| 摘 要： | 进行了基于微束等离子弧的焊缝跟踪传感可行性研究。利用微束等离子弧发生器产生非转移等离子弧，测量喷嘴与工件之间的等离子焰流的等效电阻，试验发现，该等效电阻与喷嘴距工件的高度之间有明确的对应关系，配合适当的扫描装置，可实现焊缝位置检测功能。进行厂维弧电流、喷嘴结构、电极直径、离子气流量等参数对该等效电阻的影响试验，为这种传感方式在实际应用中的各参数选择，提供了试验依据。

| Abstract: | In this paper, weld seam tracking method based on microbeam plasma arc is developed. A nontransferred plasma arc was setup by a micro-beam plasma generator, then the plasma flame resistance between the nozzle and the workpiece was measured. Results show that, there is a clear relationship between the resistance and the torch height. If a scan set is equipped, the weld seam position can be detected. Fundamental experiments were done to show the influences on the resistance by sustained arc current, nozzle structure, electrode diameter, and plasma gas flow etc. |
