    压力设备CE认证:焊接工艺评定 PQR(Welding Procedure Qualification)

    欧盟焊接工艺评定PQRWelding Procedure Qualification Record的英文缩写,所以有时也写成WPQR,一般译作“焊接工艺评定报告”。验证所拟定的焊件焊接工艺的正确性而进行的试验过程及结果评价。它的目的在于:

     

    A 对拟出的焊接工艺(WPSWelding Procedure Specification)进行检验,是否具有可操作性、合理性;

    B 焊接材料选用是否正确,焊接工艺参数是否合适;
    C 证明工厂的设备、人员等技术状态的良好性,有能力从事指定的焊接工艺,能获得合乎标准要求的焊接质量。
     

    适用范围:

    1、适用于锅炉,压力容器,压力管道,桥梁,船舶,航天器,核能以及承重钢结构等钢制设备的制造、安装、检修工作。

    2、适用于气焊,焊条电弧焊,钨极氩弧焊,熔化极气体保护焊,埋弧焊,等离子弧焊,电渣焊等焊接方法。

     

    完整的焊接工艺评定程序一般可分为五个步骤:

    1.提出工艺评定项目;

    2.编制工艺评定任务书和焊接规程;

    3.进行工艺评定试验;

    4.编写工艺评定报告;

    5.编制焊接规程以指导生产。
