The utility model discloses a high-strength steel anti-collision beam. Circular tubular beam, the transition pipe beam, the runway section pipe beam and the connecting wing form a complete section ofhigh-strength steel anti-collision beam; the high-strength steel anti-collision beam is gradually transited to be in a runway shape from a round shape along the axial section, the centers of the roundtubular beam and the runway type tubular beam coincide under the orthographic projection, the bottom sides of the side projections are located on the same straight line, the round tubular beam, the transition tubular beam and the runway type tubular beam are each provided with a weld joint in the axial direction, and the welding process is ERW welding. The connecting wings and the runway sectiontubular beam are connected together through argon arc welding. The weld joint is arranged in the inverted-cone-shaped containing cavity, due to the fact that the containing cavity is narrow in the lower portion and wide in the
