【摘要】 本文通过模拟ＢＨＷ－３５与２０ＭｎＭｏ焊接过程，分析和研究４２ＣｒＭｏ钢的焊接特性，分析焊缝的力学性能和金相组织，认为４２ＣｒＭｏ与ＢＨＷ－３５焊缝各方面性能满足原ＢＨＷ—３５和２０ＭｎＭｏ焊缝设计要求，从而使电厂按期运行。更多还原

【Abstract】 Welding characteristic of 42CrMo steel and its mechanics performance and metallographic Composition of welding seam had been analyzed and investigated by modelling welding process of BHW-- 35 and 20MnMo. It had been considered that various performances of 42CrMo and BHW-- 35 can satisfy the original design requirements of BHW-- 35 and 20MnMo seam,thereby the power plant can be operated in time.更多还原
