摘要
简要介绍了一种防止T91／TP304钢管焊缝背面氧化的新技术,焊接工艺评定结果表明,使用背面防氧化焊剂代替氩气进行背面保护焊接T91和TP304钢管,可以得到金相、化学成分、机械性能及背面保护合格的焊接接头。
This paper briefly introduced a new type of technology for protecting back of the welding seam of T91/TP304 tube from being oxidized. Welding testing experiment showed that when welding T91 and TP304 , the welding flux can be used to take the place of argon backing gas with getting qualified welding joint in microstructure, chemical composition, mechanical properties and back protection.
