摘要
在对P92钢进行焊接的过程中,为了确保焊缝能获得良好的综合性能,需要对焊接速度、层间温度、内外壁温差等进行控制,同时在焊后进行中频热处理,进而在一定程度上为确保管道内外壁温度一致提供保证。
In the process of P92 steel welding, in order to ensure the welding to obtain good comprehensive performance, we need to control the welding speed, interpass temperature and the temperature difference between inside and outside wall, at the same time, take heat treatment after welding, in order to ensure the consistent temperature of the outer and inside wall in a certain extent.
