Aluminium Sections

High thermal conductivity, low weight, high stability, these properties make aluminium a highly demanded material for many industries. Being weatherproof and durable, aluminium sections are, for example, commonly used when installing railing constructions.

However, the low melting point of only 660°C holds difficulties when welding the light metal. Common welding methods with high process temperatures can cause the aluminium to go into a liquid or even gaseous phase. Thus created welding joints are usually warped or untight.

Thanks to Friction Stir Welding aluminium sections can be welded easily and precisely!

By the use of frictional heat, the metal is heated up to just below the melting point and is stirred together at the joints – this leads to firm and tight seams without welding distortion.
