Use of electroslag welding in forging-and-swaging manufacture

The results of the experiments on electroslag welding (ESW) of large-scale products made of stamp steels are given. A technology is developed for achieving welding seams with properties closely similar to the properties of the basic metal. The best complex of mechanical characteristics of the welding seam metal with stamp steels ESW is achieved after a thermal treatment according to the scheme: normalization-hardening-tempering. The application of ESW with a fusible mouthpiece on intermediate products made of 5KhNM type stamp steel with thermal after-treatment will allow producing stamp cubes of practically unlimited size
