Latest Patents
Hirota's latest patents include an arc welding control method designed to mitigate issues such as air holes and spatters that often occur when welding zinc-coated steel plates. This method involves alternating between a short-circuit period and an arc period, with a significant increase in welding current at the detection of short circuit release. By ensuring that the increase gradient of the welding current is not less than 750 A/msec, the method effectively reduces the generation of defects during welding. Another significant patent focuses on improving the stability of arc welding by adjusting the inductance value related to welding output during the arc period. This innovation allows for stable arc welding with fewer spatters and greater resistance to disturbances.
