焊接钢筋（WWR）是一种预制钢筋，由高强度冷加工钢丝组成，通过连续自动焊接机以方形或矩形网格电阻焊接在一起。本报告提供了WWR产品信息、材料规范和设计/详细建议，并概述了混凝土施工的各种应用中的制造、运输和施工用途。

Welded wire reinforcement (WWR) is prefabricated reinforcement consisting of high-strength cold-worked steel wires that are resistance-welded together in square or rectangular grids by continuous automatic welders. This report provides WWR product information, material specifications, and design/detailing recommendations, with an overview of manufacturing, shipping, and construction use in various applications of concrete construction.
