[0002] Road and bridge guardrails are an important part of traffic safety facilities. They are mainly used to prevent vehicles and pedestrians from falling accidentally, while guiding traffic flow, ensuring driving safety, and preventing vehicles or pedestrians from falling off the edge of bridges or roads. By setting up guardrails, vehicles are guided to travel in the correct direction, reducing traffic accidents. When a vehicle collides, the guardrails can absorb some of the impact force and reduce accident injuries. Road and bridge guardrails are classified by material into composite material guardrails, metal guardrails, and concrete guardrails.

[0003] Existing metal guardrails need to be fixed together by welding. When connecting road and bridge guardrails to guardrail brackets by welding, the horizontal guardrail is usually held by hand and welded between two brackets. However, this method of welding can easily cause the welding position to shift due to hand movement or shaking during welding, affecting the welding effect. Utility Model Content
