The present invention relates to a soldering material, a preparation method thereof and a soldering method with the soldering material, which belong to the preparation methods and applications of soldering materials. The present invention resolves the problem that the connection strength and the working temperature are low after the prior Ti(C, N)-based cermet is connected with a metal, thus realizing the firm connection between the Ti(C, N)-based cermet and steel, and ensures that the joint has good connection strength and a high working temperature. The mass percentage of the ingredients ofthe soldering material of the present invention is as follows: 40 percent to 45 percent of Cu, 20 percent to 25 percent of Ag, 21 percent to 23 percent of Zn, 5 percent to 10 percent of Ni, 1 percentto 3 percent of Ti and 1 percent to 5 percent of Si. The preparation method includes the following steps: mixing, pressing, sintering and rolling, rolling the soldering material into a soldering material sheet. The soldering method with the soldering material includes the following steps: presoldering preparation, assembly, temperature increasing and temperature decreasing. The soldering materialand the soldering method which are adopted by the present invention successfully realize the firm connection between the Ti(C, N)-based cermet and 45 steel, the maximum room-temperature shearing strength of the joint reaches 268.5MPa, and the average shearing strength reaches 240.9MPa.
