FiberWELD® DH

FiberWELD® DH is a robust head with direct-cooled reflective optics that minimize focus shift. It’s engineered for high duty cycle production applications with medium to high power, fiber-delivered lasers. The head’s advanced optical design permits wire to be fed directly into the beam path – right into the center of the melt pool. This allows the laser or cladding process to have total directional independence. Also, FiberWELD® DH’s easily accessible, protective cover glasses extend the life of internal optics.
