摘要
振动埋弧焊工艺是一种在焊接过程中通过给焊件施加振动来改善焊接性能的新工艺。介绍了在西气东输阀门焊接中运用振动埋弧焊进行厚板焊接的试验,就残余应力、焊接变形、金相三个方面对常规埋弧焊和振动埋弧焊工艺进行比较,对振动埋弧焊工艺进行初步探讨。试验结果表明,振动埋弧焊工艺能有效地降低焊接残余应力和变形,并细化晶粒。
Vibratory submerged arc welding is a new welding process to improve welding quality by applying vibration on plate. The test of thick plate welding using vibratory welding of valve in west-to-east gas pipeline project was introduced, and then normal welding was compared with vibratory submerged arc welding in residual stress, distortion and microstructures. The results of test showed that vibratory submerged arc welding can reduce residual stress and distortion notably and make the grains fine.
