Abstract:

Hardness, impact toughness, and structure of slot gap welds (TIG) of low alloyed steel with the ensured yield stress of 890 MPa have been investigated. According to obtained results, the considered technological procedure provides equal strength of the weld and base metals as well as appropriate cold resistance.
