Hermetic Sealing Systems

AMADA WELD TECH provides a range of resistance welding based systems that include projection and rotary welders, hermetic seam-sealing systems, and lid-placement and tacking systems. Packed with advanced features, these systems reliably perform welding, brazing and soldering processes on a variety of hermetic sealing applications.

Our Hermetic Sealing Systems can be operated as stand-alone units or fully integrated into atmospheric enclosures to provide an integrated seam-sealing glove box system which ensures high-yield results for hermetic sealing.

Learn more about the different Hermetic Sealing processes and solutions we provide for joining metals, metal alloys, plated materials and solder-preforms.


Lid Placement, Tack and Seam Sealing System - AF8500

The Auto flow system is flexible enough to meet the ever-increasing demands of lid placement and seam-sealing applications as seen in the optoelectronic packaging industry. It can be configured either as a stand-alone unit or as part of a fully-integrated, automated manufacturing line. The computer-controlled precision tacking and seam-sealing mechanism is combined with a high-frequency inverter welding power supply and an optional high-resolution vision system to provide a robust and repeatable process.  Auto flow can also be incorporated into an atmospheric enclosure to provide an integrated seam sealing glove box system, ensuring high-yield hermetic sealing results.


  • Current control mode for sealing
  • Programmable electrode force
  • Most complete line of power supplies in the industry
  • Vision system
  • Electrode roll-back feature
  • Automated magazine loader option
Parallel Seam Sealing System - SM8500

Packed with advanced features, the Windows®-based SM8500, reliably performs hermetic resistance welding, brazing, and soldering processes on a variety of metals, alloys, plated materials, and solder pre-forms. SM8500 can be operated as either a stand-alone unit or fully integrated into a glovebox enclosure for a complete closed-loop hermetic sealing process for applications that include optoelectronic packaging, semiconductor packaging, transistor outline package welding.


  • Current control mode for both the hermetic welding and sealing process
  • Programmable electrode force
  • Most complete line of power supplies in the industry
  • Extended electrode life with electrode Auto-Trak software
  • Position-based weld pulses
  • Electrode roll-bak feature
  • Process inhibits
