text: definition of "stitch welding"? what is the exact definition of a stitch weld. does it technically only apply to spot welding, or is it any weld made for a certain length every so many inches c/c. thanks. stitch welding means that you would weld for a set length, skip another set length, then weld the set length again. stitch welding usually applies to normal bead welding and not to spot welding (because spot welding by definition is not continuous). the size of the weld and the skip can vary, based on the joint design requirements.
