Review on Hybrid Welding Techniques for Improved Joint Performance

Abstract

The process of welding is extensively employed in diverse industrial sectors for the purpose of material joining. The integrity of components or structures is significantly dependent on the quality and performance of welded joints. Nevertheless, conventional welding techniques present certain restrictions, including reduced welding velocity, substandard joint characteristics, and deformation. Hybrid welding techniques have surfaced as a viable solution in recent times to address the limitations and enhance the joint performance.The present study provides a thorough examination of diverse hybrid welding methodologies, encompassing laser-arc hybrid welding, friction stir welding, and hybrid laser welding. The manuscript examines the operational mechanisms, benefits, and constraints of every method. Moreover, the paper presents findings from recent research studies that have examined the collective efficacy of these methodologies across various materials and contexts.The findings indicate that the utilisation of hybrid welding methods has the potential to enhance joint performance through the improvement of mechanical properties, reduction of defects, and minimization of distortion. The manuscript additionally examines the obstacles and prospective avenues in the realm of hybrid welding. The research presented herein offers significant insights for both researchers and practitioners operating within the welding industry. Specifically, it provides guidance on the selection of optimal welding techniques for applications, as well as the optimisation of welding parameters to enhance joint performance.
