IMPROVED METHODS FOR WELDING AGE HARDENABLE HIGH TEMPERATURE ALLOYS.
Abstract
Low melting filler wires, variations in base metal composition, and effects of prior material history were examined with respect to underbead cracking in A-286, with the latter being shown to be the controlling factor in cracking. Specimens were developed for evaluating strain age cracking propensity of different heats or different process treatments for sheet, bar, and plate material. Effects of long time-low temperature aging, pre heating, welding technique, peening, localized aging, and rate of heating on strain age cracking propensity were determined. (Author)
