AN EXPERT SYSTEM FOR ROBOTIC ARC WELDING

Abstract

A new class of programs called expert systems are capable of drawing conclusions in the manner of a human expert and disseminating knowledge for general use. In the field of welding, this type of program may close the gap between a qualified robot operator who is inexperienced in welding and the skilled welder. With such a program, a robot operator is not only able to fulfil most of his welding tasks - he will also be able to react when welding problems like defects occur. He can use the expert system as if he were consulting with an expert. The purpose of this article is to describe the applicability and usefulness of expert systems in the context of welding.
