Welding equipment capable of achieving rapid butt joint for machining

The utility model discloses welding equipment capable of being in butt joint quickly for machining, which belongs to the field of machining and comprises a base, a mounting frame, a mounting ring, a mounting pipe, a conical surface, a fixing nut, a fixing screw rod, a connecting rod, a large gear, a power motor and a power gear. When the pipeline welding device is used, two pipelines to be weldedare inserted from the two ends of the two mounting pipes, when the two pipelines abut against each other, a worker screws the fixing screw rods, the fixing screw rods abut against the pipelines underthe action of the fixing nuts to fix the pipelines, then the worker can weld the pipelines, and the welding efficiency is improved. When the other side of the pipeline needs to be welded, the power motor works to drive the power gear to rotate, the power gear rotates to drive the large gear to rotate, then the large gear rotates to drive the mounting pipe to rotate, the connecting rod drives the other mounting pipe to rota
