Then, the blanking jaw 409 clamps the main material 80 under the action of the blanking and clamping cylinder. Then the horizontal feeding cylinder 401, the vertical feeding cylinder 405 and the clamping cylinder work together to transport the main material 80 at the welding position away from the welding position. It can be understood that, at this time, the main material 80 and the auxiliary material 90 have been welded together, so the main material 80 and the auxiliary material 90 are transported away from the welding position together. So far, the flexible controlled butt welding equipment has completed the welding operation of the main material 80 and the auxiliary material 90 .
