针对12Cr1MoV小口径钢管焊接问题,提出了采用全氩弧焊,并结合焊前预热和焊后热处理的焊接工艺。实践证明,采用这种焊接工艺进行焊接,可以获得质量优良的焊缝,保证高温过热器的安全运行。
Aiming at the problem of 12Cr1MoV small-diameter steel pipe welding, a welding process using all-argon arc welding and combining with pre-welding and post-weld heat treatment was proposed. Practice has proved that using this welding process for welding, you can get good quality weld to ensure the safe operation of high temperature superheater.
