Introduction

Yasuo Murakami is a notable inventor based in Hikari, Japan. He has made significant contributions to the field of welding technology, holding a total of 2 patents. His innovative methods and apparatus have advanced the capabilities of welding processes, particularly for nickel and nickel alloy products.

Latest Patents

Murakami's latest patents include a method of welding nickel or nickel alloy products. This method involves generating an arc between the products to be welded, with a tungsten electrode serving as a negative pole. A shielding gas, consisting of an argon-based mixed gas containing hydrogen and/or helium, is emitted from a nozzle, confining the arc's apparent flaring angle within 80 degrees. The welding torch is moved along the weld line while feeding a filler wire into the molten pool directly below the arc.

Another significant patent is an automatic welding apparatus designed for non-consumable-electrode-type arc welding. This apparatus features a mechanism that feeds a second wire into the molten pool, oscillating in synchronism with the welding torch. Additionally, it includes a mechanism for consumable-electrode-type arc welding, which also feeds a second wire in a similar manner.
