Stirtec GmbH

The FSSW-method is particularly attractive for joining tasks, at which sealing and adhesive media are applied to the surfaces between the components to be joined.

In cooperation with the automotive and engineering industry, Stirtec has developed technical solutions such as our R-SWG (Friction stir spot welding gun), which is capable of being mounted on an industrial robot or stationery on a special chassis as C-SWG (Friction stir spot welding console).

R-SWG (Friction stir spot welding gun)

The Friction Stir Spot Welding Gun R-SWG is a light-weight but powerful machine, which can be mounted on a robot or integrated into a manufacturing center. Combining the latest FSSW-technology with a high-tech force measuring system, the R-SWG offers new possibilites in the field of spot welding. Even different materials like aluminium and steel can be welded together.

Since there is no permanent material pickup on the tool (no alloying), an uninterrupted process becomes feasible. Further, no chemical or mechanical pre-cleaning is necessariy, which reduces the costs of the process drastically.

C-SWG (Friction stir spot welding console)

The powerful Friction Stir Spot Welding Console C-SWG is a powerful unit, which is fully programmable via a CNC tool. Using state-of-the-art FSSW technology combined with a high-tech force measurement system, this console opens up new opportunities for friction stir spot welding (FSSW) of sheet metal. Even different materials such as aluminum and steel can be joined with this machine.

No aluminum build-up (alloying) is formed on the tool, which makes uninterrupted use possible. The chemical or mechanical pre-cleaning can be omitted which brings a significant cost reduction.

Stirtec offers its customers various high-performance FSW machines. This portfolio can be divided into vertical, horizontal and gantry machines. All Stirtec machines have a particularly high rigidity of the machine, are fully automatable and equipped with a Siemens control Sinumerik 840D sl.

In addition, all our machines can be equipped with our maxstir^TM FSW software, which enables real-time measurement and documentation of process forces. This guarantees full traceability.

Depending on the machine type, Stirtec offers automatic pallet changers, parallel loading and unloading, automatic tool changing, extension to hybrid equipment for FSW and milling etc..

Aluminum sheets as well as cast or extruded aluminum components can be welded in butt or lap joint. Typical applications of the Stirtec FSW machines can be found e.g. in the automotive industry and especially in e - mobility for the manufacture of motor housings, battery boxes, power electronics coolers or crash boxes. Here, Stirtec's customers benefit particularly from the high process capability of the machines and the low maintenance and non-productive times.

We are happy to advise you which machine is the right one for your component.

We also gladly offer you the suitable fixtures for the machines.

Currently, we have, among others, the following FSW machines in our portfolio:

Vertical machines

V-FSWC1060 - 1270x590mm

V-FSWC1260 - 1450x590mm

V-FSWC2080 - 2200x780mm

Horizontal machines

H-FSWC630 - 630x630mm

Gantry machines

G-FSWC2318 - 2520x1600mm

As a single-source supplier of FSW technology, Stirtec also offers high-quality tools. Our innovative tool range is based on many man-years of research and development in the areas of process and materials technology.

All of Stirtec’s tools are characterized by high functionality, process reliability and exceptional wear resistance which results in a long service life. Moreover, our tools also enable comparatively higher welding speeds for the respective application areas.

A broad range of material combinations can be welded using Stirtec tools, such as aluminium/aluminium (including high-strength alloys) or different metals, such as aluminium with steel, copper, magnesium or titanium.

Among other things, we offer the following tools:

• qualified maxstir^TM series tools
• FSSW tools
• One-piece tools
• 2-part tools with a fixed probe
• 2-part tools with an adjustable probe
• Bobbin tool

Stirtec supports its customers from idea to implementation. We accompany you from the process of design through to series production. In order to support the customer in the best possible way, Stirtec offers, among other things, the following services:

• FSW workshops (on request with individual dealing of your component)
• Contract R & D
• prototyping
• Qualification and training according to ISO standard
• WPS - Welding Procedure Specification
