La importancia de los procesos de soldadura en aleaciones ligeras de aluminio y aluminio-litio para la electromovilidad

Resumen

Electromobility has increased the use of lightweight aluminum and aluminum-lithium alloys in the automotive industry due to their high strength-to-weight ratio, recyclability, and contribution to energy efficiency. However, the structural performance and safety of electric vehicles depend directly on the welding processes used in the manufacture of critical components such as chassis and battery trays. This informative article analyzes the relevance of gas tungsten arc welding (GTAW) and laser welding in joining these alloys. The main metallurgical challenges associated with aluminum welding are discussed, including porosity, hot cracking, and heat input control, as well as the technological strategies developed to mitigate them. Finally, the social impact of these processes is highlighted, as they enable lighter, safer, and more sustainable structures, contributing to the reduction of emissions, increased vehicle safety, and the widespread adoption of electric mobility.
