This article presents a comprehensive study on the application of Hastelloy C-22 powder weld overlay on SA 240 Type 316L austenitic stainless steel using the laser beam welding process. This novel combination of materials and processes was investigated for the first time, focusing on its potential utility for various industrial applications. Various testing techniques, including visual testing, hardness testing, bend testing, chemical composition analysis using optical spectroscopy, corrosion resistance assessment through the potentiodynamic polarization technique, and macro- and microstructural observation, were employed to evaluate the performance of the weld overlay. The research findings had several significant outcomes. Notably, precise control and minimal alloy mixing were achieved, as evidenced by the dilution at a remarkable height of 0.5 mm from the base metal. The laser welding process resulted in a minimal heat-affected zone and a fine columnar interdendritic microstructure, with average primary and secondary arm spacing values of 3.981 µm and 2.289 µm, respectively. Rigorous visual and bend testing confirmed the integrity of the sound welds in the overlay. Moreover, the high-quality finish of the weld overlay eliminated the need for extensive machining and finishing processes, resulting in cost reductions. This study also demonstrated primary and secondary inter-laminar spacing, leading to improved overall structural integrity. Additionally, the weld overlay exhibited excellent hardness characteristics. The current work contributes to the advancement of welding processes and provides practical solutions to enhance efficiency, cost-effectiveness, and structural performance in relevant industrial applications.

In the present work, tungsten inert gas (TIG) welding was carried out on stainless steel pipe joints and the heat transfer behaviour for various welding heat input was analysed. In this work austenitic stainless steel of grade 304L was used and the experiment was carried out on bead on plate and weld profile was analysed. The bead profile was obtained from the experiment and microstructure was characterized. The bead profile dimensions from the experiment were used in the calibration of heat source model during finite element heat transfer analysis. Based on the calibrated heat source model, TIG welding of stainless steel pipes was analysed. Numerical simulation was considered as conduction heat transfer analysis and weld pool convection was neglected in the model. The non-linear transient heat transfer analysis was carried out on pipes and thermal cycles at various locations were analysed.

In the present work, the welding process was using the tubular wire process with pulsed current and gas protection in flat position, SAE 1020 steel base metal and addition metal the martensitic stainless steel 410 NiMo (CA6NM), which has intensive turbine recovery. The purpose was to optimize the welding parameters (average current, pulse rate, welding speed and part contact nozzle distance) in the coating, assisted by the use of first order regression equations in the response variables (process yeld, width, reinforcement and reinforcement area) to predict the results. For the design of the experimental matrix with four variables and three levels, a TAGUCHI method was applied, and the reconstruction of 3D images with a laser device and a web camera, that was adjusted to measure the geometry of the weld bead.The analysis of variance was applied in the results obtained, to statistically prove which variable exerted influence on the response variables, observing that the best performance proceeded for the average current of 230 amps, since statistically the average current was one of the variables of influence that most affected the responses. Therefore, the results of the confirmatory tests with the optimized parameters, showed that the developed models are able to predict the response variables with precision, demonstrating the effectiveness of the TAGUCHI optimization method. The current and voltage signals were obtained simultaneously, and using the Fourier analysis the changes in signal behavior, with frequency and time information that generated the electric arc stability were identified.
