The QCW (Quasi-Continuous Wave) fiber laser welding machine is developed for industrial processes that require a combination of extended pulse duration and high peak power. Instead of delivering energy continuously, the laser releases controlled pulses to concentrate energy within the welding area. This operating principle makes QCW technology suitable for applications such as spot welding and seam welding, especially when the process requires a defined amount of energy within a controlled time window. It can be used for a variety of metal joining tasks where localized heating and repeatable pulse output are important.
The system provides a fiber laser-based alternative for certain welding applications traditionally performed with YAG laser equipment. QCW technology can deliver the required pulse characteristics for processes that depend on concentrated laser energy, while the fiber-based architecture provides a different equipment platform from conventional YAG systems. This makes the machine suitable for manufacturers considering the replacement or modernization of selected YAG welding equipment while retaining similar pulsed-laser processing principles.

The QCW fiber laser architecture is designed to reduce the routine service work associated with traditional lamp-pumped YAG systems. By eliminating regular lamp replacement as part of normal operation, the system can reduce maintenance tasks and help limit production interruptions related to consumable laser components. For manufacturers operating equipment over extended production periods, fewer routine service requirements can contribute to lower maintenance expenditure and more convenient equipment management.
Hanwei Laser has developed the key optical and control technologies used for the QCW system, covering high-speed laser beam distribution, energy distribution, and timing control. These hardware and software systems coordinate how laser energy is divided and delivered during processing. The integrated architecture provides a controlled method for managing output energy and timing, while also giving the equipment a foundation for applications requiring multiple processing paths or specialized welding sequences.
