The improvement of the welding methods, the widespread use of laser welding and subsequent treatments such as annealing and coating have made the automatic detection and positioning of weld seams in tubes for subsequent processing steps such as tube bending and hydroforming a difficult task. The use of specifically designed sensors in conjunction with digital signal analysis with microprocessors or PC based systems has therefore gained widespread acceptance. ROLAND ELECTRONIC GmbH meets many needs of customers regarding to remote maintenance and presents a comfortable solution for the Weld Seam Detection System SND40, the Remote Service Box RSB.
