Friction welding in slow motion shows two metal parts being rubbed together at high speed. The friction generates intense heat at the contact surfaces, making the metal soft (but not melted). Once softened, the spinning stops, and the parts are pressed together firmly, forming a solid bond. In short: Heat from friction softens the metal, then pressure fuses the parts together without melting them. . Follow @thatisnewton ,All credits to respective creators/owners.
