Mobile Systems unique mobility Photo: Schweißpunkt GmbH, Mühlacker ALFlak With our flexible laser for deposit and contour welding – ALFlak – we offer you even more possibilities for mobile laser repair welding. Scope of motion and reach have been considerably extended, so that even welding spots in deep, complex moulds can be reached without problems, using the long laser arm. Welding seams of up to 500 mm length can be performed without a break. The ALFlak is available with a self-driving caterpillar track or as a manually transportable model. A unique comfort is provided by our patented, semi-automatic user-coordinate-control via WINLaserNC Software.
