To minimize deformation from welding, we use optimal ZIG.
Products requiring high precision are processed a
secondary machining (No.45867850) to correct for any
deviation from the target measurement. In cases of
highvacuum environment, we use the back bead welding
process to manufacture vacuum pipes.
To prevent oxidation and minimize outgassing, we weld only
after nitrogen charging.
We use different welding processes depending on the
environment and characteristic called for.
Smallcaliber ports connected to vacuum pipes are
relatively weak to physical force. We resolve this by
testing tensile strength.
We adhere to the manufacture, management and
inspectionstandards for vacuum welding.
We check the interior welding status, which is the most
important part of vacuum pipe quality control.
We focus not only on the exterior condition of our
products but also the interior, which directly affect
