Abstract
The electro chemical buffing stainless steel is used for the equipment and the pipes in the manufacturing process of the semiconductors, vacuum chambers, foods, and medical. Welding is necessary when assembling the manufacturing equipment, but oxidation and fume adhering which arise near the welding line cause a remarkable drop in surface smoothness and corrosion resistance.
We are developing the Oxidation-Control and Fume-Free Welding Technology for the vessels of manufacturing equipment.
In this paper, we reported the Oxidation-Control TIG Welding Method in the welding chamber in which atmosphere is controlled. And then, the reduction of the amount of fume and the Fume-Free TIG Welding Method using fume suction nozzle in the welding chamber is reported.
