Regular, bright and complete collar.
Poor weld quality e.g. caused by excessive welding energy or
insufficient plunge or lift.
Reduced diameter weld. Partial weld.
Poor weld quality e.g. caused by insufficient welding energy or humid
ceramic ferrules.
Reduced and irregular collar.
Poor weld quality, e.g. caused by arc blow, tilted or unsteady welding
position of welding gun.

undercuts are visible.
