62 Incorrect Shape

An incorrect shape in a weld includes any weld discontinuity that produces an unacceptable weld profile or dimensional nonconformance and that adversely influences performance of the weld under load. An insufficient cross-sectional area of a weld may result in a weld that is unable to support a load, or may allow a stress-concentrating notch, leading to fracture. Incorrect shape discontinuities are undercut, overlap, excessive weld reinforcement, underfill, and concave root surface.
