Abstract:
A method for making a welded joint, comprising the steps of:resistance spot welding an intermediate element to an edge of one of pieces welded, said intermediate element being made of the same metal as that of the welded pieces,argon-arc welding the pieces together with the intermediate element with argon being fed to a weld produced, wherein said intermediate element is covered with a layer of chromium before the welding, the welded pieces are fit up with the intermediate element positioned therebetween by tacking the pieces using a manual argon-arc welding with a nonconsumable electrode on a weld backing of the same metal as that of the pieces, said argon-arc welding being made by two runs of a nonconsumable electrode at transverse oscillations of the electrode relative to said weld,keeping said weld backing after welding.
