It has been 25 years since we started TIG welding of stainless steel. We have inherited Tsubame's advanced technology. During that time, we have developed various unique technologies. In particular, we have developed our own technology to prevent oxidation due to the heat generated during TIG welding. Patented in 2013.
Realizes durable and beautiful welding that is not seen anywhere else.



Shinken Industry boasts welding and polishing technology.
Our two technologies are indispensable for manufacturing vacuum chambers that can withstand harsh vacuum environments.
