Laser Beam Welding (LBW)

LASER BEAM WELDING SERVICES

Advance Welding (formerly KTI, Inc.) performs high-precision Laser Beam welding for a wide variety of applications. Utilizing CNC motion control, we produce the highest quality welds for medical devices, automotive applications, sensor assemblies, and more. 

Our equipment is comprised of an IPG 2kW Continuous Wave Fiber Laser and a LaserStar 7000 Series Pulsed Laser. Motion is controlled via 4 axis CNC along with a high-performance galvanometer scanner.

Our engineering staff is eager to assist you in joint design and material selection to fit your needs. We offer value-added services, prototype to production lot sizes, multi-shift operation, and In-house tooling capabilities.
