Process monitoring and quality assurance
To ensure that laser welding systems guarantee consistent quality even in the most complex welding processes
In the production of vehicle parts such as tailgates, car doors, hairpins or battery boxes, weld seams are produced by laser at extremely high speeds. Defects in the weld seam such as incompletely welded seams, weld seams that are not 100 % positioned, pores in the weld seam, seams that are not continuously welded, undercuts, etc. are at the expense of stability, tightness and visual appearance. Quick intervention in the process prevents further costs for rework or even rejects. System solutions for process monitoring and quality assurance ensure that weld defects are detected directly and can be identified and quickly reworked before the component is further processed.
What are the tasks of quality assurance and process monitoring?
The quality assurance of joining processes ensures that the components to be joined form an inseparable connection in accordance with the customer's specifications and then fully meet the quality requirements. This includes stability and load-bearing capacity as well as tightness and visual appearance.
Process monitoring tracks the laser joining process and controls the process stability. It is not itself a quality measurement procedure, but rather a tool that helps in the early detection of error causes. The detection of welding defects during the process is a great advantage, especially in automotive manufacturing. Subsequent repairs of hairpins or electric motors, for example, are very difficult or impossible from a technical point of view. If a defect is detected during the process, it is possible to intervene in production and prevent the continuation of the defect on other components. This is referred to as predictive process monitoring.
