The quality of Tungsten Inert Gas welding is dependent on human supervision, which can’t suitable for automation. This study designed a model assessing the tungsten inert gas with potential application in real-time. used K-Nearest Neighborhood (KNN) algorithm, paired images visible spectrum formed by high dynamic range camera. Firstly, projecting image weld defects training set into two-dimensi...

This paper provides a general introduction to welding fundamentals (section 2) followed by sections on a few selected welding processes that have had significant developments or improvements over the last few years. The processes that are discussed are friction welding (section 3), hot plate welding (section 4), ultrasonic welding (section 5), laser/IR welding (section 6), RF welding (section 7...

Understanding the joining process in real time during welding can help improve quality, reliability, and manufacturing efficiency. For this purpose, a laser ultrasonic method that detect situ quality without contact would be useful. However, behaviors of propagation as well melting with increasing temperature remain unclear. Therefore, study aimed to experimentally investigate in-process behavi...

Aluminum alloy has been widely used due to its excellent workability, and double-pulse metal inert gas welding (MIG) become a popular technique in aluminum welding. In this study, cross-complementary test was performed study the effect of characteristics on weld bead formation mechanical properties MIG The carried out an AA6061 using flat overlaying After welding, micro-metallographic structure...
