The new StarWeld Tool Open from Laser Resources enhances the process of mobile laser welding. By eliminating the time consuming process of dismounting large tools or moulds, site repairs can be accomplished and laser welding can be made a flexible and location-independent process.
A weight-compensated hinged bracket arm positions the welding head over the workpiece with speed and precision. A horizontal range of 1.70 m and a height of 1.80 m helps to reach the target even on large moulds or tools. Alignment of the positioning axes parallel to the welding seam allows an intuitive control of the traveling paths. The system is controlled via a joystick during the welding process. Normally, this is enough to control one axis only.
Everything on board – everything in view
An integrated water/air cooling unit, positioning arm, 150 W of laser power and XYZ-axes system are integrated into a mobile, compact unit. A microscope or a camera with LCD screen is provided for surveillance of the halogenlamp- or LED-illuminated processing area. A trinocular configuration is also offered if desired. Programming close to the workpiece is possible with the removable system control box.
High beam quality – precise weld seams
The Nd:YAG laser with the Sweet Spot resonator provides a combination of optimal first pulse behaviour and high beam quality. The laser was particularly optimised to facilitate deployment with optical fibers. Motorised focus adjustment of 0.4 to 1.6 mm and pulse shaping expand the options in setting weld seams. This contributes to a reduction in post-processing and repairs are made cost effective.
