Gas tungsten arc welding (GTAW) uses argon gas as a protective in the process. Argon cylinders weigh 100 kg, making it difficult to mobilize large quantities when work is at certain height. Therefore necessary create storage area that able accommodate and withstand load of their contents can be mobilized In order get suitable area, design has been carried out, which includes calculating strengt...

In this investigation, an attempt is made to study the tensile and microstructural impact of different gas tungsten arc (GTA) welding processes pulsed current, constant magnetic oscillation welded AZ31B magnesium metal joints. These techniques were chosen because they have potential produce welds with high strength excellent integrity. Five joints produced using each approach, one employing a u...

Sensing plays a key role in automating and controlling welding processes. Although arc light sensing has advantages over through-the-arc sensing for arc length control and seam tracking, the current technology relies on experimental data and lacks theoretical foundation. To improve measurement accuracy, this work addresses the theoretical foundation for arc light sensing. A theoretical model ha...

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...
