摘要
大型不锈钢封头需要先钢板拼接,然后经冷旋压成形。对冷旋压成形后在焊缝上出现大量裂纹的原因进行分析,并制定了相应的防止措施。
The steel plates should be butted, and then shaped by cold spinning to form large stainless steel heads. Analyzes reasons of a large number of cracks in welds after cold spinning forming, and puts forward corresponding prevention measures.
