E-Mobility

Accelerating the transformation to sustainability

The automotive industry is currently experiencing a transformation following new requirements for lightweight construction and electromobility. Original Equipment Manufacturers (OEMs) and Tier-1 suppliers find themselves continually confronting new part designs that demand innovative manufacturing processes. Battery Management Systems (BMS) monitor and control the temperatures during the charging and discharging processes of the battery. As they are integrated into the coolant circuit for regulating the temperature of the battery, these circuits of battery trays, stator housings and heat exchangers require a watertight and gastight connection. In the production of vehicle components from heat-treated aluminum alloys, Friction Stir Welding achieves very high strength due to its low heat input.

CHARGING SYSTEMS / BUSBARS

Electric vehicle battery design with exceptional efficiency

Following the transformation within the electromobility, flat busbars can be placed more space-efficient in electric vehicles than cylindrical cables. Due to their larger surface area, the heat input is controlled better. The demand for connecting the lithium-ion batteries to dissimilar materials such as aluminum requires innovative spot-welding techniques. Negative batterie poles are often made out of copper - the positive batterie pole from aluminum material, making them difficult to connect with traditional fusion welding methods. RFSSW (Refill Friction Stir Spot Welding) and FSSW (Friction Stir Spot Welding) are used, among other applications, for aluminum-copper hybrid connections in electromobility. This is especially relevant when a large cross-sectional area of the joint is needed for low-resistance power transmission.

ENERGY TRANSMISSION

Joining for hydrogen

Friction stir welding (FSW) is increasingly being used in energy technology for pipes and pipelines made of high-strength steel. Following highest requirements for hydrogen and sour gases, Stirtec is providing a gastight connection between the materials, crucial in industries such as oil and gas department. Market launch/feasibility using the patented Stirtec technology for Friction Stir Welding of pipeline steels has already proven their highest quality and process-reproducibility to well-known companies in the market.
