Battery Tray Floor Construction PTG Announces Multiple Sales of Dual Weld-Head FSW Machines to Electric Vehicle OEMs

Editor: MA Alexander Stark

UK — Just two years after the launch of its range of Powerstir “dual weld-head” friction stir welding machines, UK-based Precision Technologies Group (PTG) reports achieving double-digit sales of these specially developed FSW technologies for electric vehicle OEMs.

Designed specifically for use in the volume production of automotive battery tray floor assemblies from extruded aluminium panels, the PTG’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.

The company's Powerstir range was launched at EMO Hannover some 20 years ago. More recently, however, it has used its 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).

“We are delighted to have achieved this level of sales for our new dual weld-head Powerstir machines in such a short space of time and during such a challenging trading period for manufacturing industry,” comments PTG sales director, Mark Curran.

In addition to building Powerstir machines specifically for the production of battery tray floor assemblies, PTG is also creating FSW techniques for the production of coolant units, control box panels and car body panels, as well as body panels and components for commercial vehicles.

Friction stir welding transforms the parent metal from a solid to a plasticised state. This occurs during a process that involves mechanically stirring the materials to be joined together, to form a high integrity, full-penetration welded joint.
