采用ＰＣ机对全位置管焊机进行控制，从而实现了焊接过程的实时控制，保证了焊接电流的反馈调节及电弧电压的自动调节。并能够实现焊接小车机头的横向摆动及焊接参数的顺序调整。经过实验验证，焊接过程稳定、焊缝质量较好，具有一定的实用价值。
Using PC to control all-position tube welding machine, so as to realize the real-time control of welding process, to ensure the welding current feedback regulation and arc voltage automatic adjustment. And can achieve the welding car head horizontal swing and welding parameters of the order of adjustment. After experimental verification, the welding process is stable, the weld quality is good, has a certain practical value.
