Latest Patents
Ichikawa holds a patent for a gas-shielded AC arc welding method and machine that utilizes a consumable electrode. The patent describes a process where an EP output voltage is set to ensure that the welding current remains equal to or lower than a critical current level. Additionally, the EN output voltage is maintained at a level lower than the EP output voltage. This innovative approach allows for a consistent wire melting rate during both EP and EN polarity periods. Even in cases of short arc lengths that typically lead to frequent short circuits, this method enables stable gas-shielded AC arc welding. The technology allows for high wire melting rates, shallow penetration, and convex weld reinforcement, which can be tailored to specific applications.
