47 Transverse Cracks

Transverse cracks are cracks in a weld perpendicular to the axis of the weld and sometimes extending beyond the weld in the base metal. Transverse cracks in steel weldments are usually related to hydrogen embrittlement. Transverse cracks appear as tight, relatively straight cracks perpendicular to the weld axis.

Transverse Crack Prevention

Transverse crack prevention depends on the specific welding situation. For example, transverse cracks may be caused by using incorrect filler metal composition, rapid cooling, or a weld that is too small for the part being joined.

Depending on the situation, transverse cracks may be eliminated by using the proper filler metal composition, higher welding current or preheat, or a larger filler metal and final weld dimension, respectively.
