Title: Hiroyuki Homma: Innovator in Metal Production Techniques

Introduction

Hiroyuki Homma is a distinguished inventor based in Isehara, Japan. He has made significant contributions to the field of metal production, holding a total of 2 patents. His innovative methods have advanced the techniques used in clad metal production and submerged-arc welding.

Latest Patents

Hiroyuki Homma's latest patents include a method of producing clad metal and a method for submerged-arc welding a very low carbon steel. The method of producing clad metal involves forming a cladding on the surface of a metal substrate by subjecting powder of a different type of metal to hot isostatic pressing. This process occurs under a gas pressure load of not less than 300 Kg/cm² at a temperature not higher than the solidus, resulting in a composite material that can be elongated by hot working. Additionally, the composite material may undergo soaking or solution treatment before hot working. His second patent focuses on producing line pipe of high strength and high toughness through the submerged-arc welding process. This method utilizes a welding wire containing 0.18-0.55% carbon, with the addition of titanium or boron, and involves welding a steel containing 0.005-0.06% carbon.
