ABSTRACT:
A method for welding two pieces includes juxtaposing the pieces and monitoring the temperature of the region to be welded. Energy is applied at a time rate sufficient to raise the temperature of the region to be welded at a rate exceeding a predetermined value. Once a predetermined temperature is reached, that temperature is held for a predetermined time. The rate of rise of temperature is 70% of the final or predetermined temperature in 20% of the predetermined time. After the weld is made, the rate of fall of the temperature exceeds a predetermined value. Quenching may be used to achieve the desired rate of fall.
