METHOD OF FUSION WELDING OF STEEL STRUCTURES AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: machine building.SUBSTANCE: invention relates to the machine building, and can be used during the fusion welding of the complex steel structures. Under the suggested method the welding is combined with heat treatment with use for this of the heating element in form of the ceramic pad-heated connected via the current switch to the welding power source. Besides, the device contains the electronic and bypass switches, programmable regulator, and thermoelectric converter located on the welded structures.EFFECT: invention reduces power consumption during post-welding heat treatment, increases strength and reliability of the critical welded structures.3 cl, 3 dwg
