焊接材料CE認(rèn)證

焊接材料在建筑工程行業(yè)非常常見，它其實(shí)就是焊接時(shí)所要消耗的材料的總稱，此類產(chǎn)品在出口歐盟時(shí)需要按照，歐盟的CPR建材指令辦理CE認(rèn)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(duì)不同的材質(zhì)和不同應(yīng)用的焊材制定了相應(yīng)的技術(shù)規(guī)范標(biāo)準(zhǔn)。再根據(jù)這些標(biāo)準(zhǔn)進(jìn)行測(cè)試，測(cè)試通過，歐盟公告機(jī)構(gòu)即可簽發(fā)ce證書。

焊接成品最終應(yīng)于建筑用途時(shí)，需按依據(jù)歐盟建筑建材法規(guī)Regulation (EU) No 305/2011 Construction Products (CPD/CPR)申請(qǐng)ＣＥ認(rèn)證，此外，歐洲標(biāo)準(zhǔn)具有分類較細(xì)、針對(duì)性較強(qiáng)的特點(diǎn)，在應(yīng)用時(shí)注意其前提條件，例如采用手工電弧焊接結(jié)構(gòu)鋼時(shí)的焊條標(biāo)準(zhǔn)有EN499、EN757, EN499適用于材料屈服強(qiáng)度≤500Mpa的強(qiáng)度結(jié)構(gòu)用鋼，而EN757適用于材料屈服強(qiáng)度>500Mpa的強(qiáng)度結(jié)構(gòu)用鋼。如：通用焊材CE認(rèn)證標(biāo)準(zhǔn)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(chǎn)品標(biāo)準(zhǔn)。
