摘要：
本发明涉及一种电阻点焊电极及其制备方法，属于电阻点焊技术领域。该电阻点焊电极包括第一导体和第二导体，所述第一导体的下端面设有与第二导体外形匹配的凹槽，所述第二导体镶嵌在所述凹槽内，第二导体下端面与第一导体的下端面齐平，第二导体的电阻率大于第一导体的电阻率，所述第一导体的上端面设有冷却槽。本发明的电阻点焊电极用于焊接时，能够提高金属板间的连接强度，制备方法简单方便，制得的电阻点焊电极结合牢固、性能好、强度高。
摘要（英）：

The invention relates to a resistance spot welding electrode and a manufacturing method thereof, and belongs to the technical field of resistance spot welding. The resistance spot welding electrode comprises a first conductor and a second conductor. A groove matched with the second conductor in appearance is formed in the lower end face of the first conductor. The second conductor is inlaid in the groove. The lower end face of the second conductor is flush with the lower end face of the first conductor. The electrical resistivity of the second conductor is larger than the electrical resistivity of the first conductor. A cooling groove is formed in the upper end face of the first conductor. When the resistance spot welding electrode is used for welding, the connection strength between metal plates can be improved; the manufacturing method is simple and convenient, and the manufactured resistance spot welding electrode is firm in combination, good in performance and high in strength.
