DISSIMILAR WELDING METHOD USING HYBRID FRICTION STIR WELDING SYSTEM

摘要

PURPOSE: A method of welding a different kind of materials using a hybrid FSW(Friction Stir Welding) system is provided to generate the sufficient plastic flow of and light alloy and a steel material by practicing TIG preheating at a steel-material welding unit when a different kind of materials, light alloy and a steel material, are welded. CONSTITUTION: A FSW tool(104) makes contact with the boundary line of first and second bases(101,102), rotates and performs welding. A TIG torch preheats a steel material of the welded unit of a different kind of materials. The bases make contact with each other to form a welded unit(103). The FSW tool is fixed to the spindle(105) of a hybrid FSW system(100). The spindle is connected to the driving shaft of a driving motor to set the number of rotation.
