To provide a build-up welding method and a device capable of forming a base material in an excellent shape by build-up welding with a filling welding material.
A filling welding material 300 is build-up welded at a surface welded position 211 of a phase transformation base material 200, and a build-up welded part of the phase transformation base material 200 with a filling welding material 300 is heated from a base material rear face 220 up to a phase transformation temperature. Even when welding deformation such as vertical shrinkage or vertical bending deformation, shrinkage strain or the like generates in the surface welded position 211 build-up welded with the filling welding material 300 or the build-up welded phase transformation base material 200, the welding deformation, the shrinkage strain or the like is canceled and relaxed due to expansion strain caused by phase transformation of the base material rear face side 220 of the phase transformation base material 200 by heating the part of the phase transformation base material 200 build-up welded with the filling welding material 300 up to the phase transformation temperature.
