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 inspection standards 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 product performance.
