Introduction
介绍
The ability of a welder to follow verbal or written instructions and verification of a person's skills are important factors in ensuring the quality of the welded product.
焊工按口头或书面指示进行操作的能力，以及焊工技能的验证，是确保焊接产品质量的重要因素。

The testing of a welder's skill in accordance with this standard depends on welding techniques and conditions used in which uniform rules are complied with, and standard test pieces are used.
按本标准对焊工进行的测试，取决于按统一规则所使用的焊接技术和条件，以及所使用的标准测试件。

The principle of this standard is that a qualification test qualifies the welder not only for the conditions used in the test, but also for all joints which are considered easier to weld on the presumption that the welder has received a specific training and/or has industrial practice within the range of qualification.
本标准的原则是，资格考核能证明焊工不仅胜任在测试中所使用的条件，假定焊工接受到特殊的训练和/或在资格范围内具有工业实践，还能胜任更容易焊接的所有接缝。

The qualification test can be used to qualify a welding procedure and a welder provided that all the relevant requirements, e.g. test piece dimensions, are satisfied.
假如满足了所有相关要求，如，测试件尺寸，资格考核可用于考核焊程序及焊工。

Qualifications in accordance with EN 287-1 existing at the date of publication of this standard should, at the end of their period of validity, be interpreted in accordance with the requirements of this standard.
按EN 287-1考核的资格证书，在本标准出版之日仍存在的，应在其有效期期满之后，按本标准的要求进行说明。

1 Scope
1 范围
This European Standard defines the qualification test of welders for the fusion welding of steels.
本欧洲标准规定了钢氧炔焊焊工的资格考核。

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.
它为焊工的系统资格考核提供了一组技术规范，并使这种资格一致适用于产品类型、位置和主考人/主考组织。

When qualifying welders, the emphasis is placed on the welders ability to manually manipulate the electrode/ welding torch/ welding blowpipe and thereby producing a weld of acceptable quality.
在考核焊工时，重点应考核焊工动手操作电焊条/焊枪/气焊吹管，由此制造出质量合格的焊缝的能力。

The welding processes referred to in this European 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).
本欧洲标准中所提及的焊接工艺，包括指定为手动或部分机械焊接的氧炔焊。
