Torch Manipulations
No discussion of welding techniques
would be complete without some reference to the methods of torch
manipulation. The recommendations which
follow are only to serve as a guide to be used during welder
training. As the individual welders
become more proficient with the Mig process, they will adapt their torch
manipulations to best suit the job at
hand. FLAT POSITION
Recommended weaving patterns, torch
positions and bead sequence are shown in Figure
7-15. For the single-pass,
butted joint, a slight back-stepping motion is used. Gapped root passes are made
with a small, back-and-forth
weave pattern. For fill and cover passes, the same weave, with an adjustment for
the desired width,
is used, with care taken to pause at the sidewalls to obtain adquate fill in these
areas.
