A study of the arc welding seam tracking control system for eliminating interference of tack weld

抑制 点 固 焊道干扰的弧焊跟踪控制系统的研究

Besides centering and tack welding by laser beam should be avoided as centering point and tack-welding point can influence weld quality largely .

但 焊缝质量受激光对中点和 点焊点的影响很大，应尽量避免采用激光对中及点焊。

The problems of influences of edge displacement disturbance tack weld disturbance and high arc temperature on the sensor have been solved .

在传感器方面解决了错边干扰、位 焊点干扰及电弧高温的影响。
