The welding robot of the new, enlarged version of TruLaser Weld 5000 processes parts up to four meters in length. There is enough space in the booth of the XXL system for large assemblies, such as big casings or water tanks. Users benefit from the advantages of the laser even when working with components on this scale. Whether robust or attractive welds, the laser does both and saves on rework.
Positioners for various requirements
The robot of the TruLaser Weld 5000 travels along a linear axis, which means it can cover a large work area. As a complementary feature, the system also possesses a four-meter-long turnover positioner with a carrying capacity of up to 1,000 kilograms. It owes its name to a turning axis, which the positioner uses to align assemblies for the welding robot. Parts with dimensions of up to 4,000 millimeters in length, 1,500 millimeters in width and 1,000 millimeters in height can be welded with the new system; depending on the position of the seam, it can handle even larger components. The booth is up to 9.4 meters long, accessed by a door four meters wide. Its interior accommodates additional component positioners, such as a table that can turn and tilt. Thanks to this feature, users can weld complex parts without having to interrupt work to reclamp them. Another positioner allows users to load the system from the outside while the welding robot works in the cell.
New developments in optics and programming
In addition to the larger format, there are also new developments in the optics of the TruLaser Weld 5000: a built-in sensor system during operation monitors whether, and to what extent, dirt has accumulated on the protective glass. LEDs on the optics and messages on the system’s user interface display the degree of contamination. In this way, the sensor system supplants visual inspections and saves time. Also new, via the welding program, users can set the amount of shielding gas and the strength of the compressed-air crossjet at the optics. There is thus no need for manual intervention.
One system, three welding methods
Like the standard version, the enlarged version of TruLaser Weld 5000 facilitates three different laser welding methods. The component decides which is the most cost-effective solution. Heat conduction welding joins together thin-walled parts and produces seams of very high surface quality. In many cases, this eliminates the need for any subsequent grinding and polishing of the seam. Deep penetration welding produces deep, narrow, high-strength weld seams. It can be used with both thin and thick-walled metal sheets – and gets the job done fast. Heat conduction and deep penetration methods offer the best quality when it comes to laser welding. To achieve this, components generally have to possess very low tolerances. However, the FusionLine technique can be used to join components that have somewhat larger gaps. It smooths out any unevenness during the welding process and closes gaps up to one millimeter wide. This makes it possible to use the laser on many parts that users may have originally designed for conventional welding methods. As a result, FusionLine provides an easy introduction to the world of laser welding and enables users to increase the capacity utilization of their machines. Without retooling the TruLaser Weld 5000, users can easily switch between FusionLine and other laser welding methods, even during the processing of a component.
