Incomplete Fusion

Using welding parameters that are too high in current and/or voltage

Improper joint design causing inconsistencies in preparation and fit-up

Failure to remove rust and mill scale from the joint prior to welding

Failure to fuse between weld metal and fusion faces or adjoining weld beads (correct)

Failure to remove rust and mill scale from the joint prior to welding

Using welding parameters that are too high in current and/or voltage

Improper joint design causing inconsistencies in preparation and fit-up

Improper electrode selection inhibiting electrode manipulation (correct)

Narrow V-groove weld in a thick plate inhibiting electrode manipulation (correct)

Uneven root faces and bevel angles in the joint preparation
