Panel Welding System
US Patent:
4392604, Jul 12, 1983
Filed:
Aug 27, 1980
Appl. No.:
6/181863
Inventors:
Stanley L. Sears - Seattle WA
Assignee:
The Boeing Company - Seattle WA
International Classification:
B23K 3702
B23K 3704
B23K 3704
US Classification:
228212
Abstract:
An integrated welding torch and work positioning roller head assembly is mounted for controlled movement on a cross travelling gantry carriage overlying a vacuum hold-down bed that supports a workpiece panel. The torch and roller head assembly has two related configurations, one for forming a butt weld along a seam joining edgewise abutting sections of flat stock to form a relatively larger unitary panel, and another head configuration for subsequently positioning and fillet welding stiffener webs to one face of the panel. Each of the head assembly configurations is provided with a cofunctioning arrangement of a welding torch (or torches) and seam tracker (or seam trackers) for positioning the torch (or torches) relative to the head assembly as the assembly is automatically guided by the gantry carriage along the intended seam, and a plurality of workpiece positioning and holding rollers which cofunction with the vacuum hold-down bed to form distortion-free panels, having consistently uniform welds along the seams, without the need of preliminary tack welding and without requiring special purpose jigs and tooling for each different panel and stiffener shape.
