The 750W QCW Fiber Laser Welding Machine is a compact precision laser welder designed for thin sheet metal welding and delicate metal fabrication. Featuring quasi-continuous wave laser technology, integrated water cooling and precise pulse control, it delivers concentrated laser energy with low heat input, helping minimize welding distortion and achieve clean, consistent weld seams on compatible metals.

750W QCW Fiber Laser Welding Machine
The DAPENG CNC 750W QCW Fiber Laser Welding Machine is a compact, high-precision laser welding solution designed for thin metal sheets, precision components and delicate metal fabrication applications.
Using Quasi-Continuous Wave (QCW) fiber laser technology, this industrial laser welder delivers controlled laser pulses with a maximum peak power of 750W, enabling localized welding with concentrated energy and reduced heat input.
The compact machine structure integrates an efficient water-cooling system, providing reliable thermal management without requiring a separate external industrial chiller.
Featuring advanced optical beam shaping and precise laser power control, the QCW laser welding system helps produce uniform weld seams while minimizing thermal distortion, spatter and visible welding marks under suitable processing conditions.
The machine is suitable for precision welding of stainless steel, galvanized steel, aluminum alloys and other compatible metal materials. It is particularly useful for thin sheet metal fabrication, decorative metal products, lighting fixtures and precision industrial components.
With a compact footprint, flexible welding operation and adjustable laser parameters, this 750W QCW laser welder offers an efficient solution for manufacturers requiring controlled heat input and consistent welding quality.
DAPENG CNC provides customized laser welding solutions and technical support for overseas distributors, equipment manufacturers and industrial fabrication businesses.
