๐ฅโ๏ธ NO WELDING TORCH. NO FILLER METAL. JUST FRICTION AND EXTREME PRESSURE!
How can two solid steel components become one without conventional arc welding?
The answer is ROTARY FRICTION WELDING.
One metal component spins rapidly while the other is held stationary. Powerful axial pressure forces the surfaces together, generating intense frictional heat.
As the metal softens, material is pushed outward into a distinctive circular flash collar.
Then the rotation stops, and forging pressure consolidates the joint.
