- 摘要:
- 通过焊接工艺评定试验确定了12Cr1MoV材质小口径管在不预热、不进行焊后热处理条件下的焊接工艺,用于锅炉改造工程中过热器的700余道接口的现场焊接,收到保证质量、降低成本和缩短施工工期的效果。
Welding process of non-preheating and non-PWHT on small diameter pipe of 12Cr1MoV steel is determined in accordance with welding process evaluation. It was used in in-situ welding of 700 joints of over heater for a boiler refit project. And the effect of quality guarantee, cost reduction and short work period were gained.1997,5(5): 18-19 收稿日期：1997-4-8参考文献：
