An integrated system for intelligent seam tracking in robotic welding. II. Design and implementation

Abstract

For pt.I see ibid., p.1904-9 (1990). The design and implementation issues for ARTIST (adaptive real-time intelligent seam tracker), which is essentially a microcomputer-based single-pass system characterized by the absence of an additional teaching phase, are addressed. ARTIST uses a welding torch and a laser-ranging sensor mounted on the end-effector of a six-axis robot. Sources of error that could potentially contribute to inaccuracy in the seam tracking process are discussed. Suggestions are also made for enhancing the performance and applicability of ARTIST for welding automation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
