METHOD AND EQUIPMENT FOR WELDING SOLID SHEET METAL STRUCTURE

摘要

PURPOSE:To perform laser beam welding on sheet metals of solid sheet metal structures at a high speed by using a small-sized and lightweight welding head. CONSTITUTION:The laser beam welding head 4 is fitted on the hand 3 of a robot, a laser beam is introduced into the welding head 4 from a laser beam generator 1 of iodine laser by fiber beam transmission and while joining flanges 13 of two sheet metals 11 are squeezed by at least a couple of rollers 18 and 19 of a roller unit 5 provided fixedly on the welding head 4, the welding head 4 and the roller unit 5 are moved synchronously to weld and join both joining flanges 13. A cutting head is arranged on the welding head 4 and useless joining flange 13 parts are cut and removed after welding.
