Description

Technical Field

[0001] The utility model relates to the technical field of guardrail welding positioning, in particular to a guardrail welding positioning device. Background Art

[0002] Guardrails are usually made of materials such as metal, plastic or concrete. Depending on different usage scenarios and needs, guardrails can have different shapes, materials and heights. Common types include steel guardrails, aluminum alloy guardrails, plastic-steel guardrails, glass guardrails and protective nets.
