We are currently experienced in Friction Stir Welding, Friction Stir Welding Service, Internal Water Cooling, Welding Equipment, Stir Welding, etc., and have received and successfully completed delivery of a large number of orders. Stir friction welding is a solid-state welding process that involves rotating and moving a tool along a joint line to generate friction and heat that softens the material and causes the two parts to melt locally, thereby joining the parts together without adding metal. Stir friction welding welding process is by a cylinder or other shapes (such as with threaded cylinder) stirring needle (welding pin) into the joints of the workpiece, through the high-speed rotation of the welding head, so that it is friction with the welded workpiece material, so that the temperature of the material in the connection part of the material to soften. At the same time, the material is stirred and rubbed to complete the welding.
