Abstract

The results of investigations of the mechanical properties of welded joints produced after cutting 09G2N steel by mechanical methods and by plasma torches of different design are presented. It is shown that the impact toughness and static bend strength of the welded joints, produced after plasma cutting without removing the zones of the thermal effect, are not inferior to the parameters obtained after mechanical cutting. In the application of the new single-circuit plasma torch for cutting metals prior to welding, it is possible to produce high-quality welded joints with high productivity and low energy consumption. © 2017 Informa UK Limited, trading as Taylor & Francis Group.
