Welding Quality
Most
often, the major metric used for judging the quality of a weld is its
strength and the strength of the material around it. Many distinct
factors influence this, including the welding method, the amount and
concentration of heat input, the base material, the filler material,
the flux material, the design of the joint, and the interactions
between all
these factors. To test the quality of a weld, either
destructive or nondestructive testing methods are commonly used to
verify that welds are defect-free, have acceptable levels of residual
stresses and distortion, and have acceptable heat-affected zone (HAZ)
properties. Welding codes and specifications exist to guide welders in
proper welding technique and in how to judge the quality of welds.
