摘要： The disclosed process includes the steps of and upsetting the flashing parts being welded. The flashing is conducted with concurrent measurement of useful electric power and an electric parameter of the flashing process which is related to the power by a function which maximizes the useful power at a predetermined value of said electric parameter. Then the value and sign of the power and parameter increments are determined within one and the same period of time. The parts are brought closer together up to the moment when the ratio of the power and parameter increments reverses ints sign. Then the parts begin to be separated up to the moment when the value of said ratio reaches the preset value selected to suit the welding circuit resistance and the cross sectional area of the welded parts.

摘要： A flash-butt resistance welding process including a flashing of parts being welded and their upsetting. The direction of speed of motion of the parts during flashing is changed by converging and diverging them. The parts being welded are converged up to the moment when the total resistance of elementary contacts arising between the flashed surfaces of the parts becomes equal to 0.4-0.5 of the short-circuit impedance of the welding machine. Then the parts are diverged up to the moment when the summary resistance of elementary contacts reaches 1.4-1.6 of the short-circuit impedance of the welding machine.

摘要： The parts to be welded together are caused to continuously approach each other and their ends are fused by an alternating current, and concurrently an oscillatory motion along the direction of approach is imparted to one of the parts, whereby additional relative movements of the parts towards and away from each other are accomplished. During the stage of a relative movement of the parts being welded together away from each other, the welding voltage is reduced to within the range of 0.7 to 0 of its working value, and during the stage of a relative movement of the parts towards each other, the voltage is restored to its initial value. Reducing the voltage is carried out in a time interval of not less than 1/8 of the period of the oscillatory motion from the beginning of the relative movement of the parts away from each other, and restoring it, in a time interval of not more than 1/8 of the period of the oscillatory motion from the beginning of the relative movement of the parts towards each other. The voltage may be reduced to within the same range for the periods when the resistance across contacts exceeds a predetermined value.
