The process of welding aluminum presents a considerable challenge to the application of robotic welding. Heat distortion and fixturing errors often require alteration in welding parameters and the welding torch position and orientation in realtime. A nonadaptive robotic welding system, or a system with only limited sensory ability, is consequently unable to perform well in many aluminum welding tasks. A strong need exists in the aluminum fabrication industry for sophisticated flexible automated welding systems, which implement expert systems for weld process control and multipass weld planning, and apply advanced sensory technology for realtime seam-tracking and joint geometry' measurement.
