Evaluation standard for each welder based on the identified parameters of welds shall not be less than 2 groups (6) specimen, and through the tensile strength test in accordance with regulations, to think the inspection qualified. ③受力钢筋接头位置应相互错开，当采用搭接接头时，从任一接头中心到1.3倍搭接长度的区段范围内，有接头的钢筋面积应小于钢筋总面积的25%(受拉区)和50%(受压区)。当采用焊接接头时，在任一焊接接头中心到长度为钢筋直径的35倍且不小于500mm的区段范围内，有接头的钢筋面积应小于总面积的50%。 (3) reinforced joint position should be staggered, when using lap joint, from any joint center to 1.3 times the lap length of segments within the scope of a joint reinforcement area should be less than 25% of the total area (tensile) and 50% (compressive zone). When welding joint is used,
