Seam tracking of intelligent arc welding robot

Abstract

Abstract: Intelligent welding robots obtain a good quality of the welding results. Research on automatic and intelligent control of Arc welding is an important means for ensuring weld quality, raising productivity, and improving labor conditions. Despite its widespread use in the various manufacturing industries, the full automation of the robotic welding has not yet been achieved partly because mathematical models for the process parameters for a given welding tasks are not fully understood and quantified. The first problem that should be solved for the automation of welding processes is weld-seam tracking. In this research, an attempt has been made to recognize path of weld groove by vision.
