TIG & MIG Welding

TIG and MIG welding where weld quality decides system performance, with leak-tight UHV weldments as our core strength.

Overview

Welds that hold a vacuum.

Our welders hold AWS certifications in TIG (GTAW) and MIG (GMAW). The specialty is ultra high vacuum: controlled weld procedures for chambers, sealed assemblies and leak-tight systems used in semiconductor, space and research hardware.

Every UHV weldment is verified with helium leak detection before it leaves, and welded assemblies can go straight to post-weld machining and inspection on the same floor.

Typical work
  • Vacuum chamber fabrication and repair
  • Structural frames and enclosures
  • Post-weld machined assemblies
  • Aluminum, 316L stainless and carbon steel
