| 摘 要： | 常规的高能束焊接方法因焊后冷速较快易导致双相不锈钢焊缝及热影响区两相比例失衡,接头性能恶化.采用激光-MIG复合焊接方法对2205双相不锈钢进行焊接,焊后对接头微观组织、力学性能和腐蚀性能分析发现,焊缝及热影响区铁素体相比例控制在40%～70%合理范围内,接头硬度和抗拉强度高于母材,焊缝、熔合线、热影响区的～40℃冲击...

| Abstract: | Phase ratio in weld metal and heat affected zone of duplex stainless steel will be unbalanced and joint properties deteriorated because of fast cooling rate after welding by conventional high energy density beam,so the duplex stainless steel 2205 is welded by using laser-MIG hybrid welding method,and the microstructure,mechanical property and corrosive property of welded joint are analyzed.The results show that the phase ratio of ferrite in weld metal and heat-affected zone is controlled between 40%-70%,the... |
