    摘要: The outer surface of a butt-welded joint is build-up welded such that a ratio h/t is higher than approximate 0.2 and a ratio L/.sqroot.Rt is higher than approximate 1, where h denotes height of a build-up welded portion; t, wall thickness of a pipe; L, width of the build-up welded portion; and R, radius of the pipe. As a result, the residual stresses in the build-up welded portion counterbalances the residual stresses in the welded joint, whereby the residual stresses at the inner surface of the welded joint can be relieved.

    摘要: A printed wiring board and a method for manufacturing the printed wiring board in which widths of a first and a second circuit are close to each other and substantial miniaturization can be achieved. In order to achieve this object, a first circuit and a second circuit having different thicknesses are formed in the same reference plane by etching a metal-clad laminate including a conductive layer and an insulating layer. The thicker of the circuits has a clad-like configuration in which three layers, a first copper layer/a different kind of metal layer/a second copper layer, are sequentially stacked. The manufacture of the printed wiring board includes a clad composite material in which three layers of a first copper layer/a different kind of metal layer/a second copper layer are sequentially stacked as a start material, and selective etching characteristics between the layers are utilized.
