Welding is used in radiator production to join components like fans, heat sinks, and condenser tubes into a complete structure. The process involves heating the welding material until it melts, then applying it to the workpiece surface, where it solidifies to form a strong joint. Common welding methods include manual welding, TIG welding, MIG welding, and laser welding, each with its advantages and disadvantages. The appropriate method is chosen based on the application. In radiator manufacturing, welding technology is crucial for ensuring stability and reliability under high temperatures and pressures, significantly impacting overall performance.
