Stirweld France Europe friction stir welding
Stirweld FSW meets requirements ISO 25239

Cost benefits

Low welding cost: Few consumables (1 tool = welding of 1500-m long),
No material input, no surface preparation, no shielding gas, no gas equipment, low power consumption : 0,2 kWh/m (50% of MIG welding)
Reduction of post-welding inspection
Welding is carried out in a NC machine tool limiting investment
Possible rental of the FSW head to limit the investment.

Product advantages

Welding of all aluminium alloys (1xxx, 2xxx, 4xxx, 5xxx, 6xxx, 7xxx)• Al-Si: easy welding of aluminium foundry, including die casting
High mechanical resistance: weld efficiency of 80-90%, fatigue strength close to the base material
No leakage: water, acid, or air
Excellent thermal and electrical conduction
Forming after welding: stamping or bending of welded parts are possible without cracking
Welding capacity up to 20 mm.

Client advantages

Already democratized in aeronautics, automotive, space, railway and naval sectors

Existing welding standard: ISO 25239

Process advantages

Solution to the shortage of qualified welders.
No surface preparation: no cleaning or grinding is required
The weld is invisible on the back side and requires a small machining on the welding side to remove it if necessary
Replacement of brazing, TIG, MIG or FE welding.
Cold welding (temperature of 400°C): minimal distortion of welded parts, small heat affected zones (HAZ). No spar, no smoke.
Non-toxic: no ozone production compared to arc welding
Welding possible in all positions: no molten pool.

StirWeld aims to democratize the FSW by:

-The drastic reduction of the investment cost
-A catalog of quality and low cost FSW tools
-Support of our experts throughout your industrialization cycle

Since 1995, FSW remains a technology reserved for high added value applications involving expensive equipment.

StirWeld invention uses a NC machine tool for FSW: this innovation drastically reduces the investment cost to FSW while offering performances identical to a special FSW machine.

Stirweld innovation allows companies to optimize their machine fleet and to diversify their technology offer to customers.
