Weld depth control in fiber laser welding of thin metal sheets
ICALEO 2008: 27th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2008Laser beam welding of electrical connections or sealing of casings are typical applications in the field of precision engineering. Controlling the shape of the welded connections is an important issue in this context. A common requirement is for example to achieve a specific welding depth in order not to damage functional layers or contaminate the ...
