EN 1321 Destructive Tests on Welds in Metallic Materials - Macroscopic and Microscopic Examination of Welds Test

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 1321 testing. This standard specifies sample preparation methods, test procedures and their main purpose for macroscopic and microscopic examination.

Macroscopic and microscopic examination is often used to reveal the macroscopic and microscopic features of a welded joint by examining cross sections.

This is done by visual or optical inspection of the prepared surface before or after etching. In the case of microscopic examination, higher magnifications are required compared to visual inspection.

The test is generally applied to test specimens oriented perpendicular to the weld axis (cross section), including weld deposits and heat affected zones on both sides of the weld. The location, orientation and number of test pieces should be as specified in the relevant standards or specifications or by special agreement.

The following information will be provided:

• Base metals and consumables;
• The composition of the etcher;
• Surface;
• Etching methods;
• Etching time;
• Additional precautions;
• Any additional requirements;
• The object of the test.
