FIELD: machine engineering, possibly manufacture of non-detachable parts of steels and alloys. ^ SUBSTANCE: method is realized due to using electrode with heat resistant insert extending outside electrode base. Method comprises steps of selecting length of insert extension depending upon thickness and properties of material of thin part; placing welded parts between electrodes in such a way that electrode with insert is at side of thin part; at welding process deforming thin part according to length of insert extension for forming relief and making welded joint in deformation zone. At beginning of welding process thin part is deformed and surface area of mutual contact of parts is significantly reduced and increased density of welding electric current is provided. Heat concentration in zone of mutual touching of parts increases till fusion for providing welded joint. ^ EFFECT: simplified welding process of enhanced efficiency and lowered labor consumption. ^ 2 cl, 4 dwg |
