摘要
Abstract
This paper systematically analyzed and test the cracks of tubesheets-tube of the synthesis loop steam generator in a shopwork.The results show that the incomplete fusion of protection tube to tube and the structure defects of protection tube are the main cause of welding cracks,and put forward the corresponding prevention measures.关键词
