In order to solve the problem of thermal deformation of brazed saw blade substrate under high temperature, the temperature, the microstructure and the stress-strain field of local induction brazed saw blade substrate were analyzed with the finite element software, and the factors affecting the deformation of saw blade substrate were studied. The results show that the phase transformation of the saw blade substrate is mainly distributed on the brazing working surface. After cooling to room temperature, three microstructures including ferrite, pearlite, bainite and trace martensite are obtained. When the scanning speed of the heat source increases, the deformation and the residual stress of the substrate increase. When the scanning speed increases from 0.25 mm/s to 2.00 mm/s, the thickness of the phase change layer decreases from 5.8 mm to 4.7 mm, the maximum deformation increases from 0.41 mm to 0.82 mm, and the residual stress increases from 482 MPa to 667 MPa. The test results are basically consistent with the simulation results.
