APPLICATION W A V E F O R M C O N T R O L T E C H N O L O G Y T M Tandem MIGTM High-Speed and High-Deposition Welding Low cost and profitability are key business objectives, whether the product offering is a wheel, a water tank, or a truck frame. It used to be thought that on the road to lower cost, quality had to be sacrificed. That’s no longer true with Tandem MIG welding. Fast travel speeds on thin lap welds increase the number of parts per day. The following factors affect pricing per welded part: • • • • Capital Equipment Overhead Labor cost Part production rates Lincoln Tandem MIG welding systems are designed to produce quality welds at welding speeds well above accepted single wire processes. The unique engineered output control of the Tandem MIG dual wire process is designed to overcome the barriers limiting the travel speed capabilities of conventional single wire GMAW processes. Increased deposition on thicker materials reduces welding time and distortion. a d v a n t a g e s INCREASED TRAVEL SPEEDS • The combined contribution of two separate welding arcs in one weld pool provides the control to overcome the lack of follow tendencies of single arc processes. INCREASED DEPOSITION • Two small diameter Tandem MIG wire electrodes provide higher melt-off rates per current drawn when compared to a single larger diameter wire electrode at similar current draws. IMPROVED THROUGHPUT • Higher travel speeds and higher deposition rates reduce part welding time cycles. T h e f u t u r e o f w e l d © Copyright 2005 The Lincoln Electric Company.

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.

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. Lead and Trail arc functions for high speed welding Lead and Trail arc functions for high deposition welding Trail arc is focused on the crest of the pool created by the lead. The trail arc is focused on the middle of the weld pool to create additional fill.

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. 12 Gauge Lap Weld at 120 ipm travel 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. 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 Reduced Tendency Towards Burn-through and Undercut Problem - Single Wire GMAW Solution - Tandem MIG 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. 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.

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 T h e f u t u r e o f 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%. w e l d i n g i s h e r e . ® W A V E F O R M C O N T R O L T E C H N O L O G Y T M APPLICATION Tandem MIG 8/16 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 Solution - Tandem MIG 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. 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.

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. Joint Angle Travel Angle Push PushAngle Angle 90° 65° Horizontal Welds Lap Flat Welds (Beveled Butt, Fillets, Laps 1/2” Wire Dia.

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. 1. 90/10%, Ar/CO2 is preferred for most welding applications. 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 CO2 % will produce less spatter. 3. 95/5%, Ar/O2 is recommended for high speed welding of thin gage material under 3mm. The mixture will provide improved wetting at bead edges and reduced tendency to erode away edges of lap welds. Work Lead Connection Tandem MIG welding should be performed welding in the direction from the work lead connection. Welding towards the work lead connection may cause a convex weld bead and undercut. Joint Selection The Tandem MIG process is ideal for many joint configurations. A joint application rating is as follows: Excellent 1. Lap welds in the flat, horizontal, 3 o'clock position. 2. Fillet welds in the flat and horizontal positions. 3. Joggle welds in the flat position. 4. Beveled butt welds in flat position. 5. "J" Groove welds. 6. Rotated roundabouts, lap and joggle welds. Good 1. Beveled butt welds in horizontal position. 2. Horizontal flare joint. Poor 1. Seamer applications. 2. Joints known to be subject to arc blow. 3. Weld joints that have multiple or severe turns in direction or contour. 4. Thin gage square edge butt welds.
