Common Welding Defects Every Inspector Should Know

Porosity - Small holes due to trapped gas in weld
Cracks - Breaks in weld due to stress or poor technique
Lack of Fusion - Weld metal not properly fused with
base metal
Undercut - Groove formed at the edge of weld
Overlap - Weld metal flows over base metal without
bonding
Spatter - Small metal droplets scattered around weld
Slag Inclusion - Slag trapped inside weld metal Poor Pe*******on - Weld does not pe*****te fully
Underfill - Weld surface below base metal level
Excess Reinforcement - Too much weld metal deposited
Burn Through - Hole created due to excessive heat Arc Strike - Unwanted arc marks outside weld area
Crater Crack - Crack formed at the end of weld
Excessive Convexity - Weld surface too high/rounded
Misalignment - Improper alignment of joint
Oxidation - Surface contamination due to poor shielding
