FSW clamping jig
Clamping system has a huge impact on your weld quality and production rate, so we offer you our know-how for jig design.
Each clamping jig is unique, and requires a high expertise that we are able to provide.
How to clamp your parts during a FSW process?
We first design and manufacture a backing (anvil) that is placed under the part during FSW to support FSW vertical load.
Then we design and manufacture the clamping system to hold the part during welding, providing a 3-axis blocking: a good clamping system permits to avoid part opening, dragging and lifting, which is essential for a good weld quality.

There is a risk that the parts can break or collapse if the forging force is not well handled. The backing of the clamping jig must resist the heat generated by the welding. The right choice of the backing material is key.
The mechanical stops are designed in order to avoid the parts to slip and/or diverge during the Friction Stir Welding process. Moreover, specifics clamps also are put in place to deal with the eventual lifting of the parts.

There are two clamping system types :
Manual
Small batches and prototypes
Automatic
Large series
