    • 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.
    • 当通过施加多层沉积金属制造用于接合金属部件的焊接接头时,多个沉积金属层被设置在形成在要接合的金属部件之间的焊接制品的槽中, 沉积金属层具有小的厚度和大的横向宽度的沟槽,并且这些层被布置成彼此重叠。 在该过程中,当提供沉积金属的每个下层时形成的粗金属结构被完全回火,并且当提供每个沉积金属的上覆层时产生的热量将其转化为细金属结构。 因此,通过该方法制造的焊接接头表现出优异的使用性能。
