[0002] During the welding process of forklift parts, a lot of high temperature will be generated on the surface of the welded parts, and large parts need to be cooled after welding. Water cooling equipment may be needed to quickly reduce the temperature of the welded parts. This method can effectively prevent overheating and thermal deformation, and improve process controllability and production efficiency.
