Materials Welded

Our lasers can weld a variety of materials from aluminum and Kovar to stainless steel, titanium and Inconel, to mention a few.  If you’re not sure whether a certain material can be welded, just let us know and we’ll work to help you find the best solution and/or try a sample to demonstrate the weldability.


We use top-of-the-line glovebox laser systems that are designed and assembled in-house.  Whether you need hermetic sealing in a nitrogen/helium or argon/helium atmosphere, our systems are set up for your part.  With multiple vacuum-bake ovens, we can have a variety of parts running through the process at the same time, allowing for quick turn-around to meet the most demanding schedule.
