<strong>Friction</strong> <strong>Stir</strong> <strong>Welding</strong><br />
<strong>Friction</strong> <strong>Stir</strong> <strong>Welding</strong> (FSW) is a solid<br />
state energy efficient joining technique<br />
with several advantages. HITSPIN TM<br />
<strong>Friction</strong> <strong>Stir</strong> <strong>Welding</strong> equipment<br />
developed by HITACHI, provides welding<br />
solutions for a wide range of applications.<br />
Operating Principle<br />
Process Advantages:<br />
1. Solid State <strong>Welding</strong> Process<br />
No melting of base metal<br />
No loss of alloying element<br />
No fumes or spatter<br />
2. Can easily weld<br />
3D seam<br />
Butt, Lap, T-Joint etc.<br />
3. Simple Process<br />
No shielding gas<br />
No consumables (filler wire)<br />
No surface treatment<br />
Unique features of FSW:<br />
Very low distortion<br />
No porosity or solidification cracking<br />
Weld region has a fine grain structure<br />
than the base metal<br />
Excellent Mechanical properties (strength,<br />
elongation, etc.)
