FSW head for CNC with retractable pin

Welding of your application without exit hole

More info

Friction Stir Welding head with retractable pin

Our friction stir welding head with retractable pin has all the functions of our standard FSW head: force control & recording, cooling, protection of the spindle against loads and vibrations.

The difference is the retractable pin which enables to fill the FSW exit hole, beneficial for aerospace applications for example.

With its HMI, our FSW head with retractable pin results in 100% quality control of welds: FSW force control, pin length control, head temperature & usage, warning pop-up and data recording.

RETRACTABLE PIN: HOW DOES IT WORK?

Friction Stir Welding for copper tube joining

At the end of a friction stir welding operation, the tool pin leaves an exit hole. This exit hole can be a problem in some applications. With the FSW head with retractable pin, this exit hole is filled in.

Indeed, the tool pin is removable. At the end of the welding process it retracts leaving no exit hole.

RETRACTABLE PIN PRINCIPLE

TOOL IN TWO PARTS

The shoulder and the retractable pin are independent for an easy change and cost saving

TORQUE TRANSMISSION

Whistle notch attachment for high torque transmission

The pin and the shoulder are synchronized in rotation speed

ALIGNMENT

Alignment between the shoulder and the pin is made with an H7/G6 tolerance.

  • Display curves of selectable values to control the weld quality
  • Free software update
Friction Stir Welding machine specifications

We wanted to evolve the tool to suit our needs. Before, we used a robot arm to carry out friction stir welding. However, there are many joints in a robot. This makes it too flexible. It deforms a little when you press on the welded surface. In an operation like FSW, you lose precision. To achieve the precision we want, we needed the stiffness of a machine tool.

APPLICATION EXAMPLES

ALUMINIUM TANK WELDED BY FSW

Friction stir welding is one of the technologies that solves many problems in aluminium tank welding.

The conventional technique was arc welding, however, this technique led to poor fatigue and corrosion resistance of the welding zones.

With FSW technology, this problem is solved. In addition, with the FSW head with retractable pin, the fatigue strength of your workpiece increases. Why? Because there is no longer an exit hole.

Also with this FSW shrink-fit head, it is possible to weld different thicknesses without changing tools.

CIRCUMFERENTIAL WELD

Example of AA 2024-T3 circumferential weld (diameter of 500 mm) with retractable pin FSW head. Thickness of 3 mm.

After FSW, the joint efficiency is 85% (ratio between UTS of circumferential weld and UTS of base metal) in accordance with ISO 25235 standard. By comparison, the joint efficiency of TIG welding is 50%. Moreover, the leak property is perfect as FSW is a solid-state welding process without melting pool (no pore, no crack).

For manufacturing of aluminium tanks, a minimum of 2 circumferential welds is necessary to close the component. This type of weldment requires a retractable pin FSW tool to fill the keyhole at the weld end and to not leave a hole that impacts the leak property.
