FRICTION WELDING METHOD AND APPARATUS FOR BULK METALLIC GLASS

摘要

The present invention relates to a friction welding method and apparatus for a bulk amorphous metal material,;A step of biting and fixing the rotating side metal member m1 to the rotary chuck 12-1, biting the pressing side metal member m2 to the pneumatic gripper 13-1, and applying and fixing air pressure to the control unit 18 Setting and inputting a working condition to computer equipment 18-1 on the crankshaft, rotating the chuck 12-1 and the rotating side metal material m1 at a constant speed, and the pneumatic gripper 13-1) to linearly move and pressurize the pressurized side metal material m2 toward the rotating side metal material m1 and pressurize the air pressure on the pneumatic gripper 13-1 to the completion of welding due to the pressurization. By providing a friction welding method comprising the step of releasing and stopping the rotation of the spindle on the drive unit 12 and the friction welding apparatus for its implementation,;In the case of friction welding of specific materials such as bulk amorphous metal materials, very high bond strength can be obtained. As a result, it is expected to increase the workability of bulk amorphous metal materials having excellent mechanical and thermal properties and to greatly expand the application range. .;Bulk amorphous metal, friction welding.
