FSW Cold Plates

Friction stir welded water cold plate: use a stirring head with a special shape of hard stirring finger to rotate and insert the welded body, and generate heat by friction with the welded body, through friction stir, and at the same time, combine the extrusion of the welding seam by the stirring head , The joint metal is in a plastic-melted state, the stirring finger moves forward along the welding direction while rotating, and a dense metal bond is formed under the combined action of heat and machine to realize the connection of materials.
