FOCUS ON WELDING
The laser scanner scans the work surface of the component and saves the result . The system converts the stored data of the scanner into a 3D model .
directly on a ground track , and is moved horizontally by a carriage . Since the welding program with all welding parameters ( such as speed , wire feed and gas ) has already been specified , the robot can start welding immediately . Overhead positioning of the robot ensures optimum accessibility , as well as better welding positions . Additional movement devices and extensions are also easy to implement . The MAG pulse arc enables it to achieve optimum weld seam quality at high weld speed ,” added CLOOS .
An arc sensor is used for all welds . For welding the riser seams of the workpieces , a separate pendulum figure is defined in which the measuring points of the sensor are programmed . A tactile sensor with welding wire is used as a “ stylus ”. Since clean nozzles
CLOOS RoboPlan software . are a prerequisite for exact adherence to welding parameters and good quality of the weld seam , a fully automatic welding torch cleaning is also part of the robot system .
Flexible and versatile
In addition to the large workpieces , various other sheet metal parts ( including ribs and connector plates ) are manufactured by construction specialist , Schwevers . It can use the robot system flexibly in either one- or twostation operation .
“ This not only allows us to weld steel beams automatically , but also to process smaller parts . That is real added value for us . We are happy to have such a competent partner at our side , who solves tasks openly and appreciatively ,” announced Heinz Schwevers .
In two-station operation , the system can be equipped by the operator on one side while welding is done on the other side . This leads to time savings in the production process and shorter project times for the hall construction specialist . This flexibility also requires safety adjustments . Technical measures , such as fixed guards ( e . g . protective fences ) or non-contact ones such as light barriers , can be adapted according to requirements to
The robot system also includes fully automatic welding torch cleaning .
The operator can check the result and make corrections , if needed .
protect the operators , for example , from robot movements .
Markus Rompf , a longstanding application engineer from CLOOS in charge of the installation , explained : “ Everything slotted in well together . During this project with Schwevers , we continuously improved the software and overall product recognition so that a wider range of components could be processed by the QIROX RoboScan . The partnership between CLOOS and Schwevers was simply great . I think we all benefited from the project !” n
