The electron beam welding water-cooling plate is a crucial heat dissipation component in electron beam welding equipment. Made of highly thermally conductive metal, it has coolant channels inside. During welding, it can quickly absorb and carry away the large amount of heat generated by the focused electron beam, preventing the equipment from overheating, ensuring the stability and efficiency of the welding process, guaranteeing the quality of the welded parts, and prolonging the service life of the equipment.
