Automatic inspection of welding spots during production
In welding processes, the optical 3D measurement device InfiniteFocus® is used to automatically measure and classify welding spots and solerding joints during production. The inline surface inspection is performed in seconds and saves costly rework. A 100% inspection and automatic classification with go/no go status is achieved through robust surface measurement. This can be achieved across the geometry of the whole spot including steep flanks, complex reflection properties and scale caused by burning.
100% inspection and automatic classification with go/no go status is achieved through robust surface measurement.
To define go/no go parameters such as irregularities due to scaling, topography is measured including the fully registered 3D color information of the welding spots’ topography. This unique combination of robust topographical data and true color information provides the go/no go data for weld classification plus advanced metrology information. This detailed information provides advanced quality assurance as scaled patches are easily identified, quantified and measured. InfiniteFocus® is also used for the 3D measurement of pins and pads.
