Longitudinal cracks run along the length of a weld bead. There are three types: check cracks, root cracks, and full centerline cracks. Check cracks are visible from the surface and extend partially into the weld. They are usually caused by high shrinkage stresses, especially on final passes, or by a hot cracking mechanism.

WebHeat affected zone (HAZ) cracking (Figure 5) is charac-terized by separation that occurs immediately adjacent to the weld bead.
