Pedal Powered Welder: Pedaling through innovation

Talk about pedal power, the inertia welding machine requires just about a little of the human muscle. In this case, one needs just a few men, a bicycle, a car jack, a flywheel from the static steam engine and two aluminium sheets to join. to make an Inertia friction welding machine work. Pedal, pedal and lots of pedal for a few seconds at a speed of 400-450 rpm with a noise could shatter your ear drums. But all this is worth the result; joining of two aluminium sheets with the power of sheer human muscle.
