Productivity and IE in Iron and Steel Pipe and Tube Manufacturing

Hot cracking — cracks that occur immediately upon completion of the weld — are the biggest potential threat when welding austenitic stainless steel tube and pipe. This material is particularly susceptible to this defect due to its rather large grain structure.
Having the right filler metal (and controlling heat input and post-weld cooling) can help prevent cracking, as well as minimize the risk of losing corrosion resistance during the welding process.
