Technology

FSW imag

Friction Stirring Welding

It is a solid-phase bonding method that utilizes frictional heat with the material while rotating the tool at high speed.

It is a method of bonding without melting the mother body, heating and softening as an individual, and further giving plastic deformation

Airtight Welding

We perform high-precision airtight welding for skilled engineers and correction of flatness using our own press machine.

Stainless steel water-cooled jackets and chambers are used in high vacuum levels, requiring high-precision airtight welding with Tig welding
