摘要
分析了尾管在使用状态下产生裂纹及补焊后重新产生裂纹的原因,采用改善受力状态、预制反向应力等措施,配合合理的补焊工艺,成功地修复了断裂的尾管。
How to prevent and stop the cracking from the repair welding process of castiron pieces is approached in the paper. From fracture mechanics principle,the analysis is carried out to put forward the concrete procedure, and some repair welding examples are presented, too.
