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
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.
