High-strength welded beam body

The utility model discloses a high-strength welding beam body which comprises a cross beam and an elastic unit bearing base, the cross beam is of a vertical plate-shaped structure, shaft sleeves are arranged at the two ends of the cross beam respectively, and the four corners of the elastic unit bearing base respectively extend downwards in an inclined mode to form fixed connecting plates. U-shaped fixing frames located on the front side and the rear side of the cross beam are fixed to the lower surface of the top of the elastic unit bearing base, and the edges of the lower ends of the fixing connecting plates are welded to the side faces of the cross beam in a reinforced mode. And a non-welding area for avoiding welding is arranged below the upper edge of the cross beam. By optimizing the welding position, the influence of a welding area on the structural strength of the beam body in the welding process can be avoided, the fatigue life of the beam body can be prolonged, and metal performance reduction caused
