【摘要】 本文介绍了新开发的微机控制热丝钨极氩弧焊（ＧＴＡ）焊管系统，旨在提高焊接速度及质量以适应生产发展的需要。控制系统利用焊接电弧为传感器，通过软件来实现焊接程序、焊接规范的自动变换、焊接多数的自动控制以及焊缝的自动跟踪和示教跟踪。具有抗干扰性强、精度高、反应快、柔性强及体积小等优点，特别适合于野外现场施工。更多还原

【Abstract】 In this paper,a computer controlling hot-wire TIG(GTA) tube welding sys-tem is p resented to raise the welding speed and quality,which fits the needs of thedevelopment of production. In this system,arc is taken as sensor,and automatic ad-justing of welding sequence and welding parameters,automatic tracking and demonstratingtracking of weld are reallzed through the software,This system has following advan-tages:powerful anti-interference, high precision,quick response,good flexibility andsmall size,etc. It is fits of field operation,speeially.更多还原
