This is due to the higher standards of quality, service conditions, structural complexity, and the use of new materials. Therefore, more and more it becomes necessary to introduce new processes to get a quality and reliable connection.The experiments on the sample connection of low carbon steel (stal20) and medium-steel (30HGSA) methods MIG-welding, MIG-brazing and MIG-process with low heat input ("cold curve"). Investigated the macro-, micro-and chemical heterogeneity of butt joints.Found that use of MIG-process with low heat input ("cold curve") can significantly reduce the heat input into the joint virtually eliminate splashing, more uniform heating of the HAZ metal in depth articles, reduce land area fusion welding, to reduce the grain size in the HAZ.Mechanical tests conducted on samples of steel 30 HGSA showed that the type of soldering process (MIG and "cold curve") and the size of the gap has little effect on the bond strength, which is - 400 ... 420 MPa.
