Method for making a welded joint

摘要

The invention relates to the field of welding, more particularly, to methods of making welded joints for pieces of maraging steels, and may be used in different branches of machine building.Before welding, an intermediate element is resistance spot welded to one of the welded edges. The element is made of the product's material and covered with a layer of chromium. The joint is fit up by tacks on a weld backing made of the same material as the product. The tacks are made by a manual argon-arc welding by a nonconsumable electrode. The joint is argon-arc welded by two runs of a nonconsumable electrode at transverse oscillations of the same.
