Learn about welding processesEVO 0750 AQW – Dual-Wavelength Laser Module
The EVO 0750 AQW is a laser module with a customized optical setup for contour and quasi-simultaneous welding of plastics using two wavelengths. The patented Advanced Quasi-Simultaneous Welding (AQW) process combines two lasers within a single processing head, enabling simultaneous or alternating irradiation tailored to the material.
This results in optimized energy input, reduced cycle times, and improved weld strength. By heating both joining partners, the process expands the range of possible material combinations and ensures high-quality welding results.
The module can be flexibly configured for different laser plastic welding applications and is also suitable for use in test environments, enabling both transparent-to-transparent and transparent-to-absorbing processes within one system.
Additional monitoring modules, such as integrated displacement measurement in the clamping unit and other online control systems, ensure consistent weld quality and stable, reproducible processes.
Frequently Asked Questions
Dual-wavelength laser welding allows simultaneous or alternating heating of both joining partners. This results in faster melting, improved weld strength, and more stable processes compared to single-wavelength systems.
The EVO 0750 AQW is ideal for challenging applications where standard laser welding reaches its limits, such as difficult material combinations, transparent-to-transparent welding, or components requiring higher mechanical strength and shorter cycle times.
The system supports both transparent-to-absorbing and transparent-to-transparent material combinations. The use of two wavelengths expands the range of weldable plastics and enables new applications that are not possible with conventional laser welding.
By distributing energy more evenly between both joining partners, AQW reduces thermal stress and improves process stability. Combined with integrated monitoring systems, this ensures consistent, reproducible weld quality even in demanding production environments.
