In welding, an "undercut" refers to a defect that occurs when the base metal is melted away at the edges of the weld joint during the welding process, resulting in a groove or notch. This can happen if the weld pool is too hot or if there is improper control of the welding parameters. The undercut can compromise the structural integrity of the joint by creating a weak spot that may lead to failure under stress or load.
