Latest Patents
His latest patents include:
1. **Flux-cored wire for use in gas-shielded arc welding** - This invention involves a flux-cored wire designed for use in gas-shielded arc welding. The flux, which consists of a specific composition (measured in weight %), is inserted as the core of a metallic casing. A notable feature of this invention is the controlled hydrogen content within the wire, which is defined as 15 ppm ≤ H ≤ 139 + 440F ppm, where F denotes the weight % of fluorine with respect to the entire wire.
2. **Method and apparatus for non-consumable electrode type automatic arc** - Arai's second patent is a method and apparatus for non-consumable electrode type automatic arc welding. This innovative design allows for the automatic control of the arc length produced between a non-consumable electrode and the workpiece being welded. The adjustment is achieved using an electric drive motor, which operates based on signals that proportionally integrate or multiply the voltage difference between the detected arc voltage and a set reference voltage.
