Hermetic sealing systems

Laser Hermetic Sealing Equipment

Select a laser welding platform around the atmosphere, package geometry and verification requirements of your metal enclosure. JMLASER systems support controlled-atmosphere, vacuum and protected-enclosure welding workflows.

Start with three decisions

  1. 01
    Welding environmentAir, inert gas, vacuum or shielded enclosure
  2. 02
    Package and materialGeometry, alloy compatibility and contamination control
  3. 03
    Quality verificationWeld inspection and hermetic leak testing

Equipment pathways

Choose by welding environment

Each platform addresses a different level of atmosphere control. Review the equipment family that most closely matches your process.

Engineering guides

Define the seal, then verify it

Start with the design differences between hermetic and general laser welding. For material-specific development, review titanium shielding, fit-up and inspection, then define complementary gross- and fine-leak test coverage.
