Abstract
PURPOSE: To exactly bond the base metal of parts to a deposited layer by specifying a preheat temp. of a part and a deposition rate of a bead in forming a welding deposition bead of steel on a preheated part surface. CONSTITUTION: Parts are preheated, a steel having a temp. Ms lower than the preheat temp. is deposited on a surface to be repaired of a preheated part, this layer is air cooled to a temp. of the preheated part to conduct repair. In this method, the part is preheated to a temp. higher than the temp. Ms of the base metal of the parts, a min preheat temp. is 300 deg.C. Further, the deposit rate is set so as to heat respective three beds or more deposited beforehand to a temp. higher than a temp. A1 of the substrate metal of the parts and a temp. lower than a temp. Tsol . By this method, high uniformity of the strength property of the deposited layer is not affected, the reliable bonding between a repair surface and the deposited layer of steel parts of a roll, etc., is secured.
