Abstract
PURPOSE: To perform high efficient and high-quality high-frequency pulse TIG welding especially on Al, by using the bar (-) current between the base metal and welding torch as the high-frequency pulse current and the bar (-) current as the single pulse current in which the single pulse at every plural number of pulse number in the above-mentioned pulse current is inverted.
CONSTITUTION: In the welding current which is passed between welding base metal 6 composed especially of Al and welding torch 7 installed at the opposite side of base metal 6, bar minus current iSP is defined as a repeated high-frequency pulse current. On the other hand, bar plus current iRP is defined as the single pulse current in which one piece of pulse among 5W50 pieces pulse number of the above- mentioned high frequency pulse current is inverted, and thus the welding is performed. In this case, the current generated by constant-voltage regulated power supply 20 is transformed into a pulse by transistor bridge 21 and controlled as mentioned above. As the results of this, the bar minus current can perform a deep melting weldings of thick plate of Al as the high-frequency pulse current, and, on the other hand, a cleaning action can be performed by the inversion as mentioned above, and a high quality welding can be performed efficiently.
