Abstract

The research results of the resistance to brittle fracture of the welded joint made by arc welding using Sv-08G1NМА wire made of a controllable rolling steel 10G2FB are presented. It was established that due to the high impact toughness of the weld, it was possible to provide satisfactory resistance to brittle fracture of the welded joint in the NS4 solution under cathodic polarization.
