I-STIR Plug Welding System

Category: Robotics > Other > Other
Reference # : Model No :

Friction stir welding equipment produces welds by rotating a non-consumable tool to locally soften a work piece, through heat produced by friction and plastic work, thereby allowing the tool to stir the joint surfaces.


•Good mechanical properties in the as-welded condition
•Improved safety due to the absence of toxic fumes or spatter of molten material
•No consumables (no filler gas shield)
•Process is easily automated
•Lower set up costs
•Less training
•Can easily weld joint geometries and complex curvatures
•Minimal distortion of joined parts due to welding below the melting point
•Low environmental impact



Friction stir welding uses virtually no consumables and generates no harmful fumes. This is because the welding process does not require any filler metal or shielding gas, so no harmful emissions are created.
