Process qualification/certification

Processes such as cutting processes, welding processes or also brazing/soldering processes can be certified in different areas of application and according to various standards. In addition to the requirements from the subject-specific standards, as listed in Table 3, it is often necessary to take account of the supplementary requirements from the product standards too. 

A lot of qualifications, e.g. for thermal cutting processes according to DIN EN 1090‑2, welding procedure and welder qualification tests as well as suitability tests for reinforcing steel, are associated with materials tests. Here, we offer you the complete range of destructive and non-destructive materials tests. Our in-house experts in the various subject areas are at your disposal also for advice in these fields and during the monitoring of the qualification processes.

Table 3: Overview of technical specifications for process qualification/certification procedures

EN ISO 9013 Classification of thermal cuts - Geometrical product specification and quality tolerances
EN 13134 Brazing - Procedure approval
EN ISO 15613 Specification and qualification of welding procedures for metallic materials - Qualification based on pre-production welding test

EN ISO 15614-2/AC Arc welding of aluminium and its alloys
EN ISO 15614-4/AC Finishing welding of aluminium castings
EN ISO 15614-5 Arc welding of titanium, zirconium and their alloys
EN ISO 15614-6 Arc and gas welding of copper and its alloys
EN ISO 15614-7 Overlay welding
EN ISO 15614-8 Welding of tubes to tube-plate joints
EN ISO 15614-11 Electron and laser beam welding
EN ISO 15620 Welding - Friction welding of metallic materials
EN 15648 Thermal spraying - Component-related procedure qualification

We carry out process qualification/certification procedures in the following areas of application:

  • Directive 97/23/EC (Pressure Equipment Directive) as a qualification testing body appointed according to Article 13 for permanent joints which are manufactured by welding or brazing/soldering
  • Federal State Building Regulations of North Rhine-Westphalia as a qualification testing body for the checking of manufacturers of certain construction products and of users of certain construction types according to Section 17, Paragraph 5 of the Model Building Regulations (MBO) for cutting, welding and brazing/soldering processes as well as for thermal spraying
