Abstract

A literature review and own investigations of the impact of a welding kind and post-welding thermal treatment upon a phase structure and residual stresses of welded joints are carried out. It is defined that such high-performance and promising welding kinds as electronic-beam welding (EBW) and laser welding (LW) have a negative impact upon a phase structure of two-phase (duplex) and single-phase steels as a result of high cooling rates of welded joints.
