Leak testing and leak detection
According to Atlas Copco, a defined vacuum makes even the smallest leaks detectable ā in low to high vacuum. For leak test, leak detection and tightness testing systems, Atlas Copco names DRB, GLS and GVD.
Electron beam and vacuum welding
In vacuum welding, little O2 and N2 remain in the chamber so that the weld does not oxidise; Atlas Copco names low to high vacuum for this, without assigning a series.
