Effects of stress relief coupled with reduced EBW energy on flow formed maraging steel weldment
Source abstract
Abstract
A flow formed C-250 maraging steel tubing was welded by electron beam welded (EBW) process and subsequently age hardened. Conventional EB welding with high energy input had resulted in seriously inadequate percentage elongation of the weldment. With an additional prewelding stress relief treatment and EBW with a lower energy input, the elongation of the weldment showed significant improvement after being treated with age hardening. It was found that the tensile strength was increased by 12% and the percentage elongation was remarkably increased by 92%.
