摘要
对压力容器不等厚焊口的典型开裂焊口进行焊接工艺、焊后热处理、应力分析,并提出改进措施,最后进行理化、无损检测验收。
The typical cracked welded junction of unequal thickness welded junction of pressure vessel is analyzed by welding process,post weld heat treatment and stress,and the improvement measures are put forward.Finally,the physical,chemical and nondestructive testing acceptance is carried out.
