Welding inspection information.

Weld cracks are serious defects that have little margin of safety. The two types of cracking most likely to occur are hot cracking (just after the weld has solidified) and cold cracking (which occurs near room temperature after the weld has cooled).

Most weld cracks are caused by hot cracking, with the weld being pulled apart during cool-down. If the configuration of the part does not allow the weld area to contract as it cools, then hot cracking becomes likely. If the width-to-depth ratio in the weld cross section is too high, edge cooling can pull the bead apart causing centerline cracking.

Hot cracking is common when high phosphorus, sulfur or lead content is present in the base metal. Chromium steels are particularly sensitive to microcracking, but this can be avoided with appropriate preheating procedures.

Methods to control or eliminate hot cracking are usually detailed in work instructions or weld procedures. Variables such as the type of alloy or type of weld can affect the weld sequence and the part's susceptibility to cracking.
