STUD WELDING FOR ALUMINUM ROLLED PRODUCT BY ARC AND FRICTION WELDERS

摘要

The weight reduction of transport means such as automobile, rolling stock and ship have been permiating gradually to meet the requirements of reducing the fuel consumption, improving the capability and adding new functions. Now its facing new millennium, big discussions have arison about the global environmental disruption of the earth. It is getting more important for all nations to endeavoure in maintaining the good environmental condition along with the globalization of the industries, and the tendency of the weight reduction of the vehicles is intensified very much since it is one of the effective countermeasures. For instance, aluminum diecasting and cast alloy have been used for automotive parts except body, but rolled products are also expected to be used for the body. Nippon Stud Welding Co., Ltd. has been developing the aluminum stud welding technology for rolled products through the experience of stud welding for LNG storage tanks made of aluminum alloy. Aluminum studs of ? 6 to the thin sheet from 1 to 3 m/m in thickness were experimentally welded by using the arc welder and a friction welder. The outline of the results are described in this paper.
