13-19. Troubleshooting − Burn-Through

Burn-Through − weld metal melting completely through base metal resulting in holes where no metal remains.

Possible Causes

Corrective Actions

 

 

Excessive heat input.

Select lower amperage. Use smaller electrode.

 

 

 

Increase and/or maintain steady travel speed.

 

 

13-20. Troubleshooting − Waviness Of Bead

Waviness Of Bead − weld metal that is not parallel and does not cover joint formed by base metal.

Possible Causes

Corrective Actions

 

 

Unsteady hand.

Use two hands. Practice technique.

 

 

13-21. Troubleshooting − Distortion

 

 

 

Distortion − contraction of weld met-

 

 

 

al during welding that forces base

 

 

 

metal to move.

 

 

Base metal moves

 

 

 

 

in the direction of

 

 

 

 

the weld bead.

 

 

 

Possible Causes

 

Corrective Actions

 

 

 

Excessive heat input.

 

Use restraint (clamp) to hold base metal in position.

 

 

 

 

 

 

 

Make tack welds along joint before starting welding operation.

 

 

 

 

 

 

 

Select lower amperage for electrode.

 

 

 

 

 

 

 

Increase travel speed.

 

 

 

 

 

 

 

Weld in small segments and allow cooling between welds.
