摘要
药芯焊丝富氩混合气体保护焊是一种高效的焊接工艺,文中进行了A333 Gr.6+E71T-1MH8富氩混合气体保护焊工艺试验并测试了焊接接头的力学性能,分析了该工艺焊接过程中易出现的缺陷,制定了有效的防止措施。试验结果表明,该工艺适用于场站的大直径厚壁管道焊接。
Flux cored wire and mixed gas rich argon shielding arc welding was a highly efficient welding process.A333 Gr.6 + E71T - 1MH8 rich argon mixed gas shielded arc welding process experiments were carried out,and the mechanical properties of welded joints were tested. The defects easily appeared in the welding process were analyzed,and the effective prevention measures were developed.The results showed that the welding process is suitable for large diameter thick-walled pipe of the station.
