Qualification test of welders - Fusion welding - Part 1: Steels
This European Standard defines the qualification testing of welders for the fusion welding of steels.
It provides a set of technical rules for a systematic qualification test of the welder, and enables such qualifications to be uniformly accepted independently of the type of product, location and examiner/examining body.
When qualifying welders, the emphasis is placed on the welder's ability to manually manipulate the electrode / welding torch / welding blowpipe and thereby producing a weld of acceptable quality.
The welding processes referred to in this standard include those fusion-welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automated welding processes (see EN 1418).
Prüfung von Schweißern - Schmelzschweißen - Teil 1: Stähle
Diese Europäische Norm definiert die Schweißerprüfung für das Schmelzschweißen von Stählen. Sie stellt eine Reihe technischer Regeln für systematische Prüfungen von Schweißern auf und ermöglicht so, dass solche Qualifizierungen unabhängig von der Art des Erzeugnisses, des Ortes und des Prüfers/der Prüfstelle einheitlich akzeptiert werden. Wenn Schweißer qualifiziert werden, liegt der Schwerpunkt auf der Fähigkeit des Schweißers, den Elektrodenhalter/die Schweißpistole/den Schweißbrenner so zu handhaben, dass damit eine Schweißung von zulässiger Qualität erzeugt wird. Die Schweißprozesse nach dieser Norm schließen nur solche Schmelzschweißprozesse ein, die als Handschweißen oder teilmechanisches Schweißen bezeichnet werden. Sie schließen nicht die vollmechanischen und automatischen Schweißprozesse ein (siehe EN 1418).
Epreuve de qualification des soudeurs - Soudage par fusion - Partie 1 : Aciers
La présente Norme européenne définit l’épreuve de qualification des soudeurs pour le soudage par fusion des
aciers.
Elle fournit un ensemble de règles techniques pour l’épreuve de qualification systématique des soudeurs, et
permet à de telles qualifications d’être acceptées uniformément, indépendamment du type de produit, du lieu
et de l’examinateur ou de l’organisme d’examen.
Lors de la qualification des soudeurs, l’accent est porté sur l’aptitude du soudeur à guider manuellement
l’électrode, la torche ou le chalumeau de soudage pour produire une soudure de qualité acceptable.
Les procédés de soudage concernés par la présente norme sont les procédés de soudage par fusion
désignés en tant que, manuels ou semi-automatiques. Elle ne traite pas des procédés de soudage totalement
mécanisés et automatisés (voir l’EN 1418).

5.7 Dimensions The welder qualification test of butt welds is based on the material thickness and outside pipe diameters. The ranges of qualification are specified in Tables 5 and 6. NOTE It is not intended that material thickness or outside pipe diameters should be measured precisely but rather the general philosophy behind the values given in Tables 5 and 6 should be applied. For fillet welds the range of qualification for material thickness is specified in Table 7. For test pieces of different outside pipe diameters and deposited thicknesses, the welder is qualified for: thinnest through to the thickest weld metal and/or parent metal thickness qualified (refer to Table 5); and the smallest through to the largest diameter qualified (refer to Table 6).

EN 287-1:2011は、鋼の溶接に関する溶接技術者の資格試験を定義した欧州標準です。この文書は、溶接技術者の資格試験のための一連の技術ルールを提供し、製品の種類や場所、審査者/審査機関に関係なく、その資格を均一に受け入れられるようにします。 この標準の強みは、溶接技術者が電極、溶接トーチ、および溶接ブローピペットを手動で操作し、許容される品質の溶接を生産できる能力に重点を置いている点です。これにより、溶接作業の品質と信頼性を保証し、業界全体での標準化が実現されます。 また、EN 287-1:2011では、手動または部分的に機械化された溶接プロセスに関連する溶接技術が対象であり、完全に機械化されたものや自動化された溶接プロセスは対象外とされています。この点は、溶接技術者の実務的な技能を評価する際に重要であり、実際の作業環境における技術の適用を考慮しています。 この標準は、鋼の溶接分野における重要な指針であり、溶接技術者の資格試験に必要な基準を提供することから、業界の発展に寄与することが期待されます。資格試験の均一化を進めることで、国境を越えた信頼性と品質が確保され、国際的な競争力の向上にもつながるでしょう。
The standard EN 287-1:2011 serves as a comprehensive framework for the qualification testing of welders engaged in the fusion welding of steels. Its scope is well-defined, focusing specifically on the systematic qualification process that ensures a welder's competency in producing welds that meet acceptable quality standards. A notable strength of this standard is its universal applicability; the qualifications obtained under EN 287-1:2011 are recognized independently of the product type, location, or the examining body involved. This fosters consistency in welding qualifications across diverse industrial environments, enhancing the credibility of certified welders. Moreover, the standard delineates specific procedures and technical rules that guide the qualification tests. By emphasizing the welder's manual ability to manipulate the welding equipment-such as the electrode, welding torch, or welding blowpipe-it ensures that practical skills are prioritized. This is particularly beneficial in maintaining high standards in the welding industry, as the quality of a weld heavily relies on the welder's proficiency in manual techniques. While the standard addresses manual and partly mechanized welding methods, it clearly distinguishes itself from fully mechanized and automated processes, as noted in EN 1418. This focused approach allows for a concentrated examination of the skills critical to traditional welding processes-a prevalent requirement in many sectors. In summary, EN 287-1:2011 stands out as a vital standard for the qualification of welders in the realm of fusion welding, providing essential guidelines that promote uniformity, skill validation, and quality assurance in the welding industry.
