Resumen
Welding materials, which are as a rule used for making the responsible metal constructions, do not always meet the high indices of rolled steel properties of durability classes ?355-490 MPa. In the paper the research results of application of welding materials produced by the firm «ESAB» for the automatic flux welding of rolled steel 06?2? ?? ? 27.1-05416923-085:2006 are presented.
