Welding Procedures and Post Weld Heat Treatment

2022
All of the weld processes described in Chapter 7 are capable of producing high quality welds. As further described in that chapter, some processes are limited either by the process itself, or for practical reasons, to the production of certain types of welds. Regardless of the weld process or type, numerous variables affect weld quality.

Post-weld heat-treatment cracking in superalloys

International Metals Reviews, 1983
This review is concerned with a type of cracking that often occurs during the postweld heat-treatment of Ni-base superalloys. The metallurgical factors and process variables that influence crack sensitivity are discussed in detail. The various types of tests available to study this type of embrittlement and the limitations of each approach are briefly ...
