What Is It?
Tandem MIG is a dual wire GMAW process that is
used in automated welding applications to improve
welding productivity and part throughput. The process
utilizes two welding power sources and two wire
feeders acting in tandem to deliver two wire electrodes
through a single welding torch. The dual wire welding
torch, capable of often doubling the welding output of
a single wire torch, is used in hard automation and
robotic arc welding cells in the same manner as a
single wire welding torch would be. The two welding
arcs that are generated in the Tandem MIG process
are electrically isolated from one another and are

controlled independently. The welding arcs work
together, generally separated by less than 0.50 inches,
in the same weld pool. The independent control of the
two welding arcs is used to control the thermal and
fluid dynamics of the weld pool to further enhance
welding performance. The added deposit rate achieved
by the dual wire delivery and the added weld pool
control is used to overcome single wire limitations to
produce high travel speeds and electrode melt-off
rates (weld metal deposition). Special power source
welding software is used to allow the two welding arcs
to operate in unison.

How Does It Work?
The two welding arcs common to the Tandem MIG
process have distinct functions. The lead arc (the
first arc in the direction of torch travel) is operated in
a spray transfer mode. The mode may be either a
special Tandem MIG pulse mode, an adaptive
constant voltage mode or a Tandem MIG power mode.
The lead arc’s primary function is to establish initial
root penetration and develop a molten weld pool for
the trail wire. While performing these functions the
lead wire typically accounts for 60% or more of the
total weld metal deposited. The trail arc or second arc

is operated in a special Tandem MIG pulse mode.
The trail arc’s function is to add filler metal to the weld
pool and control the bead characteristics such as edge
wetting, physical contour, side-wall penetration and
weld pool follow speed. The trail arc should be kept
directly in line with the lead arc and focused on the
center of the weld pool. The trail wire melting rate
typically represents approximately 40% of the
process deposition rate. The Tandem MIG trail pulse
waveforms are designed to operate at low voltages
to limit arc interaction and minimize arc blow.

High-Speed and High-Deposition Welding
Comparing High-Speed Tandem MIG
To Single Wire GMAW Processes
Better Weld Metal Follow Characteristics:
Problem - Single Wire GMAW
As higher travel speeds are explored with conventional
single solid and metal cored wire GMAW processes
one of the factors that limits obtainable travel speeds
is a phenomenon referred to as “bead humping” or
lack of follow. The lack of follow occurs as a number
of physical metal flow requirements break down. The
coalescent properties of the weld pool are not strong
enough to pull the puddle along while, at the same
time, the higher travel speeds limit the heating of the
plate that would normally allow the weld pool to wet
or flow along the weld bead edges.
Solution - Tandem MIG
The spacing of the two arcs of the Tandem MIG
process is designed to overcome the lack of follow
associated with single wire GMAW processes. The
lead arc provides initial penetration into the base plate
and a preheating of the plate for the trail arc. The trail
arc rides the pool created by the lead electrode, the
pressure from the trail arc flattens the created weld
pool to eliminate the tendency for the pool to rise and
hump. The applied weld pool pressure from the trail
arc is used to not only limit the tendency of the lead
weld pool to hump and lose follow capability, but the
pressure is adjustable, allowing the bead contour to be
modified to meet application requirements.
6/16
12 Gauge Lap Weld
at 120 ipm travel
Reduced Tendency Towards Burn-through and Undercut
Problem - Single Wire GMAW
Increased travel speeds require the use of larger wire
diameters or higher wire feed speeds. Both choices
will cause an increase in current draw. The added
current draw creates added penetration that must
be managed. With a single wire GMAW process the
penetration is most intense at the point where the
axial flow of material from the welding wire is directed
on to the plate. This area is focused to a small area
that is generally the cross-sectional area of the
welding wire diameter. In order to manage the
additional finely focused penetration wire placement
becomes more demanding, joint fit-up becomes
more critical. If joint alignment is not maintained and
the welding arc wanders off the seam, concentrating
the arc on a single metal thickness, burn-through is a
common result. If joint fit-up is not maintained welds
often penetrate well into the open joint creating an
unacceptable undercut. If the penetration is not
successfully managed the common result is costly
increased rework or scrap.
Solution - Tandem MIG
The Tandem MIG process is able to achieve the
high wire feed requirements of high speed welding
without creating excessive penetration. The required
wire feed total for high speed welding is shared by
the two electrodes forming the Tandem MIG process.
The shared wired feed speed not only reduces the
current draw on each individual arc but disperses
the total welding energy over two separate focal
points. The separation of the two focal penetration
points allows more metal to be deposited without
excessive penetration. The lead arc is focused on
the plate while the trail arc is focused on the molten
pool created by the lead arc. The trail wire energy is
applied to the pool and not directly onto the plate. This
limits the overall penetration and allows the process
to be tolerant of joint misalignment and joint gaps.
The future of welding is here.

Higher Deposition rates
Problem - Single Wire GMAW
A conventional single wire GMAW process has an
optimum operating range based primarily on wire
diameter, shielding gas and wire feed speed.
Attempting to maximize deposition rates for a given
wire diameter requires increasing the wire feed rate
to the top or beyond its defined operating range. As
the process is pushed to its limit, arc instability is often
a result. Arc instability creates increased spatter levels
and weld porosity. The elevated welding currents
create weld pool turbulence that can cause root
porosity, or porosity just below the surface of the
weld bead.
Solution - Tandem MIG
The two-wire electrode configuration of the Tandem
MIG process allows a higher total wire feed rate,
creating a higher deposition rate. Each electrode in
the Tandem configuration can be operated within an
optimum operating range as defined by a single wire
process. Both the lead and the trail electrode may be
operated in a stable operating range, while the
combined wire feed speed of the two electrodes often
exceed a useable single wire process by 35-80%.
The future of welding is here.

High-Speed and High-Deposition Welding
Comparing High-Deposition Tandem MIG
To Single Wire GMAW Process
Reduced Heat Input and Improved Bead Profiles
Problem - Single Wire GMAW
A single wire GMAW process has a useable weld
metal deposition rate based on wire feed speed and
wire diameter. In an attempt to increase weld metal
deposit rates, rather than push a given wire diameter
to unstable wire feed speeds, it is often common
practice to increase the wire diameter and operate
within stable wire feed ranges. The increase in wire
diameter increases the required current draw
associated with a given weld metal deposit rate.
Increased current draw produces higher heat inputs
leading to part distortion and a large fluid weld pool
that is difficult to control.
Solution - Tandem MIG
With the Tandem MIG process the two smaller
diameter electrodes produce a lower heat input and
improved weld pool control when compared to a larger
single electrode process attempting to perform similar
welds. When compared to larger diameter electrode
processes,Tandem MIG typically reduces heat input
by as much as 30-50%. The trail electrode in the
Tandem MIG process is operated in a special Tandem
MIG pulse mode designed to cool the weld pool
created by the lead electrode. The combination of
lower total heat input and the cooling affect of the trail
electrode, allows the trail electrode to be used to help
control weld bead contour. This provides the ability
to better stack horizontal weld beads and produce
flatter horizontal fillets while working at higher
deposition rates.

Using Tandem MIG
Understanding Operating Variables
The general rules governing operating variables for single wire GMAW arc welding also apply to Tandem MIG
welding. However there are additional considerations that must be kept in mind when welding with multiple arcs.
Since the two arcs will interact, the type of power fed to each arc, the wire feed speed ratio between lead and trail,
the arc lengths, the wire positioning, and torch angles must be set correctly. The enclosed procedures are starting
points and may need to be altered based on specific application conditions. Adherence to the following guidelines
will assist in achieving the maximum potential of the process.
Lead Arc
The lead arc creates the majority of the penetration and should represent the majority of the total deposition
rate of the process. When using like diameter electrodes for the lead and the trail, the lead should represent
approximately 60% of the total wire feed. In the case where a larger wire diameter is used as a lead (for added
penetration) the lead should represent approximately 60% or more of the total deposition. The lead arc can be
operated in a Tandem pulse, CV or Power mode. Pulse is recommended for the high deposition procedures.
Power mode or CV may be used for greater lead arc stability in high travel speed applications.
Trail Arc
The trail arc is used to cool the weld pool and control the bead contour and is always operated in the Tandem
pulse mode. The trail should be kept directly in line with the lead arc and focused on the center of the weld pool.
The trail wire should represent approximately 40 % of the process deposition rate. The Tandem MIG trail pulse
waveforms are designed to operate at low voltages to limit arc interaction and minimize arc blow.
Torch Positioning
Torch positioning may be altered for specific applications. A 5-degree push angle is recommended for high
deposition welding. A (0-5)-degree angle is recommended for high speed welding.

Understanding Operating Variables
Shielding Gas
The lead and trail shielding gas should be of the same mixture and supplied through separate flow regulators. Gas
flow per electrode should be a minimum of 40-cfh each. High deposition procedures may require flow rates as
high as 70 cfh per electrode. High deposition multi-pass applications may require that a trailing gas is applied to
eliminate nitrogen pick-up. The Tandem MIG process requires a binary gas mixture capable of supporting a spray
transfer. Argon/Carbon dioxide or Argon/ Oxygen are the preferred mixtures.

2. 82-95% argon with a Ar/C02 binary mixture is a useable range, The higher CO2% will promote added
penetration but may produce added spatter. The lower CO
3. 95/5%, Ar/O2is recommended for high speed welding of thin gage material under 3mm. The

towards the work lead connection may cause a convex weld bead and undercut.

Tandem MIG
High-Speed and High-Deposition Welding
Lincoln Consumables used with Tandem MIG
SuperArc®/SuperGlide
Lincoln’s SuperArc, our premium copper-coated MIG wire, and
SuperGlide, our premium bare wire, are the choice of welders
and welding decision-makers everywhere because of their
exceptional consistency, feedability, and arc action.
A better arc means less spatter, less clean-up, and improved
productivity – and premium SuperArc and SuperGlide deliver
the best arc in MIG welding.
Our MicroGuard™ Ultra surface treatment,
with proprietary arc enhancement agents,
facilitates excellent weld puddle control, very
good wetting action, straight bead edges, and
a wider operating range.
The exceptional feeding characteristics of
SuperGlide, made possible by MicroGuard Ultra
surface treatment, translate to reduced
down-time and high operator appeal.
Accu-Pak
100% Recyclable Patented Package — when the
wire is consumed, just remove the components,
