Title: The Innovative Contributions of Masuo Shibata
Introduction
Masuo Shibata is a renowned inventor based in Takarazuka, Japan, recognized for his innovative contributions to the field of welding technology. Holding three patents, he has significantly impacted manufacturing processes through his inventive solutions.
Latest Patents
Shibata's latest patents include an MAG arc welding apparatus and method, designed to achieve welding beads in a regular ripple pattern or in suitable sectional forms. The apparatus features a welding power source that generates two welding currents: a first current (I1) and a second current (I2), which is larger than the first. By switching between these currents, the wire melting speed can be altered, enhancing the welding process's efficiency.
The invention specifies that the first arc length generated is more than 2 mm, with the second arc length exceeding the first. The switching takes place at a frequency of 0.5 to 25 Hz, with the second to first welding currents' ratio maintained between 1.03 to 1.20. This innovative approach allows lap welding or butt welding to be performed effectively even in the presence of large gaps. The increase in the wire feeding rate by 5 to 20% yields a sufficient amount of molten metal, ensuring a visually appealing reinforcement.
