摘要
为实现09Mn2VDG低温钢管首次在超大型液化气船上使用,对09Mn2VDG低温钢管开展GTAW+FCAW单面焊双面成型对接焊工艺研究。根据83 000m3 LPG船设计需要,结合09Mn2VDG低温钢管材特性,研究其焊接方法、焊接材料、焊接工艺参数。通过对焊接接头进行无损检测和各种力学试验验证,该焊接工艺满足船级社规范要求。经实船使用,该工艺质量稳定,经济效益显著。
In order to realize the first application of 09 Mn2 VDGD low-temperature carbon pipes on VLGC,the one-side welding both sides formation process of GTAW ＋FCAW is studied.According to the 83 000 m3 LPG carrier and the characteristics of 09 Mn2 VDGD lowtemperature pipes,the welding methods,welding material and welding parameters are studied.The non-destructive test of welded joints and mechanical test are completed,which showes that the welding procedure meets the requirements of classification society.The quality of the process is stable and has good economic benefit in actual use.
