Purpose – Welding sensor technology is the key technology in welding process, but a single sensor cannot acquire … adequate information to describe welding status. This paper addresses arc sensor and sound sensor to acquire the voltage and … sound information of pulsed gas tungsten arc welding (GTAW) simultaneously, and uses multi‐sensor information fusion …

Purpose – The paper aims to report on a new welding technology, TIP TIG. Design/methodology/approach – The principle of … technology provides the quality of TIG welding at the speeds of MIG welding, providing significant cost savings to the user …. Practical implications – TIP TIG provides a good opportunity for all users of robotic MIG welding to improve the quality of …

Purpose – The control of weld penetration in gas tungsten‐arc welding (GTAW) is required for fully automated systems to … overcome variations in the welding process. The surface depression of weld pool, or weld pool height, has a close relationship … reconstruct a 3D shape of welding pool from a 2D image, which was obtained from a real welding pool. Then the pool height can be …
