Abstract: A welding method for manufacturing a heat sink has the following steps in sequence: removing rust from a first workpiece and a second workpiece, degreasing the first workpiece and the second workpiece, increasing surface roughness of the first workpiece and the second workpiece, performing a copper supersonic cold spray step to the first workpiece and the second workpiece, and then combining the first workpiece and the second workpiece via welding. With the copper supersonic cold spray step and the surface treatment steps before the copper supersonic cold spray step (i.e. rust removal and degreasing, and surface roughness increasing), the solder can be attached to the workpiece tightly in the combining via welding. Thus, the welded workpieces are combined firmly and not be separated easily. If a heat sink component is made through welding workpieces in the welding method, the heat sink component has higher strength and cannot be destroyed easily.
