The invention discloses welding equipment which comprises a fixed machine body. Water storage space is fixedly arranged on the lower side in the fixed machine body. A gear cavity a is fixedly arrangedin the fixed machine body. A shell is fixedly arranged at the position of the upper side of the left end face of the fixed machine body. A drive motor is fixedly arranged in the shell. Chain drive space is arranged on the right side in the fixed machine body in an up-and-down symmetry manner. A gear disc is arranged on the side, away from a rotating shaft, in each chain drive space, a cone disc is arranged on the side, close to the rotating shaft, in each chain drive space, and transmission accuracy is guaranteed. An intelligent system is formed by a control device, a cable wire and an induction device. Position accuracy is guaranteed. A cooling system is formed by the water storage space, a water outlet pipeline, a water pump, a first water pipe, a second water pipe and a water outlet head, and stability of the machining process is guaranteed.
