标准摘要
[中文适用范围]： 本欧洲标准的这一部分描述了评估车间底漆对可焊性影响的测试。 详细说明了以下测试： a) 评级测试 该筛选测试提供了一种通过进行标准焊接并随后评估所产生的孔隙度的严重程度来评估特定厚度的车间底漆的相对可焊性的方法。 评级测试适用于供应商声明特定车间底漆和类似用途的影响； b) 可焊性测试 该测试描述了使用各种电弧焊工艺评估焊接耗材和车间底漆组合的可焊性的方法。 生产出标准尺寸的圆角，以便进行比较。 对最终焊接的质量进行总体评估。 可焊性测试可能更贴近生产过程中的实际情况。 有关测试期间保护健康、安全和环境的预防措施，请参阅 EN ISO 17652-1。 [外文原描述]： ISO 17652-2:2003 describes tests for assessing the influence of shop primers on the weldability. The following tests are detailed. Rating test This screening test provides a method of assessing the relative weldability of a shop primer of a specified thickness by making a standard weld and subsequently evaluating the severity of the resulting porosity. Rating tests are suitable for declaration by suppliers of the influence of particular shop primers and similar purposes. Weldability test This test describes a method for evaluating the weldability of welding consumables and shop primer combinations, using various arc welding processes. A standard size fillet is produced that enables comparison to be made. An overall assessment of the quality of the resultant weld is made. Weldability tests may be more closely related to actual conditions during production.
