P92钢管在焊接修复过程中,目前国内均采用其匹配焊材进行焊接。在电厂临时性修复时没有匹配焊材的情况下,选用镍基焊材进行了P92钢管焊口修复试验,主要采用P92钢管现场施工用的焊接工艺进行焊接,热处理完成后选用镍基焊材进行修复。试验结果表明,用镍基焊材进行修复试验是可行的,但对于高温时效性能及持久强度性能,还需要进一步进行研究。 P92 pipe in the welding repair process, the current domestic use of their welding consumables for welding. In the temporary repair of power plants did not match the case of welding consumables, the use of nickel-based welding consumables P92 steel pipe weld repair test, the main use of P92 steel pipe welding welding process for construction site, after the completion of heat treatment using nickel-based welding consumables repair. The experimental results show that it is feasible to use Ni-based welding consumables to carry out the repairing test. However, further studies are required for the high temperature aging performance and long-term strength properties.
