Abstract： |
A technology for preparing thermoelectric couple includes such steps as cutting different two metal wires by same length, shearing and gathering their ends for welding them, connecting two outputs of voltage-regulating transformer respectively to other ends to be not welded of said wires and a tin film, putting the tin film in a the incombustible oil, turning on the transformer, contacting the ends to be welded of said wires with the tin film and quickly separating them from each other after arced. |
