The invention discloses a bimetal-material circular saw. The bimetal-material circular saw comprises a substrate and a high-speed steel belt, the substrate is in a round disc shape, the high-speed steel belt is in a round ring shape, saw teeth are arranged at the outer edge of the high-speed steel belt, triangular tooth structures distributed evenly along the periphery are arranged between the outer edge of the substrate and the inner edge of the high-speed steel belt, the triangular teeth of the outer edge of the substrate and the inner edge of the high-speed steel belt are meshed with one another, and the welding length of the outer edge of the substrate and the inner edge of the high-speed steel belt is increased so that the welding strength is increased. A manufacturing method comprises the steps that heat treatment and leveling processes are conducted on the substrate and the high-speed steel belt, the substrate and the high-speed steel belt are welded, and finally, local sensingheating treatment is cond
