Processes

Quality inspection

Manufacturing process :

The traceability and  controls of our brazed ceramic-to-metal assemblies are applied  throughout the manufacturing process at SCT :

  • Dye penetration control (level 2 Cofrend accreditation)
  • Control of parts aspect with magnifying lens, manually or per automated method
  • Mechanical and optical dimension controls, manually or per automated method
  • X ray metallization thickness monitoring (MoMn, Ni, Ti,…) and protective layers (Au, Ag, Cu, ….)
  • Controls of electrical performances of brazed assemblies (insulation resistance, breakdown,…)
  • Control of temperature resistance of brazed assembly by thermal & VRT cycling (automatic climate chamber)
  • Control of pressure resistance of brazed assemblies (> 1200 bar)
  • Helium hermeticity control of brazed assembly (level 2 Cofrend accreditation)
  • Electrical controls of brazed assemblies in flight condition (change of altitude level)
  • X ray non-destructive testing of brazed assemblies welded and brazed joints
