“…In recent years, propelled by the rapid advancements in intelligent manufacturing, the demand for welding robot arms has surged. They are extensively applied in aerospace, shipbuilding, automotive manufacturing, and other sectors due to their capability to operate in challenging and intricate environments, delivering high welding efficiency and consistent weld quality [1][2][3][4][5]. However, during welding operations, the synchronization of multiple axes within the robot arm can significantly impact welding quality.…”

In order to enhance the synchronization of welding robot arms and improve welding quality, this study proposes a fuzzy PID-based improved deviation coupling multi-axis synchronous control method. Firstly, in response to the intricacies inherent in the compensation mechanism of the deviation coupling control structure and the substantial volume of system computation, the integration of average speed and sub-average speed is proposed to optimize the speed compensator. This integration aims to mitigate speed synchronization errors, minimize synchronization adjustment time, and elevate overall system synchronization performance. Moreover, the fuzzy PID algorithm is employed to design the controller to realize the single-motor adaptive control, leading to improvement in both system stability and dynamic response performance. Finally, a simulation model for six-axis synchronization control and an experimental platform were developed. Both simulation and experimental results demonstrate that the improved deviation coupling control method exhibits superior synchronization performance. The proposed multi-axis synchronous control method effectively heightens the synchronous performance of the six-degrees-of-freedom robotic arm.

“…In this method the flux, applied externally in SAW method is placed inside the wire, allowing the welding process to be carried out at higher current densities. In addition, another important effect of FCAW is that the greater penetration obtained in the MAG method and the faster and cleaner weld deposits obtained in MIG welding are provided in a single method more economically [27][28][29][30][31].…”

In this study, it was aimed to investigate hardfacing weld metals’ metallurgical and mechanical properties produced by flux-cored wire and submerged arc welding flux combinations. The usage of the combination for these two methods, which are generally preferred separately, distinguishes this research from other similar studies. In the first stage, the optimum production conditions and physical properties of the submerged arc welding fluxes were determined and then flux-cored wire manufacturing details have been defined. Agglomerated submerged arc welding fluxes and seamed type flux-cored welding wires samples were investigated according to the changing carbon, chromium, niobium, and wolfram ratios, while manganese and silicon values were kept constant. Five different samples have been prepared with this purpose, and the hardness test, wear test, microstructure analysis, chemical analysis, and X-Ray diffraction analysis were carried out respectively. It was observed that the increase in hardness affects the wear resistance directly. The effect of chemical analyses on the microstructure has also been determined. Moreover, while the increasing amount of chromium carbide clearly changed the microstructure, and the addition of refractory metals enabled the formation of the eutectic and dendritic structure. The problems of low efficiency in flux-cored wire and inability to alloy in submerged arc welding flux were solved with this method. Therefore, the production of hardfacing consumables via submerged flux-cored arc welding combination method was achieved firstly by using domestic raw materials, and one TUBITAK project and one PhD thesis were successfully finished with these data.
