摘要： A method of friction welding wherein the parts to be welded, of materials with inherent Young's moduli, are jigged coaxially, set to rotate with respect to each other under an axial pressure recurrently varying with a frequency which is in inverse proportion to the lower value of the Young's moduli and to the diameter--or to the smaller diameter--of the parts while these are being heated up for welding, whereby, the value of the frequency varies over a range between + and -15% and the parts are then upset-forged together.

摘要： An electromagnetic power drive for a friction welding machine, comprising a magnetic core installed immovably, which carries a power coil connected to a voltage regulator made as a switch and at least one pickup coil connected to an integrator producing voltage proportional to the actual value of the magnetic flux during friction welding, which is connected to a comparison means comprising two comparators, a driving input of one of said comparators receives voltage proportional to the assigned value of the magnetic flux during friction welding, the driving input of the other comparator receives voltage proportional to the other assigned value of the magnetic flux, and a control signal generator having a hysteresis-loop output characteristic, which is connected to the comparators, the output of said generator being the output of the comparison means electrically coupled with the voltage regulator.
