焊接体系证书material1.2国外焊接体系认证主要是欧美标准体系，包括EN1090、EN3834、美国AISC、美国CWF、加拿大CWB、CRN认证等。
EN体系认证：EN1090是CE法规中建筑建材指令Directive 89/106/EEC(CPD)下的关于对钢结构的标准。
该标准于01/09/2012开始执行，并于01/07/2014旧标准被完全废除，EN1090开始强制执行。
欧盟规定，在01/07/2014之后，所有进入欧盟市场的钢结构必须要具备EN1090证书，才能被允许在欧盟市场销售。
EN3834是国际焊接学会（IIW）制定的国际性焊接质量体系标准，它规定了金属材料熔化焊接方法的质量要求，用于确保制造商在其焊接活动中取得良好实践以保证焊接产品的质量。
EN3834按质量等级要求不同，分为EN3834-2，EN3834-3,EN3834-4三个部分。
企业可根据具体产品标准、规范或合同，针对质量要求的等级选择相应部分。
北美体系认证：美国AISC认证AISC-American Institute of Steel Construction inc.(美国钢结构协会)AISC是一家总部设在美国芝加哥的非营利性质的技术协会和贸易组织机构，其最初建立于1921年，为钢结构在建筑和其他领域的应用服务。
AISC的宗旨是成为在钢结构相关领域，如规范和编码、研发、教育、技术支持、质量认证、标准化、市场开发上的首选。
AISC为钢结构工业提供及时可靠的技术信息和服务已经成为一项传统，其认证标准称为AISC标准。

欧洲材料及焊接材料标准概况欧洲材料及焊接材料标准概况欧洲标准（EN）被欧盟及其成员国作为该国的国家标准强制执⾏以来，对我国及其他国家在标准应⽤和修订⽅⾯都起了积极的参考和借鉴作⽤。
⽬前欧洲标准越来越受到国际范围的认可，其中⼤多数标准已被等同等效地转化为国际标准（ISO）。
本⽂就部分铁基材料及焊接填充材料的欧洲标准从修订、内容、应⽤和相应的ISO标准之间关的系作概括性介绍。
⼀、部分原材料和焊接材料欧洲标准的制订⼤部分原材料和焊接材料欧洲标准是在1992-1998年间由欧洲标准化委员会起草并制订的，最终由各成员国投票表决，⼀经通过，该标准的原国家标准就将废⽌，执⾏统⼀的欧洲标准。
从内容上看，其来源由三部分组成，⼀部分是前欧洲标准（EU），EU标准是欧盟的主要成员国在四、五⼗年的历史进程中形成的⼀系列标准性的技术⽂件，所以较为熟悉并易被各成员国所接受；如前欧洲标准EU20（钢的概念、分类）转化成欧洲标准EN10020（钢的概念、分类）。
第⼆部分是德国⼯业标准（DIN），由于德国在欧盟中的经济地位和其在冶⾦、焊接技术⽅⾯的出众表现，将DIN标准的内容作为⽬前的欧洲标准。
如德国标准DIN8575（热强钢的⽓体保护焊焊丝）转化成欧洲标准EN12070（热强钢的⽓体保护焊焊丝）；第三部分是将ISO ⽅⾯现有标准等同等效地采纳为欧洲标准，如国际标准ISO13916（焊接时预热、层间和保护温度的测量）转化为欧洲标准EN ISO13916（焊接时预热、层间和保护温度的测量）。
从现有欧洲标准来看，在制订时都尽量采纳或参照现有ISO标准，并在标记⽅法、内容上与ISO标准具有⼀致性，⽐ISO相应标准更细、更具体。

It may be used, where applicable, for other fusionwelding methods or weld thicknesses.Different parts are often produced for different applications but according to similarrequirements. The same requirements should, however, apply to identical parts beingproduced in different workshops to ensure that the work is performed using the samecriteria. The consistent application of this standard is one of the fundamentalcornerstones of a quality assurance system when manufacturing welded structures.9COMPARISON BETWEEN EDITIONS 2 AND 3 9.1IntroductionCrackCrackExternal cracks and internal cracks are not permitted in number 1 of edition 3 ( Cracks).This corresponds with WC and WB in edition 2 for numbers 1, 14 and 25.In number 25 of edition 2 small internal cracks are permitted in welding class WD,which is not the case for the new D class. On the other hand, micro-cracksare permitted in all classes.9.4Crater cracks9.4.1Edition 3 (valid edition)No.DescriptionNo2Crater crackEnd craterA = depth of craterCrater cracks in number 2 of edition 3 correspond closest with numbers 4 and 16 inedition 2 (for butt welds and fillet welds respectively). In edition 3 the crater depth isno longer described. However the crater depth is limited by numbers 15 and 19.Cracks are permitted in class D but not in WD. Otherwise, C = WC and B = WB,where no cracks are permitted.Porosity and gas poresEdition 3 (valid edition)9.5.2Edition 2 (obsolete edition)No.No8Surface porositySurface porosityScattered poresPores in number 3 of edition 3 involves a combination of numbers 8, 18, and 29 inedition 2 (8 and 18 for butt welds and fillet welds respectively have the samenumerical values).Difference between edition 3(valid edition)Total pore area x): D = 4%Total pore area x): C = 2%9.6Localized (clustered) porosity9.6.1Edition 3 (valid edition)NoNo.Description4LocalizedLocalized porosity in number 4 of edition 3 corresponds nearest to number 30 in edition 2.The maximum size of the total projected pore surface or fracture surface is:D =16%C =8%B =4%D9.7Cavities9.7.1Edition 3 (valid edition) (NLTT = Not Larger Than Thickness)No.DescriptionNo5ElongatedElongated cavities in number 5 of edition 3 relates to long or short imperfections forbutt welds and fillet welds.Long imperfections have the most stringent requirements and have no equivalent inedition 2.Elongated cavities related to short imperfections correspond nearest to number 28 inedition 2.9.8Inclusions other than copper9.8.1Edition 3 (valid edition)No.DescriptionNoTungsten inclusionIn number 6 of edition 3, solid inclusions other than copper are related to both longand short imperfections.This imperfection corresponds nearest to numbers 31 and 32 in edition 2, but is notcompletely comparable with these. Special attention should therefore be taken.Copper inclusions9.10Lack of fusion9.10.1Edition 3 (valid edition)No.DescriptionNo8Lack of fusionLack of fusion in number 8 of edition 3 corresponds to number 26 in edition 2.In welding class D interrupted incomplete fusion which does not reach the surface ispermitted. In welding class WD incomplete fusion was not permitted to reach thesurface either, but the size was limited to AIn the two highest welding classes neither of the standards permit incomplete fusion, i.e.C = WC, B = WB.Lack of penetrationEdition 3 (valid edition)Figure AFigure BFigure C9.11.2Edition 2 (obsolete edition)No.No2Incomplete penetrationIncomplete penetrationIncomplete penetrationIncomplete penetration in number 9 of edition 3 relates to fillet welds (figure A), singlesided butt welds (figure B) and double sided butt welds (figure C). The requirementsoriginate from the way the weld designation indicates the penetration depth. Longimperfections of this type are not permitted in any welding class. Short imperfectionscorrespond nearest to numbers 2 and 27 in edition 2.Number 15 in edition 2 does not have an equivalent in edition 3.Figures B and C in edition 3 indicate how much insufficient penetration is permitted,whereas edition 2 indicated how much was allowed to be missing to completepenetration. It is important to be aware of this as both cases are not directlycomparable.9.12Bad fit-up, filler welds9.12.1Edition 3 (valid edition)NoNo.Description10Bad fit-up,Gaps exceeding the appropriate limit may incertain cases be compensated for by acorresponding increase in the throat thicknessNumber 10, bad fit-up, in edition 3 does not exist in edition 2.RemarksSmooth transition is requiredWDUndercuts with A v0,2 t, but max. 2 mm, permitted locally Short undercuts with Amax. 1 mm, permitted locallyUndercut Undercuts withA v0,2 t, but Short undercuts with ANumber 11 in edition 3 corresponds with numbers 5 and 19 in edition 2. However, a smooth transition is required for all three welding classes in edition 3.Edition 3 (valid edition)D: h v1,5 mmC: h v1,0 mmNumber 12 in edition 3, excess weld metal, corresponds with number 10 in edition 2. The main difference is that a maximum height has been indicated in edition 3 for the different welding classes, and that there are requirements for a smooth transition in all classes. Otherwise the following applies:1 mm + 0,25 b, max. 10 mm WD: AIn many cases a throat thickness greater than thenominal value need not be a reason for rejectionNumbers 13 and 14 in edition 3, do not have equivalents in edition 2.9.16Fillet weld throat thickness9.16.1Edition 3 (valid edition)No.DescriptionNo15Fillet weldWD WCLocally -0,2 a Locally -0,1 aThroat thickness deviationNumber 15 in edition 3 corresponds with numbers 21 and 22 in edition 2.In edition 3 the imperfections are referred to as long or short imperfections.Long imperfections are not permitted in any welding class.
