Abstract

The purpose of this paper is to describe the microstructure of welded joints produced by the Plasma+MAG method of S700 MC steel (high strength Re = 700 MPa). Welded joints of thermomechanical steel have been made with different values of heat input. The results of metallographic research of welded joints, microstructure, hardness distribution and impact toughness are presented. The weldability of S700MC steel in condition of hybrid Plasma + MAG is generally described.

Keywords: Plasma + MAG, hybrid welding, high strength steel
