<p>Disclosed is a novel parallel electrode welding head, comprising a parallel embedded electrode welding head provided with two embedded electrodes (101, 102). The parallel embedded electrode welding head comprises main body portions (106), electrode tip portions (107), and embedding transition portions (108), wherein the main body portions are portions of embedded bodies (103, 104) of the embedded electrodes, the electrode tip portions are portions of parallel electrode welding head tips of the embedded electrodes made by means of extending electrodes, and the embedding transition portions are portions of the embedded electrodes embedded in the embedded bodies and extending to the electrode tip portions. Further disclosed is a preparation process for a parallel electrode welding head. Due to the embedding transition portions of the parallel electrode welding head being bent inwardly relative to each other, the two electrodes are significantly thickened, the space between the two electrodes is significantly increased, the angle formed by means of the tip of the electrodes being in contact with each other is significantly increased and the contact distance is significantly lengthened, such that the contact force of the electrode tips can be significantly increased, the stability of the welding head tips and the ability to resist impact are enhanced and the service life of the welding head is prolonged.</p> |
