AbstractThe detecting device has a metal detector installed in the place near the nozzle of welding torch and at the same height as the nozzle. After the power supply of the detecting device is turned on, if some current flows through the resistor, the plasma arc is shown to not penetrate the workpiece completely; and if no current, the plasma arc is shown to penetrate the workpiece completely. The present invention makes it possible to detect the formation process of plasma arc welding "small hole" from the front side. |
