Abstract

Cold Metal Transfer (CMT) welding has emerged as a promising technique for joining dissimilar materials, offering enhanced weld quality and mechanical properties. This review article explores the application of CMT welding in joining different metal alloys, focusing on two significant cases: magnesium-aluminium and aluminium-stainless steel combinations. CMT welding minimizes intermetallic compound formation and produces high-strength joints in magnesium-aluminium combinations. CMT welding with a friction-surfaced aluminum coating offers strong metallurgical bonding in aluminum-stainless steel joints. Precise penetration control and superior tensile strength compared to MIG welding are notable advantages. Optimizing welding parameters and understanding microstructure characteristics are crucial for successful CMT welding of dissimilar materials, presenting promising applications across industries. The review also discusses the impact of welding parameters on the properties of CMT-welded joints, emphasizing the importance of optimizing these parameters to achieve desired results

Keywords: Cold Metal Transfer (CMT), Microstructure, Mechanical properties, Dissimilar metals
