焊接材料在建筑工程行業非常常見,它其實就是焊接時所要消耗的材料的總稱,此類產品在出口歐盟時需要按照,歐盟的CPR建材指令辦理CE認證,不同的母材和焊接方法適用焊材也不一樣,所以歐盟針對不同的材質和不同應用的焊材制定了相應的技術規范標準。再根據這些標準進行測試,測試通過,歐盟公告機構即可簽發ce證書。
焊接成品最終應于建筑用途時,需按依據歐盟建筑建材法規Regulation (EU) No 305/2011 Construction Products (CPD/CPR)申請CE認證,此外,歐洲標準具有分類較細、針對性較強的特點,在應用時注意其前提條件,例如采用手工電弧焊接結構鋼時的焊條標準有EN499、EN757, EN499適用于材料屈服強度≤500Mpa的強度結構用鋼,而EN757適用于材料屈服強度>500Mpa的強度結構用鋼。如:通用焊材CE認證標準為:EN 13479:2017 Welding consumables - General product standard for filler metals and fluxes for fusion welding of metallic materials焊接消耗品.金屬材料熔焊用填充金屬和焊劑的一般產品標準。
