Certification of Welding and Brazing Procedures

The qualification of a welding procedure arises from the need to verify the validity of a specific welding procedure, certifying the mechanical characteristics of the joint based on the type of base material, filler material, and welding process used. It demonstrates the welding capabilities of a company.

Certification Process

The certification process for welding and brazing procedures involves the following steps:

1. Acceptance of the economic offer.

2. Submission of the certification application.

3. Qualification activities, including a practical test and the required laboratory tests.

4. Deliberation and issuance of the certification.

The qualification activity involves the execution of one or more sample tests representative of the production, overseen by qualified inspectors from I-WELD.

The choice of the representative sample test is often dictated by various conditions such as the execution location, available equipment, joint geometry, acceptability criteria, material thicknesses, and diameters to be welded, as well as accessibility.

Destructive and non-destructive tests required by standards are carried out at laboratories accredited by I-WELD. If all tests are positive, a qualification procedure report is issued.

Qualification activities can be conducted directly at companies or at facilities equipped both technically and for safety.
