焊接材料CE认证-EN 13479:2017

焊接材料CE认证

焊接材料在建筑工程行业非常常见，它其实就是焊接时所要消耗的材料的总称，此类产品在出口欧盟时需要按照，欧盟的CPR建材指令办理CE认证，不同的母材和焊接方法适用焊材也不一样，所以欧盟针对不同的材质和不同应用的焊材制定了相应的技术规范标准。再根据这些标准进行测试，测试通过，欧盟公告机构即可签发ce证书。

焊接成品最终应于建筑用途时，需按依据欧盟建筑建材法规Regulation (EU) No 305/2011 Construction Products (CPD/CPR)申请ＣＥ认证，此外，欧洲标准具有分类较细、针对性较强的特点，在应用时注意其前提条件，例如采用手工电弧焊接结构钢时的焊条标准有EN499、EN757, EN499适用于材料屈服强度≤500Mpa的强度结构用钢，而EN757适用于材料屈服强度>500Mpa的强度结构用钢。如：通用焊材CE认证标准为：EN 13479:2017 Welding consumables - General product standard for filler metals and fluxes for fusion welding of metallic materials焊接消耗品.金属材料熔焊用填充金属和焊剂的一般产品标准。
