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.
Keywords: high-strength steel, argon-arc gap welding, hardness, impact toughness, structure, weld metal, heat affected zone |
