I. Abstract: The prediction of the optimal weld bead width is an important aspect in shielded metal arc welding (SMAW) process as it is related to the strength of the weld. This paper focuses on investigation of the development of the simple and accurate model for prediction of weld bead width of butt joint of SMAW process. Artificial neural networks technique was used to train a program in C++...

Welding is a very complex process in which the final weld quality can be affected by many process parameters. In order to inspect the weld quality and detect the presence of various weld defects, different methods and systems are studied and developed. In this paper, a laser-based vision system is developed for non-destructive weld quality inspection. The vision sensor is designed based on the ...

Electrospark deposition (ESD) was studied to investigate the possibility of forming non-equilibrium microstructures in Al alloy systems. The results have demonstrated that the level of supersaturation is system-dependent. The Al-10 wt% Mg system exhibited a complete supersaturation, while the Al-Si system had a supersaturation level reaching about 1wt%. The ESD process was also used to demonstr...
