Microstructure analysis of 1Cr17Mn6Ni5N and Q235 heterogeneous steel welded joint

Zhixin Wang

Abstract

The pearlitic steel Q235 and the austenite steel 1Cr17Mn6Ni5N were welded by the plasma arc welding. By optical microscopy and scanning electron microscopy, the microstructure of joint was observed, and its micro-hardness was tested with micro-hardness testing. Finally, the weld fracture was observed. The results showed that the welding zone between pearlite steel and austenitic steel formed the martensite and the carbon migration was found at the two sides of joint.
