摘要： There is provided a tool for friction stir welding, in which a coating layer is less likely to peel off from a base material and excellent wear resistance is achieved. The tool for friction stir welding according to the present invention includes a base material (BM) and a coating layer. The BM includes a first hard phase (FP) formed by WC particles, a second hard phase (SP) and a binder phase (BP). The SP is formed by a compound of one or more metals selected from Ti, Zr, Hf, Nb, Ta, Cr, Mo, and W and one or more elements selected from nitrogen, carbon, boron, and oxygen, and is included in the BM at a volume ratio of 3% to 30%. The BP is included in the BM at a volume ratio of 8% to 28%. The FP is higher than the SP in terms of volume ratio.

摘要： In a first step, friction stir welding is performed, while supplying a filler into a joining portion, in order to prevent the coarsening of crystal grains of metal materials in a subsequent fusion processing. Then, a fusion processing such as MIG welding is performed. The filler to be added to the joining portion includes a substance that does not chemically react with the metal materials and has a melting point higher than a melting point of the metal materials and a substance in which a misfit with the metal materials is within ±15%. As a result, the coarsening of crystal grains by the fusion processing is inhibited and the joint strength can be increased.
