BMS-6 ISO

Stud tip touches
workpiece. Electric arc is
initiated.

Ignited arc generates a
thin fusion zone on stud
and workpiece.

Stud is plunged in molten
pool. Material solidifies
and stud is welded.

2 Description of stud welder

2.1 Description of technology

BMS-6 ISO SOYER stud welding systems function according to the principle of
capacitor discharge (TS) in compliance with DIN EN ISO 14555 and as defined in
DVS information sheet 0903 (German Welding Society).
This system takes advantage of the sudden discharge of a capacitor battery to
generate electric arc energy.

The electric arc is initiated via the calibrated and close-fit ignition tip of the welding
studs and welding elements. The stud weld base and the opposite surface of the
workpiece thus start to melt. The stud is then automatically dipped into the thin fusion
zone or into the liquid weld pool. After immediate solidification of the material, an
homogenous high-strength joint is produced in an extremely short welding time of only
1 – 3 milliseconds (0.001 – 0.003 sec.).

2.2 Stud welder set-up

The standard gun to be connected to the BMS-6 ISO stud welder is the PS-1 stud
welding gun with control cable and support tube.
Optionally it is possible to connect the PS-1KI stud welding gun for cupped head pins
or the PS-3K, PS-0K, PS-1K contact guns for studs and insulating nails with ignition
tip to the stud welder. These operating instructions only refer to the BMS-6 ISO stud
welder.

For information regarding the stud welding guns required and their adjustment, please
refer to the relevant operating instructions of the stud welding guns.

6 Quality control

6.1 General

The DVS Guideline 0905, part 2, of April 1979 is applicable with regard to quality
assurance of stud weld joints. The tests described in this section are written in
simplified terms, following above regulation. They refer to work tests that are carried
out and supervised by the user prior to and during welding.

Heinz Soyer Bolzenschweißtechnik GmbH is member of the German Welding Society
(DVS = Deutscher Verband für Schweißtechnik e. V.), Munich.

6.2 Demands on the company

The company must employ a technical supervisor responsible for welding matters, as
well as qualified operating personnel for stud welding (see DVS Guideline 0905, part
2, section 4).

6.3 Proof of qualification

In the case of components which documentation must be provided for, or stud welding
works which as per DIN 14100, DIN 4113 are subject to acceptance, the processing
company must submit a certificate of competence or a proof of qualification for
working with stud welding equipment (see DVS Guideline 0905, part 2, section 4.1
and 4.2). The proof of qualification applies in particular to the fastening of structures
that are relevant in terms of safety regulations. When being used in the building
industry, only approved base and stud materials may be used (for example, see DIN
4001, section 2.1, certificate of approval for stainless steel ifBT, DIN 4113, part 2).

6.4 Type and scope of test

Provided that the SOYER stud welding equipment is properly used and the materials
are appropriately selected, the strength of the welding joint (welding zone) will always
be stronger than that of the stud or base material.
The following tests are carried out in general practice:

•Standard work test (see DVS Guideline 0905, part 2, section 5.1.2).

•Simplified work test (see DVS Guideline 0905, part 2, section 5.1.2).

6.4.1 Standard work test

Generally, standard work tests have to be carried out and supervised by the user
before welding at a structure and after a certain number of welds has been made. The
number of welds after which a standard work test is required is agreed upon with the
customer.

The standard work test is restricted to the stud diameter, base material and type of
equipment used. It comprises the following tests:

• Visual inspection (all samples)

• Tensile test (at least 3 samples)

• Bend test (at least 3 samples)

28

BMS-6 ISO

When in doubt, the test scope should be extended in compliance with DVS Guideline
0905, part 2, section 5.1.1.

6.4.2 Simplified work test

Simplified work tests serve to check the correct setting and function of the equipment.
They are carried out at the beginning of every working shift and after several hours of
interruption.

Simplified work tests include:

• Visual inspection (all samples)

• Bend test (all samples)

6.5 Test execution

6.5.1 Production of samples

The studs for the work test are welded on a sheet metal the minimum size of which is
700 mm x 200 mm. Use the same welding positions and edge distances as on the
component to be welded later. If it is possible and sensible from an economical point
of view, use parts that are identical to those used in later production.

6.5.2 Visual inspection

The visual inspection serves as a rough check for major defects. The uniformity of the
weld is assessed. When in doubt, tensile and bend tests should be carried out.

6.5.3 Tensile test

The tensile test serves to test the metallic bond of the stud with the base metal. At
least 3 studs are welded and then axially loaded by means of an appropriate tension
device until they break. If the customer demands that a certain percentage of the
welded studs should be tested with a specific test load in production, a tension device
with load indicator should be used.
If the stud breaks outside the welding zone, the test is regarded as successful. If it
breaks within the welding zone, however, the fractured surface must be examined.
The unwelded surface may not exceed a maximum 20% of the welding surface. When
in doubt, the breaking load in accordance with DIN 267, part 3, should be determined.
If the quantity of defective studs in one random sample exceeds the acceptance
number specified in DIN 267, part 5, as per AQL 4, it is necessary to find out the
reason for the faults. The setting values must be modified and the test repeated.

6.5.4 Bend test

The bend test is a simple work test which serves to roughly check the setting values
selected. The welding zone is subjected to undefined tension, pressure and bending.
A minimum of three studs is welded and bent to an angle of 30° by means of a tube
that is slipped over the stud. The test is considered as successful, if no superficial
fissure or fracture is detected in the welding zone. The acceptance number in
accordance with DIN 267, part 5, as per AQL 4 must be complied with. If the quantity
of defective parts in one inspection lot exceeds the acceptance number AQL 4 (see
DIN 267), the cause of trouble must be determined and the test repeated again.

1.4 Adjustment of spring pressure

The pressure with which the stud is pressed against the workpiece during the
welding process is called spring pressure.

The illustration below shows how to adjust the spring pressure of PS-1 stud
welding gun which is equipped with a spring pressure indicator. The PS-3K
stud welding gun is equipped with a similar spring pressure indicator. The PS­0K and PS-1K welding guns do not have a spring pressure indicator.

1 Adjusting screw 2 Spring pressure indicator

The spring pressure for all stud welding guns described here is adjusted by
means of the adjusting screw (1). The adjusted spring pressure is indicated on
the spring pressure scale (2). Adjust the spring pressure as follows:

• Turn adjusting screw (1) to the left until stop
Indicator position 1 = low pressure

• Turn adjusting screw (1) 3.5 turns to the right
Indicator position 2 = medium pressure

• Turn adjusting screw (1) to the right until stop
Indicator position 3 = strong pressure

The adjustment of spring pressure depends on the material of both the welding
stud and the workpiece.

Before starting work, carry out some experimental welds and test them to find
out the optimum adjustment.

Several samples have to be taken during production to ensure constantly good
welding results (see DVS Guideline 0905, part 2, "Quality assurance of stud
welding joints").

1 Adjustment of PS-1KI stud welding gun

1.1 Adjustment of cupped head pin retainer

Instead of a stud holder the PS-1KI stud welding gun has a cupped head pin
retainer (1). The adjustment of the stud welding gun is confined to the
adjustment of the spring pressure which holds cupped head pins (4) in the
cupped head pin retainer. The spring pressure, which has to be adjusted by
means of three grub screws (3), determines how firmly the cupped head pin is
held in the cupped head pin retainer. The cupped head pin is inserted against
the spring pressure. Thereby the cupped head pin has to be pressed axially into
the cupped head pin retainer against the spring pressure which is exerted on
three balls located at an angle of 12°.

Adjust the spring pressure as follows:

• Loosen hexagon socket screw (2) and remove cupped
head pin retainer (1) from the support tube.

• Turn grub screws (3) clockwise
= increase of spring pressure (holding force)

• Turn grub screws (3) anticlockwise
= decrease of spring pressure (holding force)

1.2 Installation of cupped head pin retainer into stud welding gun

The cupped head pin retainer has to be installed into the stud welding gun as
follows:

• Turn sleeve nut (6) anticlockwise by means of socket wrench SW17.

• Insert retaining pin (5) into spring piston until stop.

• Turn sleeve nut (6) clockwise by means of socket wrench SW17 and secure
retaining pin (5) (hand-tighten the sleeve nut).

• Attach support tube (3) to gun and secure by means of three hexagon socket
screws (4).

• Insert cupped head pin retainer (1) into support tube (3) and secure by means
of hexagon socket screw (2).

1 Cupped head pin retainer 4 Hexagon socket screw
2 Hexagon socket screw 5 Retaining pin
3 Support tube 6 Sleeve nut

After installation of the cupped head pin retainer, check proper function as
follows:

• Press cupped head pin retainer (1) about 5 mm into the support tube (3)
against the spring pressure.

• Release pressure. The cupped head pin retainer is moved into its original
position by the spring pressure. If the cupped head pin retainer gets caught
in the pressed position, it has to be removed and cleaned. Clean the interior
of the support tube as well. If these measures do not have any effect, replace
the components.

1.3 Adjustment of spring pressure

The pressure with which the stud is pressed against the workpiece during the
welding process is called spring pressure.

The following illustration shows how to adjust the spring pressure.

1 Adjusting screw 2 Grub screw

Adjust spring pressure by means of adjusting screw (1) as follows:

• Turn adjusting screw (1) anticlockwise until stop
= low pressure

• Turn adjusting screw (1) 3.5 turns clockwise
= medium pressure

• Turn adjusting screw (1) clockwise until stop
= high pressure

• Hand-tighten grub screw (2) by turning it clockwise by means of socket
wrench SW2.

FFAfter having adjusted the spring pressure, fix it by means of the headless

pin (2).

The setting of the spring pressure depends on the material of both welding stud
and workpiece.

Before starting the work, carry out some experimental welds and test them to
find out the optimum setting.

Samples have to be taken during production to ensure constantly good weld­ing results (see DVS Guideline 0905, part 2, "Quality assurance of stud
welding joints").
