ABSTRACT:
When a welded joint is produced for joining metal components by applying a plurality of layers of deposited metal, the plurality of layers of deposited metal are provided in a groove of a weld preparation formed between the metal components to be joined in such a manner that each layer of deposited metal has a small thickness and a large width crosswise of the groove and the layers are arranged to be superposed one over another. During this process, a coarse metal structure formed when each underlying layer of deposited metal is provided is completely tempered and transformed into a fine metal structure by the heat generated when each overlying layer of deposited metal is provided. Thus the welded joint produced by this method shows an excellent performance in service.
