一种铸钢焊接返修件的高温检测方法

摘要

I the light of both weldability of ZG12Cr9Mo1CoNiVNbNB steel and welding technology for steel castings, in conjunction with high-temperature detecting technology for steel castings, a high-temperature detecting method and lfowsheet were developed, thus shortening period of repairing steel castings by welding, reducing heat treatment cost of steel castings.%根据ZG12Cr9Mo1CoNiVNbNB钢的焊接特性和铸钢件的焊接工艺，结合铸钢件的高温检测方法，形成了一种焊接返修的铸钢件高温检测方法和流程，可缩短铸钢件焊接返修周期，降低铸钢件的热处理成本。
