Computer controlling hot-wire GTA all-Position tube welding sysetem

In this paper,a computer controlling hot-wire TIG(GTA) tube welding system is presented to raise the welding speed and quality,which fits the needs of the development of production.In this system,acr is taken as sensor,and automatic ad-justing of welding sequence and welding parameters,automatic tracking and demonstrating traeking of weld are reallized through the software.This system has following advan-tages:powerful anti-interference,high Preeision,quick response,good flexibility and small size,ete.It is fits of field operation,specially.
