Masahiro Hasegawa is a Production Engineer with 13 years’ experience specializing in welding technologies and production support for stainless steel (SUS) railway car bodies at Kawasaki Heavy Industries. He built his expertise in welding mechanics and FEM-based distortion analysis during graduate studies at Osaka University, then applied it to on-site resistance spot welding process control and manufacturing engineering. Based in Kobe, he combines deep technical analysis with practical production oversight to reduce deformation and improve weld quality in large-scale vehicle structures. Notably, he bridges academic simulation techniques and hands-on施工管理, enabling smoother transitions from design validation to shop-floor robustness.
