Intelligent Gas Tungsten Arc Welding Control
Project Title:Intelligent Gas Tungsten Arc Welding Control
Nashville, TN 37207
Principal Investigator:Barnett, Robert Joel
A research program is proposed to establish the feasibility of combining the comprehensive
rule-based of an expert gas tungsten arc welding system with sensory feedback, modeling,
and multivariable control algorithms to intially set and adaptively control the weld
process in a changing environment. It will be the objective of the proposed research
to demonstrate the feasibility of accomplishing this for full penetration welds,
partial penetration welds, tack welds, and thin-section-to-thick-section welds.
The Phase I feasibility research program proposed will pave the way toward an extensive
Phase II research program to develop a more fundamental understanding of the gas
tungsten arc welding process, and the creation of an intelligent Welding Process
Control System capable of adaptively adjusting to process stability, gas shielding,
consumable quality, workpiece contaminates, joint variations, etc.
