Success factor 5: “Stress-free panels” for successful weldingCustomers continue to see more precise quality requirements for their raw sheet metal parts. These also include tighter tolerances. Under some circumstances, an un-leveled part may fail to fulfill the customer’s tolerance specifications. If un-leveled parts are welded together to form assemblies, the product may exceed the tolerances and require extensive reworking. Bent panels can also cause time-consuming problems with the welding process itself. These begin with the welding preparation when fitting the panels into the welding fixture proves to be time-consuming. During welding, the bent panels can also cause problems, especially with robotic welding: the deformed workpieces may not fit together precisely. Consequently, welding robots require an accurate welding gap to deliver reliable results. The use of levelers drastically reduces the welding preparation times and enormously enhances the reliability of the overall welding process.
