<p><P>PROBLEM TO BE SOLVED: To provide a built-up welding method by which the built-up welding can be executed in arbitrary thickness, a smooth built-up surface can be obtained, and which can reduce the number of machining stages and is highly efficient. <P>SOLUTION: The built-up welding method is constituted in such a manner that the outside surface 2a of a surface forming material 2 is located from a built-up surface 1a of a base material to execute the built-up welding to a position of built-up thickness and the welding is executed so as to fill a filler metal 4 between the built-up surface 1a and the inside surface 2b of the surface forming material 2, the built-up thickness can be arbitrary set by aligning, positioning, and installing the position of the outside surface 2a of the surface forming material 2 and the built-up thickness, as a result, additional built-up welding is not required for finish machining contrary to a conventional way, the number of stages for welding and machining can be remarkably reduced and the built-up welding with excellent efficiency can be executed. And also, the built-up welding of a material different from the base material is possible, the built-up welding in which the materials are different in a first layer and a second layer to the built-up surface can be executed without a complicated work such as a change of the filler metal in the middle, and excellent efficiency can be achieved. <P>COPYRIGHT: (C)2003,JPO</p> |
