QCW quasi continuous
QCW Quasi Continuous Laser Welding Machine | High-Precision Metal Welding Solution
Available models: CZ-Q80 (80W), CZ-Q150 (150W), CZ-Q300 (300W)
Peak power reaches 1200W to 2500W for high-energy pulse welding
Combines advantages of both continuous and pulse modes
Ideal for precision welding of battery tabs, medical devices, and fine metal parts
Equipment Introduction:
The QCW (Quasi-Continuous Wave) laser welding machine combines both spot and continuous welding modes. With 30% photoelectric conversion efficiency and a maintenance-free design, it offers much higher performance and lower cost than traditional lamp-pumped YAG lasers.
It is ideal for welding thin-wall materials and precision parts. The system supports multiple welding types—spot, butt, lap, and seal welding—either in single-point or continuous modes. It delivers high peak power, stable output, and excellent beam quality, making it especially suitable for applications requiring long pulse durations and precise control.
Thanks to its compatibility, most existing YAG systems can be upgraded to QCW systems with minimal modification.
Equipment Features:
- Stable beam quality across full power range

1. Warranty Period:
Laser Machine: 18 months
Within 12 months, free replacement of parts, including the laser device.
For failures caused by non-human reasons, our company will send new accessories to customers for free, including the laser source.
Customers will need to send back faulty parts (laser source) first.
For other parts, there is no need to return them.
From 12 to 18 months, the customer will bear the laser cost and postage.
Both parties will share the postage cost for the return of the laser device.
The customer will send the faulty laser to our bonded warehouses in Jinan or Shenzhen, China. The purpose of this is to avoid complex customs procedures.
After 18 months, the laser source will cost, and the customer will need to buy the parts and cover the postage costs.
2. Laser Charging Instructions:
| Time | Laser | Remark |
| Within 12 months | Free replacement | Both parties pay the postal fee (If received within one month, customer bears no cost) |
| 12–18 months (During the warranty period) | Laser source cost × 0.2 | Both pay postage Send to bonded warehouse in China (Jinan/Shenzhen) |
| After 18 months (Out of warranty) | Laser source cost × 1.2 | Buy directly, customer pays postage |
1. What is a QCW laser welding machine and how does it work?
QCW (Quasi-Continuous Wave) laser welding combines the features of both pulsed and continuous lasers. It delivers high peak power for precision welding and supports longer pulse durations for better stability.
2. What are the advantages of QCW laser welding compared to pulsed or continuous welding?
It offers higher energy per pulse than pulsed lasers and more control than continuous lasers. It’s ideal for applications that require deep welds with minimal heat distortion.
3. What materials are suitable for QCW laser welding?
Suitable for stainless steel, carbon steel, aluminum, copper, nickel, and other reflective or thin metals used in electronics, batteries, and medical devices.
4. Can QCW laser welding be automated or integrated with fixtures?
Yes. QCW machines support multi-axis motion control and can be integrated with automated systems, precision fixtures, and wire feeders.
5. What are the typical industries using QCW laser welding?
Common in battery manufacturing, electronic parts, medical devices, sensors, and fine metal components that require precision and strength.
