Cracking down on weld cracks The Fabricator

Jul 16, 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.Understanding end mill run-out CutterPlus+,Feb 12, 2016· When an end mill is in rotation it is important that each tooth hits at the exact same spot along the work piece. If one tooth is hitting the work piece more than the others then that tooth is doing the bulk of the work. This will cause the end mill to wear and breakdown more quickly.
