Short answer: Friction stir welding (FSW) is a solid-state process that rotates a non-consumable pin through the joint to plasticise and forge the metal together — giving porosity-free, low-distortion welds especially prized for aluminium and other hard-to-fusion-weld alloys.
At a Glance
How the Stir Works
A spinning tool’s shoulder heats and the pin stirs the plasticised metal behind it; no melt means no solidification cracks.

Where FSW Wins
Ship panels, rail cars and heat exchangers gain quiet, strong seams; manage heat with Metal Heat Affected Zone Guide, distortion with Metal Welding Distortion Guide, and prep per Weld Edge Prep Guide. Tie strength to Yield Strength Vs Tensile Strength.

Sıkça Sorulan Sorular
A solid-state process that stirs plasticised metal together with a rotating pin — no melting.
Aluminium’s oxide and hot cracking make fusion welding hard; FSW avoids both.
Generally no — without a molten pool there is no gas porosity.
It can, but tool wear is high; steel is usually fusion welded instead.
