焊接材料或焊材是指焊接时所消耗材料的通称,例如焊条、焊丝、金属粉末、焊剂、气体、电极、衬垫等。不同的母材和焊接方法适用焊材也不一样,欧盟针对不同材质、不同应用的焊材制定了相应的技术规范标准。焊材出口欧盟各成员国时,需要通过CE认证。
焊材CE认证介绍
焊接成品终应于建筑用途时,需按依据欧盟建筑建材法规Regulation (EU) No 305/2011 ConstructionProducts(CPD/CPR)申请CE认证,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:EN13479:2017 Welding consumables - General product standard forfiller metals and fluxes for fusion welding of metallicmaterials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。
