Title Hybrid heat source friction stud welding technology research
Abstract
According to melting welding method can arose porosity, crack, partial and fusion welding defects ，steel could be welded with methods of hybrid heat resource friction stud welding, combined induction heat source WH-VI-50 Induces power with a drilling machine which works as friction power. Preheating workpiece can effectively reduce the power of the friction motor, light-duty of the welding equipment. The higher the temperature of induction heat, the less heat of friction would provide and the smaller the motor would be.
The material in use is Q235 steels for research which has good weldability. The test is about sheet or bar and studs （solid or hollow）. A lot of tests have been done to research and analysis the parameters such as rotating speed ，heating temperature, protectants which effect on the strength of the welding joints. In order to analysis the welding joint microstructure，scanning electron microscopy and tensile tests have been done.
Keywords ：hybrid heat resource induction heating friction studs welding joint strength
