PTG to present Powerstir friction stir welding at Aluminium 2022

PTG Powerstir machine

Rochdale manufacturer PTG is to showcase a range of products at this year’s world's leading trade show and B2B platform for the aluminium industry.

Precision Technologies Group will be showcasing its range of Powerstir dual weld-head friction stir welding (FSW) machines at Aluminium 2022 in Düsseldorf, Germany, in September.

Visitors to the show will be able to discover first-hand how, since their launch a little over two years ago, PTG’s dual weld-head FSW machines have become a favoured choice among electric vehicle OEMs. 

Designed specifically for use in the volume production of automotive battery tray floor assemblies from extruded aluminium panels, the company’s dual weld-head process is aimed directly at manufacturers of skateboard chassis structures and ensures that a tight weld-flatness tolerance is achieved during battery tray floor construction.

Sales director, Mark Curran, said: “Since our Powerstir dual weld-head FSW machines were introduced in 2020, they have achieved double-digit sales – quite an accomplishment during such a challenging trading period for manufacturing industry, and testimony to the quality of the technology.

“At Aluminium 2022, we look forward to showing the advantages of our dual weld-head approach to OEMs looking to benefit from advanced FSW processes.”

PTG has been a leading name in the manufacture of friction stir welding machine tools for transport applications for more than 20 years – ever since its first Powerstir FSW machine was launched in 1998 and subsequently won the 2000 Metalworking Production ‘Outright Winner’ and ‘Grand Prix’ awards. 

More recently, however, PTG has used its considerable knowledge of the FSW process to assist automotive OEMs in producing lightweight, robust and aesthetic components for both battery electric vehicles (BEV) and plug-in hybrid electric vehicles (PHEV).
