Adaptive control hybrid welding system and methods of controlling

摘要

An adaptive control hybrid welding system including hybrid welding apparatus, control system connected to hybrid welding apparatus, and seam tracker connected to control system is provided. Hybrid welding apparatus includes a laser and an electric arc welder. Laser and electric arc welder each have adjustable welding parameters. Control system modifies welding parameters of laser and electric arc welder, and spacing between laser beam and arc of welder. Seam tracker is operable to measure seam property of adjacent workpieces prior to welding. Seam tracker is operable to send signals to control system in response to the measured seam property. Control system modifies welding parameters based on signal from seam tracker and adaptive control hybrid welding apparatus joins adjacent workpieces having variable gap sizes of up to 2.5 mm with full penetration welds. Also provided is a method of controlling the adaptive control hybrid welding system.
