Web16 jul. 2012 · The crack generally is directed down into the base metal, right at the weld toe. If you don’t create a smooth transition of weld metal to base metal, you can disrupt the flow of forces through the weld. Such a high volume of weld metal creates significant shrinkage forces. When these forces exceed the strength of the weld, cracking ensues. Hydrogen embrittlement is a complex process involving a number of distinct contributing micro-mechanisms, not all of which need to be present. The mechanisms include the formation of brittle hydrides, the creation of voids that can lead to high-pressure bubbles, enhanced decohesion at internal surfaces and localised plasticity at crack tips that assist in the propagation of cracks. T…
