...Yanling Xu; Huanwei Yu; Jiyong Zhong; Tao Lin; Shanben Chen Purpose The purpose of this paper is to analyze the technology of capturing and processing weld images in real‐time, which is very important to the seam tracking and the weld quality control during the robotic gas tungsten arc welding...

... gas tungsten arc welding (GTAW) simultaneously, and uses multi‐sensor information fusion technology to fuse the information acquired by the two sensors. The purpose of this paper is to explore the feasibility and effectiveness of multi‐sensor information fusion in pulsed GTAW. Design/methodology...

.... Practical implications The control system is applicable to automatic gas tungsten arc welding (GTAW). Originality/value The MISO MFC has been set up for automatic GTAW to overcome the nonlinear and uncertainty of GTAW process, in which two welding parameters can be adjusted simultaneously. In addition...

...Youlun Xiong; J.F. Wang; W.Y. Wang; S.B. Chen 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...

... Publishing Limited 2007 Gas tungsten‐arc welding Welding Robotics The first application of TIP TIG in the UK has demonstrated the success of this technology. The growing number of installations around the world also shows that there are many users who are convinced by the benefits of TIP TIG...
