“…Among such techniques, in addition to the use of electrodes arranged transversally, the use of strip-shaped electrodes stands out. According to Brien [4], the strips are available in different sizes and usually range from 30 mm to 90 mm in width, with a thickness of 0.5 mm; according to Chattopadhyay et al [5], they result in weld beads with an approximate 20% dilution. In this context, according to Timofeev et al [6], due to its characteristics of low dilution and high productivity, the SAW with strip electrodes is one of the main processes used in corrosion-resistant cladding of equipment produced for the nuclear power plant industry.…”

The present work investigated the effects of a submerged arc welding process with high weaving amplitudes (up to 40 mm) on the weld beads morphological aspects. For this purpose, bead-on-plate welding tests with different welding energies and weaving parameters were performed. As a result, weld beads of up to 45 mm width, free of discontinuities, and with at penetration pro les were obtained.Based on this, we have a single wire process able to ll grooves more e ciently and, at the same time, working for cladding applications.

“…However, the primary considerations include achieving a highquality finish, minimizing dilution, and maximizing the deposition rate. Commonly used conventional welding processes for filling strip back weld overlay and grinding/chipping the bottom side area include SAW, GTAW, SMAW, and MIG/MAG [33]. Among these, SMAW is frequently utilized in small-scale and medium-scale industries.…”

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.

“…A wide range of filler metals is available for wearresistant layers. They are produced in the form of wires or powders and are suitable for hardfacing not only by arc welding methods (GMAW, GTAW) but also by laser or electron beam [10][11][12][13][14][15].…”

The work aims to evaluate the possibility of increasing the resistance of 50MnSi4 steel to wear by hardfacing Fe-Cr-C-Mo type alloys. For this purpose, two types of filler metals for gas metal arc welding (GMAW) were used -Carbofil A 350 and Magmaweld FCH 360. Metallographic evaluation of the hardfacing structure was performed on the prepared samples, supplemented by hardness measurement. Standard tribological tests were used to test adhesive and abrasive wear resistance. The test results clearly showed that the types of filler metals used for weld cladding significantly increased the resistance of the 50MnSi4 steel substrate to adhesive and abrasive wear. When evaluating the adhesive wear, the positive effect of the hardfacing was manifested not only by a decrease in the weight loss of the samples but also by the coefficient of friction. In the case of the evaluation of resistance to abrasive wear, the best indicators were found in the application of the filler metal Magmaweld FCH 360, where the highest hardness of the martensitic structure of the hardfacing 719 HV0.2 was noticed.
