WHERE FSW TECHNOLOGY MAKES A DIFFERENCE

Friction Stir Welding in Automotive

FSW technology revolutionizes automotive manufacturing with high-quality, lightweight and cost-effective components.

Unlocking Automotive Potential with Advanced FSW Techniques

The automotive industry faces challenges like the urgent transition to electric vehicles, adapting to new consumption models and managing global crises’ impacts. Friction Stir Welding contributes significantly by enabling efficient welding for lightweight EVs, supporting rapid mass production for various mobility services and offering reliable solutions during economic uncertainties. With advantages like high-quality welds, waste reduction and cost-effective production, FSW helps address issues related to competition, sustainability, regulations and standards in the industry.

Navigating Automotive Challenges with FSW Technology

Electric vehicles rely on aluminium and copper to achieve weight reduction and thermal/electrical performance. However, these materials are notoriously hard to weld using traditional methods, often leading to cracks or weak joints.

  • FSW solution: Friction Stir Welding makes it possible to weld aluminium-aluminium, copper-copper, and aluminium-copper joints reliably and without defects. This enables the production of durable and lightweight EV components, unlocking new design possibilities.

Automotive assemblies now demand conductivity, sealing and thermal resistance. Meeting these specifications is key to ensuring safety, efficiency and compliance with perfomance standards in EVs.

  • FSW solution: Friction Stir Welding creates porosity-free, leak-tight welds that meet or exceed strict EV specifications. It supports conductivity and hermeticity – perfect for battery trays, cold plates and bus bars.

Traditional joining methods – incluiding TIG, MIG, screw and joint systems – fail to deliver the consistency, sealing and efficiency required for todays’s EV manufacturing standards.

  • FSW solution: Friction Stir Welding is a solid-state process that avoids fusion-related defects. It offers stronger, cleaner and more repeatable welds, ideal for aluminium and copper applications.

EVs cost up to 30% more to produce than traditional vehicles. Automotive manufacturers must optimize every process to stay competitive – and welding efficiency is a key lever for cost reduction.

  • FSW solution: Friction Stir Welding enables smart scaling: start with a CNC machine and later upgrade to automation. This flexible investment model improves efficiency while minimizing upfront costs.

Exploring FSW Applications in the Automotive Sector

FSW is crucial for e-mobility applications, delivering high-quality welds that support the development of lightweight, efficient and eco-friendly vehicles, while enhancing rapid and cost-effective mass production to meet contemporary industrial and environmental challenges.
