QCW Laser Welding Machine (Quasi-Continuous Wave)
QCW laser welding machine (Quasi-Continuous Wave) is a high-performance laser welding system that combines the advantages of continuous wave (CW) and pulsed laser technologies. It delivers high peak power in pulse mode while maintaining stable average power, making it ideal for applications requiring deep penetration, high precision, and minimal heat input.
QCW laser welding machines are especially suitable for welding high-reflective and high-conductivity materials such as copper and aluminum, which are difficult to process with traditional welding methods.
Key Features
- High peak power output with excellent penetration capability
- Stable and controllable heat input
- Small heat-affected zone and minimal deformation
- Excellent performance on highly reflective metals
- Supports both pulse mode and continuous mode
- High energy utilization efficiency
