Abstract

The paper presents the technology of MAG welding of the tram switch of butt joint of tramrail 54G2 (W.N.1.0623, group 11.3) to a block of Cogidure (W.N.1.8715, group 3.2) using a solid wire and a copper backing. In addition, an overview of nondestructive testing of the welded joint is given (VT, PT, UT), as well as macrostructure and hardness was given. Two qualification tests were performed, one of which passed the fracture test with variable load and frequency, and the other passed the macrotest.
