The invention relates to a method for assisting hydrogen diffusion of a forge piece based on an ultrasonic-direct current energy field, which utilizes an external ultrasonic-direct current energy field to assist hydrogen diffusion of metal and comprises the following steps: S1, putting a workpiece subjected to heat treatment on a support frame in a water tank; s2, two sides of the metal workpiece are connected with wires, the other ends of the wires are connected with a direct-current power supply, and the power supply is turned on; s3, a salt solution medium is injected till the workpiece is immersed; and S4, ultrasonic transducers are fixed to the two sides of the water tank, the ultrasonic transducers are started, and hydrogen discharging is conducted. After being treated by the method, most of hydrogen atoms in the metal can be effectively eliminated in a short time, so that the metal recovers the original elongation rate, the strength of the metal after hydrogen filling is retained ...
