SETUP

Stick Weld - coat of Slag Over Weld 

TOP 

VIEW

PARTIALLY CHIPPED AWAY TO SHOW WELD

Slag is a necessary part of a stick weld.  It shields 
the weld from impurities.  clean off the slag with the 
chipping Hammer and Wire Brush after welding.

Stick Weld - porosity 

- Small cavities or holes in the bead.

dirty workpiece or fill material:

 

Clean workpiece down to bare metal.  

Make certain that fill material and Electrode are 

clean and free from oil, coatings, and other residues.

2. 

Inconsistent welding speed: 

Maintain steady weld speed.

1. 

Inaccurate welding:

 

Use two hands or rest hand on steady surface.

2. 

Inconsistent welding speed: 

Maintain steady weld speed.

Stick Weld - Excessive Spatter 

pOSSIBLE cAUSES ANd SOLUTIONS

TOP 

VIEW

Fine spatter is normal. Spatter that is 
grainy and large is a problem. 

dirty workpiece or fill material:

 

Clean workpiece down to bare metal.  
Make certain that fill material and Electrode are 
clean and free from oil, coatings, and other residues.

Stick Weld - Burn-Through 

-  Base material melts away, leaving a hole in the weld.

1. 

Workpiece overheating: 

Reduce current. 

2. 

Welding speed too slow:

 

Increase welding speed and ensure 

that welding speed is kept steady.

3. 

Excessive material at weld: 

Reduce amount of fill material.
