Designed by SISMA in Italy, the SWA Series delivers consistent weld quality on a variety of metals using flash-lamp pumped Nd:YAG lasers. With fibre-coupled laser delivery, integrated cooling, and intuitive controls, it is suitable for both large and small mould work and detailed fabrication jobs.
Sisma Laser Welding SWA Series
The SWA Series combines robust mechanical movement, advanced software functions like overlap and circular weld paths, and stable laser beam delivery for reliable operations. Available in 150 W and 300 W variants, it supports long daily working sessions with minimal maintenance.
Features
Designed for long work sessions without losing precision or quality.
Manages complex operations like circumference welding, working on inclined surfaces, and filling with the Overlap function for regular seams.
The welding head can be positioned and rotated flexibly, adapting to maintenance needs on irregular-shaped molds, including inner parts.
Uses a flash lamp-pumped Nd:YAG laser that is transmitted through a fiber-coupled cable, ensuring an extremely stable and consistent laser beam without significant power loss.
Features a multitude of programmable path settings, including Overlap, Line, Radius, Oblique, and Fill paths, to help you get the job done quickly and accurately.
