12-14. Troubleshooting − Porosity

Porosity − small cavities or holes resulting from gas pockets in weld metal.

Possible Causes

Corrective Actions

 

 

Arc length too long.

Reduce arc length.

 

 

Damp electrode.

Use dry electrode.

 

 

Workpiece dirty.

Remove all grease, oil, moisture, rust, paint, coatings, slag, and dirt from work surface before

 

welding.

 

 

12-15. Troubleshooting − Excessive Spatter

Excessive Spatter − scattering of molten metal particles that cool to solid form near weld bead.

Possible Causes

Corrective Actions

 

 

Amperage too high for electrode.

Decrease amperage or select larger electrode.

Arc length too long or voltage too high.

Reduce arc length or voltage.
