Design of a Coaxial Welding Torch with Visual Sensor and Its Application

Abstract

Abstract:

Abstract： For the issues of structural redundancy, interference of the welding torch and images deviation from the center of weld pool caused by separation between the welding monitoring system and torch, a coaxial welding torch with visual function (coaxial integration with the visual function, CIV) was designed, whose camera is coaxial to the tungsten electrode, installed in the interior of the welding torch, which can provide real time monitoring of the welding processing. Innovation design of the tungsten electrode regulating system simplifies the regulation of tungsten electrode. The cooling and protection system were integrated, which has a dramatically effect on welding gun cooling and gas shielding. It not only optimizes the structure of the welding torch, but also improves the accessibility of the welding gun. The result shows that a very central pool image of tungsten and the exact positions of tungsten and welding stick can be obtained by the structure of the CIV torch. The structure of CIV torch is more advantageous in the applications of seam tracking, process monitoring.

Key words: visual sensor, coaxial, integration, welding torch, tungsten electrode
