Technical principles of Friction Stir Welding

The welding joint is rotating, heating and moving on the surface of the product, high temperature makes the material soften, and the welding seam is weld by joint.

Typical friction stir welding in product surface

FSW seam in the material surface (cross section)

a: Welding area

b: Heat joint affected area

c: Heat affected area

d: Material

No bubble and flawless in weld seam.

Smooth surface, welding performance is good.

  Friction stir welding feature:

1. Simple welding: automation, No pretreatment, No protection gas

2. Environment protection: No smoke, Nonradiative

3. Automation of welding: Similar to milling machine, Easy to operate the machine, Automatic welding, Low noise & No pollution.

4. Small shrink & small deformation

Suitable for various forms of welding

FSW welding joint performance

Comparison of impact toughness (5083 is LF4)

AL FSW joint performance (7075,2014,2219/5083)

FSW vs MIG, Deformation comparison

FSW strengths

Soild state welding technology, no filler, with excellent connector performance.

Can be welded aluminum, copper, magnesium and other nonferrous alloys non-ferrous metals.

This method is highly automated.

Very suitable for aluminum or copper liquid cooling plate welding.

FSW in liquid cooling plate

FSW technology is wildly used in high power machine, aviation, telecom, military and etc.

In liquid cooling plate, traditional welding method is brazing, electron beam welding and etc, but this welding method can not do well in both good sealing and good pressure performance, so there are high defect rate. But FSW can do better in good sealing and good pressure performance, so FSW technology is using for liquid cooling plate.

FSW process in machining liquid cooling plate

FSW Liquid cooling plate structure

Leaking test

Pressure: 2MPa, no leaking in 15 min

FSW Pressure: 4MPa, no leaking in 20 min, better performance

Calculation: In 15mm cold plate, FSW 1mm structure can bear at least 10 MPa pressure.
