Summary: Gas metal arc welding (GMAW) is an important industrial process, and there have been efforts to convert it into a stable process with minimal human interference. However, achieving automated control similar to a human expert is still challenging. This research introduces two intelligent systems for real-time control of weld bead geometry in the GMAW process.

Summary: This study systematically investigates the relationship between welding process variables and welding bead geometric features, as well as optimization of welding quality. By establishing models and using the desirability function approach, suitable welding parameters are recommended to meet the conflicting demands of multiple bead geometric features.

Summary: Submerged arc welding is a complex metallurgical process with temperatures exceeding 2000 degrees C. The variation of oxygen content in the metal during the welding process remains unclear. A thermodynamic approach based on Oxygen Layer Theory, Local Attained Equilibrium, and Scheil Solidification has been proposed to estimate the trend of oxygen content variation. The approach has shown to be effective in predicting the variation of oxygen content when using typical CaO-Al2O3 based fluxes and evaluating factors influencing oxygen content levels from a thermodynamic perspective.

Summary: This study evaluates the significance of considering the latent heat effect during phase change in a three-dimensional finite element numerical simulation of arc welding. The developed mathematical model incorporating latent heat effect provides accurate predictions compared to experimental values. It is crucial to account for the latent heat of fusion, solidification, and vaporization in numerical simulations involving phase change analysis.

Summary: A novel methodology has been developed to recycle steel slag as a flux for submerged arc welding, and optimize the welding parameters using various optimization techniques. The genetic algorithm technique showed the best results with minimum errors in penetration, bead width, and reinforcement. Additionally, it was observed that the flux manufactured from waste slag produced a desired bead profile similar to that of fresh flux, with optimum bead geometry achieved.

Summary: In this study, the effect of cold wire tandem submerged arc welding (CWTSAW) process parameters and bevel design on the weld geometry and properties of heavy gauge X70 pipe were investigated. The results showed that the cold wire feed speed significantly influenced the micro-hardness profiles, while bevel design was the main factor affecting the reinforcement size and coarse-grained heat-affected zone (CGHAZ) area. The microstructural analysis revealed lower amounts of martensite-austenite (MA) constituents in the CGHAZ of the CWTSAW samples, resulting in lower hardness.

Summary: The study introduces a new technique for controlling weld-induced distortion by preheating the welding filler wire, showing that as the preheat value increases, the welding current decreases, leading to more stable arc characteristics and effectively reducing the longitudinal bending distortion of the sheet.

Summary: In this study, statistical design techniques and artificial neural network were used to predict the weld bead shape parameters of shielded Gas Metal Arc Welded (GMAW) fillet joints. Comparisons were made using an empirical equation. The results showed that the ANN-based approach outperformed the empirical equation in terms of predictability and error assessment, validating the usefulness of predictive tools in numerical analysis of welding.

Summary: This paper systematically investigated the effects of flux particle size and column height on the bead geometry in submerged arc welding (SAW) process. Experimental data was used to develop regression models to understand the main and interactive effects of process variables. The results showed that both flux particle size and column height significantly influence the bead geometry of the welds.

Summary: In multi-bead and multi-layer arc additive manufacturing process, monitoring the reinforcement of cladding layers in real time plays a significant role. This paper utilizes a point cloud density search method to segment the point cloud of a single weld bead, extracts the reinforcement of each cladding bead, and constructs a residual-based prediction model for real-time forecasting. Experimental results show that the proposed model has great generalization performance and achieves high-precision prediction of cladding reinforcement.
