Our welding is renowned for:
- excellent surface finish
- high static and dynamic strength
- absence of pores
- good formability
RIFTEC - We weld aluminium
RIFTEC’s friction stir welds are stronger and tougher than conventional fusion welds. One of the reasons for this is that with our process, substantially less heat is introduced into the component than with other processes. Instead, we use high process forces, which in turn require firm support of the pieces to be welded. We therefore carefully study every component beforehand to see whether the joint geometry is suitable for friction stir welding.
Our services range from individual consulting with construction suggestions regarding material procurement, essential pre- and post-processing, assembly, the actual aluminium welding and quality inspection up to the logistics of the completed components. All of these services are performed to the most important quality standards. You can of course also simply give us your components and we will return them to you friction stir welded.
Even when time is of the essence, you have RIFTEC at your side as a contract welder! As an independent service provider, we can even do irregular series or production start-ups for you at short notice.
You can also call on us if you experience a sudden increase in capacity or as assurance against production failures.
What we can weld with FSW:
Components can consist of almost any aluminium alloy or of other light and non-ferrous metals such as magnesium or copper. Dissimilar joints such as Al-Cu or Al-Mg can also be welded. We even weld stainless steel to aluminium, if the two material grades and the geometry are a good match.
With regard to component size, it is usually the operating space of the machine that is the limiting factor. We can weld up to 2.9 m in one clamping position; depending on the machine, several successive clamping positions are possible. For multidimensional work, the maximum component height is about 900 mm. At RIFTEC, the penetration depth for FSW ranges from 0.8 to 20 mm, but these are merely guide values – it depends on the alloys in question and the component geometry.
Similarly, the welding speed and the process forces applied greatly depend on the component, the material and the geometry. Nevertheless, depending on the welding plant used, the welding speed can be up to 4,000 mm/min and the force applied up to 50 KN.
Benefit for the environment and the team
we weld without shielding gas and without filler metal
