The utility model discloses a novel
welding structure applied to a water side runner plate and capable of preventing
welding overflow, and relates to the technical field of runner plate
assembly. The device comprises a supporting base, a lifting plate, an upper U-shaped frame, an upper runner plate and a lower runner plate, the top of the supporting base is fixedly provided with three lower U-shaped frames along a center line parallel to the long edge, the lower runner plate is arranged above all the lower U-shaped frames, the upper runner plate is arranged above the lower runner plate, the lifting plate is arranged above the upper runner plate, and the lifting plate is arranged above the lifting plate. Compression springs are fixed to the two short edges of the bottom of the lifting plate, and upper U-shaped frames are fixed to the bottom ends of the two compression springs. Through the arrangement of the supporting base, the lifting plate, the upper U-shaped frame, the upper runner plate and the lower runner plate, the problems that in the water side runner plate
welding process, overflowing is likely to happen, the
fluid circulation stability is affected, clamping force disappears after welding, welding positions are likely to be staggered, and the welding seam quality is affected are solved.
