Tandem MIG
Using Tandem MIG
For High-Deposition Applications
Flat and Horizontal Fillet Welds
6 mm and Larger
Railroad, Structural, Industrial
Equipment, Ship Building, Off Road
Wheel Manufacturing
Flat and horizontal fillets common to structural
building components, offshore platforms, railcar
haulers, machine bases, large vehicle wheels,
undercarriages/truck suspensions and other fabricated
components of metal thickness of 6 mm and greater
are performed at deposition rates ranging from
21 - 35 lbs./hr.
Single pass 5/16” flat fillets are commonly welded
at 24 - 30 ipm with (2) .045” diameter electrodes.
Single pass 5/16” flat fillets are commonly welded
at 27 - 40 ipm with (2) .052” diameter electrodes.
Bevel and “V” Groove Joints
Heavy Plate Fabrication, Structural
Members and Industrial Equipment
Single and multi-pass beveled butt welds used
in industries fabricating ship hulls, earth moving
equipment, structural platforms, pressure vessels,
beams and similar heavy plate weldments are
performed at deposition rates ranging from
22 - 35 lbs./hr. Welds are commonly performed using
like electrode diameters, either .045 or .052 inch
diameter. The lead electrode provides root penetration,
the trail electrode adds to sidewall penetration.
“J” and “U” Groove Butt Welds
Earth Moving Equipment and
Heavy Plate Fabrication
Single and multi pass “J” and “U” groove joints
common to undercarriages, rollover protection
equipment, sticks, booms, fifth wheels, frames,
hydraulic cylinders, pant legs and similar earth
moving equipment components are welded at
deposition rates ranging from 22 - 35 lbs./hr. Welds
are performed at a 30 - 50% reduction in heat input
when compared to larger diameter single electrode
processes. Lower heat input can substantially reduce
post weld straightening activity caused by distortion.
1/2” Flat Fillet at 20 ipm
8 mm Horizontal Fillet
Multi-pass Butt Weld
2 Pass “J” Groove
