Our welding and joining expertise is broad, ranging from fusion welding processes such as arc, laser, electron beam and resistance welding, brazing and soldering, to non-fusion techniques such as friction and ultrasonic welding, and diffusion bonding, as well as adhesive bonding. We have advanced the welding and joining of a variety of materials including metals, plastics, composites and ceramics. We have even developed processes to weld wood.
