Liquid phase diffusion welding method
专利汇可以提供Liquid phase diffusion welding method专利检索，专利查询，专利分析的服务。并且PURPOSE: To produce joints of homogenized compositions and good quality with good productivity by heating quickly the joining materials interposed with an insert material and holding the melted material at the welding temps. in succession until the insert material annihilates then subjecting the same to furnace heating.
CONSTITUTION: After an insert material 2 having a m.p. lower than that of joining materials 1, 1 is inserted between these materials, these are quickly heated through centralized high temp. heating by high frequency induction heating, resistance heating electron beam heating, laser heating or the like in a temp. elevation process I. As a result, the intert material 2 is melted surely in a large amt. In succession to this, these are held for an arbitrary time from the time II when the material 2 is completely melted until the time IV when the material 2 annihilates. Finally, these are subjected to ordinary furnace heating, and in this process V, the composition of the joint part is homogenized. In the process III, the molten atoms in the material 2 melted at a joining temp. α is diffused into the materials 1, 1.
