A resistance welding head with parallel electrodes includes two parallel electrodes each having an electrode body and an insulation layer through which the two electrode bodies are insulatively secured to each other. An upper electrode tip and a lower electrode tip are disposed at two opposing ends of each electrode body respectively. The two upper electrode tips form an upper welding head tip of the resistance welding head with parallel electrodes, while the two lower electrode tips form a lower welding head tip of the resistance welding head with parallel electrodes. The upper welding head tip is able to weld the welding piece to be welded, and the lower welding head tip may also weld the welding piece.
