| Abstract: | As for "D6A" super-strength steel ,we analyzed its weldability and cracking sensibility, and used TIG welding process to weld thick-wall shell. The weld crack was avoided by means of adopting reasonable technical measures and postweld heat treatment process. In result, the welding quality and the mechanical properties of the welded joint are satisfying |
