SAFETYSERVICE BASIC WELDINGWELDING TIPS SETUP
Coat of Slag Over Weld
Slag is a necessary part of a ux-
core wire weld. It shields the weld from
impurities. Clean off the slag with the
Chipping Hammer and Wire Brush after
welding.
Burn-Through
Base material melts away,
leaving a hole in the weld.
POSSIBLE CAUSES AND SOLUTIONS
Workpiece overheating: 1.
Reduce current and/or wire feed speed.
Welding speed too slow:2.
Increase welding speed and ensure that
welding speed is kept steady.
Excessive material at weld: 3.
Reduce wire feed speed.
Porosity
Small cavities or holes in the bead.
POSSIBLE CAUSES AND SOLUTIONS
Dirty workpiece or welding wire:1.
Clean workpiece down to bare metal.
Make certain that wire is clean and free
from oil, coatings, and other residues.
Inconsistent welding speed: 2.
Maintain steady weld speed.
Stickout too long:3.
Reduce stickout.
Excessive Spatter
Fine spatter is normal.
Spatter that is grainy and large is a problem.
POSSIBLE CAUSES AND SOLUTIONS
Dirty workpiece or welding wire:1.
Clean workpiece down to bare metal.
Make certain that wire is clean and free
from oil, coatings, and other residues.
Wire feeding too fast:
2.
Reduce wire feed speed.
Stickout too long:3.
Reduce stickout.
Crooked/Wavy Bead
POSSIBLE CAUSES AND SOLUTIONS
Inaccurate welding:1.
Use two hands or rest hand on steady
surface.
Inconsistent welding speed: 2.
Maintain steady weld speed.
Stickout too long:3.
Reduce stickout.
