Stick Weld Penetration (Workpiece Heat Control)
eXceSS penetRatiOn OR
BURn-tHROUgH
Weld droops on top and
underneath or falls through
entirely, making a hole.
pOSSiBle caUSeS and SOlUtiOnS FOR
eXceSS penetRatiOn OR BURn-tHROUgH
1. Workpiece overheating:
Reduce current.
2. Welding speed too slow:
Increase welding speed and ensure
that welding speed is kept steady.
Stick Weld - Weld not adhering properly
gaps present between weld and previous bead or between weld and workpiece. See areas below.

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.
Keep arc on leading edge of weld puddle.
Hold Electrode and fill material at proper angles.

inadeQUate penetRatiOn
Weld does not contact the joint
fully, just on the surface.
pOSSiBle caUSeS and SOlUtiOnS FOR
inadeQUate penetRatiOn
1. incorrect welding technique:
Keep arc on leading edge of weld bead puddle.
Hold torch at proper angles.
2. insufficient weld heat:
Slow down so fill material has time to melt
into the weld location. Increase current.
3. Workpieces too thick/close:
Bevel thick workpieces, allow slight
gap, and weld in several passes.
4. insufficient weld material:
Increase amount of fill material.
2. insufficient weld heat:
Increase current.
3. dirty workpiece:
Clean workpiece down to bare metal.
4. insufficient weld material:
Increase amount of fill material.
5. distance between workpieces to large:
Decrease distance and increase bevel.
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.
