equal to the thickness of the part
being welded, but not less than 3”, in all directions from the point of
welding. Preheat and interpass temperature must be sufficient to

prevent cracking. Temperature above the minimum may be
required for highly restrained welds. For ASTM A709 Grade 70W

and ASTM A852 Grade 70, the maximum preheat and interpass tem­perature shall not exceed 400ºF for thicknesses thru 1-1/2”, and
450ºF for greater thicknesses.

(2) When the base metal temperature is below 32ºF, preheat to at least

70ºF and maintain this minimum temperature during welding.

WARNING

ARC WELDING can be hazardous.

PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS
INJURY OR DEATH. KEEP CHILDREN AWAY. PACEMAKER
WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE
OPERATING.

Read and understand the following safety highlights. For additional safety infor­mation it is strongly recommended that you purchase a copy of “Safety in
Welding & Cutting - ANSI Standard Z49.1” from the American Welding Society,
P.O. Box 351040, Miami, Florida 33135 or CSA Standard W117.2-1974. AFree
copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric
Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199.

BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE,
AND REPAIR PROCEDURES ARE PERFORMED ONLY BY
QUALIFIED INDIVIDUALS.

-39-

ELECTRIC SHOCK can kill.

1.a. The electrode and work (or ground) circuits are electrically
“hot” when the welder is on. Do not touch these “hot” parts with
your bare skin or wet clothing. Wear dry, hole-free gloves to
insulate hands.

1.b. Insulate yourself from work and ground using dry insula-

full area of physical contact with work and ground.

In addition to the normal safety precautions, if welding must be per­formed under electrically hazardous conditions (in damp locations or
while wearing wet clothing; on metal structures such as floors, gratings
or scaffolds; when in cramped positions such as sitting, kneeling or
lying, if there is a high risk of unavoidable or accidental contact with
the workpiece or ground) use the following equipment:

1.c. In semiautomatic or automatic wire welding, the electrode, electrode reel,
welding head, nozzle or semiautomatic welding gun are also electrically
“hot”.

1.d. Always be sure the work cable makes a good electrical connection with the
metal being welded. The connection should be as close as possible to the
area being welded.

1.e. Ground the work or metal to be welded to a good electrical (earth) ground.

1.f. Maintain the electrode holder, work clamp, welding cable and welding machine
in good, safe operating condition. Replace damaged insulation.

1.g. Never dip the electrode in water for cooling.

1.h. Never simultaneously touch electrically “hot” parts of electrode holders con­nected to two welders because voltage between the two can be the total of
the open circuit voltage of both welders.

1.i. When working above floor level, use a safety belt to protect yourself from a fall
should you get a shock.

1.j. Also see Items 4.c. and 6.

tion. Make certain the insulation is large enough to cover your

• Semiautomatic DC Constant Voltage (Wire) Welder.

• DC Manual (Stick) Welder.

• AC Welder with Reduced Voltage Control.

ARC RAYS can burn.

2.a. Use a shield with the proper filter and cover plates to
protect your eyes from sparks and the rays of the arc
when welding or observing open arc welding. Headshield
and filter lens should conform to ANSI Z87. I standards.

2.b. Use suitable clothing made from durable flame-resistant material to
protect your skin and that of your helpers from the arc rays.

2.c. Protect other nearby personnel with suitable non-flammable screening
and/or warn them not to watch the arc nor expose themselves to the
arc rays or to hot spatter or metal.

-40-

FUMES AND GASES can be

dangerous.

3.a. Welding may produce fumes and gases hazardous to
health. Avoid breathing these fumes and gases.When
welding, keep your head out of the fume. Use enough
ventilation and/or exhaust at the arc to keep fumes and
gases away from the breathing zone. When welding with

stainless or hard facing (see instructions on container or MSDS) or
on lead or cadmium plated steel and other metals or coatings
which produce highly toxic fumes, keep exposure as low as possi­ble and below Threshold Limit Values (TLV) using local exhaust or
mechanical ventilation. In confined spaces or in some circum­stances, outdoors, a respirator may be required. Additional precau­tions are also required when welding on galvanized steel.

3.b. Do not weld in locations near chlorinated hydrocarbon vapors coming
from degreasing, cleaning or spraying operations. The heat and rays of
the arc can react with solvent vapors to form phosgene, a highly toxic
gas, and other irritating products.

3.c. Shielding gases used for arc welding can displace air and cause injury or
death. Always use enough ventilation, especially in confined areas, to
insure breathing air is safe.

3.d. Read and understand the manufacturer’s instructions for this equipment
and the consumables to be used, including the material safety data sheet
(MSDS) and follow your employer’s safety practices. MSDS forms are
available from your welding distributor or from the manufacturer.

3.e. Also see item 7b.

electrodes which require special ventilation such as

WELDING SPARKS

can cause

fire or explosion.

4.a..Remove fire hazards from the welding area. If this is
not possible, cover them to prevent the welding sparks
from starting a fire. Remember that welding sparks and hot
materials from welding can easily go through small cracks
and openings to adjacent areas. Avoid welding near
hydraulic lines. Have a fire extinguisher readily available.

4.b. Where compressed gases are to be used at the job site, special precautions
should be used to prevent hazardous situations. Refer to “Safety in Welding
and Cutting” (ANSI Standard Z49.1) and the operating information for the
equipment being used.

4.c. When not welding, make certain no part of the electrode circuit is touching
the work or ground. Accidental contact can cause overheating and create a
fire hazard.

4.d. Do not heat, cut or weld tanks, drums or containers until the proper steps
have been taken to insure that such procedures will not cause flammable or
toxic vapors from substances inside. They can cause an explosion even
though they have been “cleaned.” For information purchase “Recommended
Safe Practices for the Preparation for Welding and Cutting of Containers and
Piping That Have Held Hazardous Substances”, AWS F4.1 from the
American Welding Society (see address above).

4.e. Vent hollow castings or containers before heating, cutting or welding. They
may explode.

4.f. Sparks and spatter are thrown from the welding arc. Wear oil free protective
garments such as leather gloves, heavy shirt, cuffless trousers, high shoes
and a cap over your hair. Wear ear plugs when welding out of position or in
confined places. Always wear safety glasses with side shields when in a
welding area.

4.g. Connect the work cable to the work as close to the welding area as practical.
Work cables connected to the building framework or other locations away
from the welding area increase the possibility of the welding current passing
through lifting chains, crane cables or other alternate circuits. This can cre­ate fire hazards or overheat lifting chains or cables until they fail.

4.h. Also see item 7c.

-41-

CYLINDER may explode if damaged.

5.a. Use only compressed gas cylinders containing the correct
shielding gas for the process used and properly operating reg­ulators designed for the gas and pressure used. All hoses, fit­tings, etc. should be suitable for the application and main­tained in good condition.

5.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.

5.c. Cylinders should be located:

• Away from areas where they may be struck or subjected to
physical damage.

• Asafe distance from arc welding or cutting operations and
any other source of heat, sparks, or flame.

5.d. Never allow the electrode, electrode holder or any other electrically “hot”
parts to touch a cylinder.

5.e. Keep your head and face away from the cylinder valve outlet when opening
the cylinder valve.

5.f. Valve protection caps should always be in place and hand tight except when
the cylinder is in use or connected for use.

5.g. Read and follow the instructions on compressed gas cylinders, associated
equipment, and CGA publication P-l, “Precautions for Safe Handling of
Compressed Gases in Cylinders,”available from the Compressed Gas
Association 1235 Jefferson Davis Highway, Arlington, VA22202.

FOR ELECTRICALLY powered

equipment.

6.a. Turn off input power using the disconnect switch at the
fuse box before working on the equipment.

6.b. Install equipment in accordance with the U.S. National
Electrical Code, all local codes and the

manufacturer’s recommendations.

6.c. Ground the equipment in accordance with the U.S. National Electrical Code
and the manufacturer’s recommendations.

-42-

FOR ENGINE

7.a Turn the engine off before troubleshooting and
maintenance work unless the maintenance work
requires it to be running.

7.b. Operate engines in open, well-ventilated areas or vent
the engine exhaust fumes outdoors.

7.c.Do not add the fuel near an open flame welding arc or

when the engine is running. Stop the engine and allow it to
cool before refueling to prevent spilled fuel from vaporizing
on contact with hot engine parts and igniting. Do not spill
fuel when filling tank. If fuel is spilled, wipe it up and do not
start engine until fumes have been eliminated.

7.d. Keep all equipment safety guards, covers and devices

in position and in good repair. Keep hands, hair, clothing
and tools away from V-belts, gears, fans and all other mov­ing parts when starting, operating or repairing equipment.

7.e. In some cases it may be necessary to remove safety guards to per­form required maintenance. Remove guards only when necessary
and replace them when the maintenance requiring their removal is
complete. Always use the greatest care when working near moving
parts.

7.f. Do not put your hands near the engine fan. Do not attempt to override
the governor or idler by pushing on the throttle control rods while the
engine is running.

7.g. To prevent accidentally starting gasoline engines while turning the engine or
welding generator during maintenance work, disconnect the spark plug
wires, distributor cap or magneto wire as appropriate.

7.h. To avoid scalding, do not remove the radiator pressure cap
when the engine is hot.

8.a. Electric current flowing through any conductor caus­es localized Electric and Magnetic Fields (EMF). Welding
current creates EMF fields around welding cables and
welding machines.

8.b. EMF fields may interfere with some pacemakers, and welders having a
pacemaker should consult their physician before welding.

8.c. Exposure to EMF fields in welding may have other health effects which are
now not known.

8d. All welders should use the following procedures in order to minimize expo-

sure to EMF fields from the welding circuit:

8.d.1. Route the electrode and work cables together - Secure
them with tape when possible.

8.d.2. Never coil the electrode lead around your body.

8.d.3. Do not place your body between the electrode and
work cables. If the electrode cable is on your right side,
the work cable should also be on your right side.

8.d.4. Connect the work cable to the workpiece as close as
possible to the area being welded.

8.d.5. Do not work next to welding power source.
