SAFETY

PROFILE VIEWS

POSSIBLE CAUSES AND SOLUTIONS

1.Workpiece overheating:

Reduce wire feed speed.

Decrease weld current.

2.Welding speed too slow: Increase welding speed and ensure that welding speed is kept steady.

3.Excessive material at weld:

Reduce wire feed speed.

Bend at Joint

POSSIBLE CAUSES AND SOLUTIONS

1.Improper clamping: Clamp workpieces securely.

Make tack welds to hold workpieces.

2.Excessive heat:

Weld a small portion and allow to cool before proceeding.

Increase weld speed.

Reduce wire feed speed.

PARTIALLY CHIPPED AWAY TO SHOW WELD

Slag is a necessary part of a flux-core wire weld. It shields the weld from impurities. Clean off the slag with the Chipping Hammer and Wire Brush after welding.

POSSIBLE CAUSES AND SOLUTIONS

1.Incorrect welding technique: Maintain 1/2″ or less stickout.

Keep arc on leading edge of weld puddle. Hold torch at proper angles.

2.Insufficient weld heat:

Reduce welding speed.

Increase weld current.

3.Workpieces too thick/close: Bevel thick workpieces, allow slight gap, and weld in several passes.

4.Insufficient weld material: Increase wire feed speed.

Weld Not Adhering Properly

Gaps present between weld and previous bead or between weld and workpiece. See areas below.

POSSIBLE CAUSES AND SOLUTIONS

1.Incorrect welding technique:

Place stringer bead at correct place in joint. Adjust workpiece position or weld angle to permit proper welding to bottom of piece.

Pause briefly at sides during weave bead. Keep arc on leading edge of weld puddle. Hold torch at proper angles.

2.Insufficient weld heat: Increase current. Increase wire feed speed.

3.Dirty workpiece:

Clean workpiece down to bare metal.
