Introduction of Friction Stir Welding and Its Application to Aluminum Rolling Stock
마찰교반용접의 현황 및 알루미늄 철도차량에의 적용
Abstract
MIG or TIG welding has been the most popular welding process for joining aluminum alloy structures. However, porosity, hot crack and distortion were serious problems in inert gas fusion welding. Since FSW(Friction Stir Welding) was invented by TWI in 1991, it has been the powerful candidate for solving the problems of inert gas welding. In this paper, the principle and characteristics of FSW is introduced and its application to rolling stocks is presented to make basis for future development in production technology of aluminum rolling Stocks.
