This paper presents an evaluation of an infrared sensor for monitoring the welding pool temperature in a Gas Tungsten Arc Welding (GTAW) process. The purpose of the study is to develop a real time system control. It is known that the arc welding pool temperature is related to the weld penetration depth; therefore, by monitoring the temperature, the arc pool temperature and penetration depth are...

This study addresses intelligent techniques for fulfilling quality control of bead-on-plate welding. A new visual double-sided sensing system capable of imaging the weld pool topside and backside simultaneously in a frame was provided to determine the weld pool geometry parameters. The imaging principle was analyzed with spectrum distribution, in which the weld pool was illuminated by arc light...

Tungsten Inert Gas (TIG) welding is otherwise known as the Arc soldering (GTAW) process which when significant levels of weld quality or high precision are required, to represent an advanced arc process. However impact factors on this form important for its produced in single-pass welding. In investigation, autogenous was performed a carbon mild steel plate with four parametric variables. High ...

Argon arc welding is a frequently used process, to assist various manufacturing processes. The paper highlights the postweld experimental results of similar (EN 10025 Steel-Grade S295) and dissimilar (D36 shipbuilding steel) materials, which possess wide range applications in industries. In this work, studies are carried out for optimality gas tungsten (GTAW) parameters on butt joint with singl...
