QCW (Quasi-Continuous Wave) laser welding is a technique that utilizes a high-peak-power laser to weld materials using short pulses. This method offers several advantages, including a minimized
heat-affected zone and greater flexibility compared to continuous wave (CW) laser welding. A QCW laser can operate on high-peak-power pulse modes, providing peak power up to ten times the average power.
Advantages of QCW Laser Welding:
Minimized Heat-Affected Zone (HAZ):
QCW lasers deliver energy in pulses, allowing the material to cool between pulses. This approach reduces thermal input and minimizes the heat-affected zone. Suitable for thin materials.
The reduced thermal input makes QCW welding ideal for thin materials, where excessive heat can cause distortion or damage. It is suitable for aluminum (from 0.020” to 0.063”) and stainless steel (up to 0.040”). Additionally, it can be used with painted coils.
Skills: Achieving optimal results with QCW laser welding can be mastered quickly.
