LIQUID PHASE DIFFUSION WELDING METHOD FOR METALLIC MACHINE PART AND METALLIC MACHINE PART |
摘要 |
A liquid phase diffusion welding method for a metallic part capable of increasing the quality and productivity of a joint part by achieving the shortage of welding time, the uniformization of welding structure, and increases in the tensile strength and fatigue strength of a joint to increase the quality and reliability thereof. An amorphous alloy foil for liquid phase diffused welding is disposed on the fusion face of a metal material. As a primary welding, the amorphous alloy foil and the metal material are fused and press-welded to each other by a resistance welding to form the joint part. As a second welding, the joint part is re-heated to the melting point of the amorphous alloy foil or higher and then the temperature is maintained until the solidification of the joint part is completed. |
