Cracking down on weld cracks

2012-7-16 · 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.
