SAFETY SERVICEBASIC WELDING WELDING TIPSSETUP
Weld Not Adhering Properly
Gaps present between weld and previous bead or
between weld and workpiece. See areas below.
POSSIBLE CAUSES AND SOLUTIONS
Incorrect welding technique:1.
Place stringer bead at correct place in joint.
Adjust workpiece position or weld angle to
permit proper welding to bottom of piece.
Pausebrieyatsidesduringweavebead.
Keep arc on leading edge of weld puddle.
Hold gun at proper angles.
Insufcient weld heat: 2.
Increase current and/or wire feed speed.
Dirty workpiece:3.
Clean workpiece down to bare metal.
Insufcient weld material: 4.
Increase wire feed speed.
Bend at Joint
POSSIBLE CAUSES AND SOLUTIONS
Improper clamping:1.
Clamp workpieces securely.
Make tack welds to hold workpieces.
Excessive heat:
Weld a small portion and allow to cool
before proceeding.
Increase weld speed.
Reduce wire feed speed.
EXCESS PENETRATION OR
BURN-THROUGH
Weld droops on top and
underneath, or falls through
entirely, making a hole.
PROPER PENETRATION
Weld is visible underneath and
bulges slightly on top.
INADEQUATE PENETRATION
Weld does not contact the joint
fully, just on the surface.
POSSIBLE CAUSES AND SOLUTIONS
Workpiece overheating: 1.
Reduce wire feed speed.
Use MIN setting.
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.
POSSIBLE CAUSES AND SOLUTIONS
Incorrect welding technique:1.
