Abstract
Feed process control is accomplished using an optical profiler to determine the height, width, and cross sectional area of a bead produced by a bead producing tool. Feedback control of the height, width, and/or area is obtained by modifying various parameters of the bead producing tool. If the bead producing tool is a welding torch, the parameters may include the weld torch voltage, weld torch current, wire feed rate, and the speed of travel of the torch across the workpiece or workpieces. If the bead producing tool is a sealant or glue gun, the parameters may include the pressure of the sealant or the glue supplied to the sealant or the glue gun, the size of an adjustable nozzle orifice of the sealant or the glue gun, and the speed of travel of the sealant or the glue gun along the surface of the workpiece.
