「In the welding and cutting field, the company established dissimilar-metal joining technology for copper and stainless steel. It is advancing proposals to the air-conditioning industry and other sectors to reduce the use of expensive copper.」
For copper and stainless-steel welding technology, the company progressed from aiming to establish a mass-production system to establishing dissimilar-metal joining technology and making proposals to customers. - FY2024-Q2First statedAnnual report
「In its Materials business, the company independently developed welding technology for copper and stainless steel using copper-iron alloy filler metal to reduce the use and cost of copper, whose price has risen sharply. This makes it possible to replace some of the copper used in refrigerant piping and other applications in the air-conditioning industry with stainless steel, which has greater price stability. The company aims to establish a mass-production system jointly with filler-metal manufacturers and supply the product to the market.」
