Which tool to choose?

FSW TOOLS

Our commitment : to provide you with the right solution for every type of parts and materials.

For the FSW, the quality of the weld is inseparable from the geometry and quality of the tool. The tool therefore has a direct impact on the wear and quality of the weld.

Thanks to the FSW experience of his team, StirWeld offers you the most suitable tool for your use by combining quality, price and reliability.

FSW Stirweld tools are robust and powerful for a controlled cost. Discover our range of FSW tools :

FSW Tools Structure

The FSW tool consists of a shoulder to warm the material by friction and a pawn to stir the components. These two parts are essential elements to guarantee the good mixing of the material and the seamless welding.

The shoulder

is placed on the surface of the parts to be welded. Thus, it rubs on the material and creates the necessary friction heat to “soften” the pieces (about 400 ° C aluminum). The metallurgical phenomenon is close to that of extrusion. In addition, because of its shape and size, the shoulder confines the material and prevents it from leaving the kneaded area.

The pawn enters the parts to be welded

Thanks to its shape, it will both heat the material by shearing effect and ensure the mixing of the material despite the presence of aluminum oxide on the parts. Thus, the choice of a tool adapted to the materials to be welded associated with qualified welding parameters will allow the material to close behind the passage of the tool, to crush the aluminum oxide and to obtain a irreproachable welding.

Tool impact on the mechanical strength of the weld

The strong stirring of the material by the pion and the heat generated by the shoulder cause a phenomenon of recrystallization of the aluminum. This results in the precipitation of fine grains that will contribute to the very good mechanical strength of FSW welds.

6th FSW Symposium – Tool Review

 Our tools can weld all part configurations :

  • Butt (similar or dissimilar thicknesses)
  •  Transparency
  • T-shaped (or welded at an internal angle through the top)

What is the life time of FSW tools?

FSW tools are solicited in two ways :

 

  • Cyclic fatigue at the base of the pion causing premature breakage of the pion. This fatigue is due to the drag force as the tool moves into the room. The latter is particularly high aluminum with high elastic limits (type 7xxx, Al-Cu-Li or aluminum on steel), very demanding for tools.
  • Abrasive wear of the entire tool by friction in the welded material. This stress causes a wear of the forms guaranteeing a good kneading of the material (spiral of the shoulder, length and threading of the pawn).

 

Depending on the materials, we have developed FSW tools allowing a welding distance of more than 1500 m on all our Al / Al tools. We have designed a test bench to optimize the geometry of the tools. tools and their heat treatment to meet these requirements.

What do clients think of STIRWELD?

“The most important thing for our welds is first of all to find the right parameters, we have made several sets of hundreds of parts with Stirweld FSW tools, the welds are clean, reliable and reproducible.”

Alain LOZACH

R&D Manager Cap Profilé, CALIP GROUP

“Already users of FSW technology for the manufacture of our Cobawheels rims, we chose to install Stirweld’s FSW head on the existing machine to develop new FSW applications at lower cost.”

R&D Engineer, SAINT JEAN INDUSTRIES

StirWeld : your FSW tools supplier

Quality commitment

Our FSW tools undergo a demanding quality control and the optimized heat treatment guarantees the consistency of their mechanical properties.

The design of our tools is the result of many years of research.

Stirweld TUV Rheinland

 

Stirweld is a supplier of the most demanding customers in the aerospace, aeronautics and automotive sectors, with catalogue tools or tailor-made tools (Stirweld support during upstream design-to-build phases).

Easy to use

We made the choice of standardizing attachments with the Whistle Notch system. This solution allows for quick insertion and removal of the tool. The axial position is guaranteed, the risk of damage to the housing when the tool change is canceled.
