AluStir offers technical advice in the field of welding and joining technology as well as turnkey solutions for welding machine procurement.

We are happy to advise you on the welding and joining processes described in the sections of our website, in particular on the welding of aluminium using Friction Stir Welding - hence the name AluStir.

We do not do this alone, but in a network developed over many years with companies specialising in welding technology:

  • AluStir is the sales representative of TWI Ltd (The Welding Institute) for consultancy and research and development services in Southern Germany, Austria and Switzerland.
  • AluStir has been working with Stirtec GmbH in Premstätten on the topic of friction stir welding since 2016.
  • As an international sales representative of the South Korean U-JIN TECH CORP, we offer first-class friction welding machines.

Please contact us without obligation by phone (+49 6024 636 0123) or e-mail ( if you want to participate in the aiCAMstir project or if you are interested in advice from AluStir or in the products and services of one of our business partners.
