The invention provides a double-physical-field-assisted single-face laminated metal composite plate manufacturing method. The method includes the following steps that the surface of a base metal plate is cleaned through an acid pickling method, grease, stains and oxidation films are removed, and drying is conducted; the base metal plate is preheated under the atmospheric conditions or nitrogen or argon protection condition, the preheating temperature ranges from 150 DEG C to 1700 DEG C; rolling is conducted on the base metal plate or a base metal plate of preset low-melting-point filling materials through an inner-cooling type water cooling roller, meanwhile, ultrasonic waves and magnetic fields are applied continuously till a single-face laminated metal composite plate is manufactured. The double-physical-field-assisted single-face laminated metal composite plate manufacturing method has the advantages that the ultrasonic waves and the magnetic fields are applied, control over the interface reaction and intensifying of mass transfer process are facilitated, a composite welding seam for intensifying intermetallic compound particles is obtained, welding seam grain is refined, residual stress is lowered, the oxidation films are broken effectively, consumption of brazing flux is lowered or avoided, the toxic and side effect on staff and adverse effects on combined interfaces are reduced, energy saving is facilitated, and the environmental pollution is lowered.
