摘　　要：对D6A超高强钢作了焊接性估算及裂纹敏感机理分析。采用手工钨极氩弧焊方法 ,选择了合适的焊材 ,采取了有效的工艺措施 ,制定了合理的焊后热处理工艺 ,解决了D6A钢焊缝易开裂的问题。焊缝质量优良 ,综合性能良好 ,强度约为 1 0 30MPa ,塑。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
