| Abstract: | In this paper,the weldability of the outer conductor with co-axial cable made of 0.25mm thick band copper is analyzed by using the TIG welding process with low frequency pulse current.Through numbrs of tests for welding technology,the results show that the authors have successfully controlled the formation of weld,and obtained the high quality welded joint which is able to satisfy the technical requirements in production.This paper discusses that the key problem to weld band copper with a thickness of 0.25mm is to control the appearence of edge weld and the performance of welded joint,and,especially,the role of heat dissipation on the clamping apparatus should be taken into consideration.Besides,a method to obtain a form of rectanglar pulse-waves the ZXG-120 rectifier power source is also presented in this paper. |
