Welding procedures

Standards such as ISO 3834, ISO 9001 and EN 1090-2 state that quality management should identify and plan the production processes that directly affect quality. The processes should be carried out under controlled conditions. This applies in particular to processes that cannot be verified by subsequent inspection and where deficiencies become apparent only after the product has been put into use. Welding is such a process where specific welding procedures may be needed.

Qualification of welding procedures

Welding procedures can, depending on the application of the product and the geometry of the welded joint, be qualified in different ways, e.g. according to the following standards:

  • SS-EN ISO 15614 Welding procedure qualification
  • SS-EN ISO 15613 Drop weld test

It is very important to decide, before production starts, which method a WPS should be qualified according to, when qualification requirements exist. The use of a specific method to authorise a welding procedure is often a requirement in the design rules or a requirement from the customer, authority or the manufacturer itself.

Accredited qualification of welding procedures according to SS-EN ISO 15614-1/SS-EN ISO 15613.

A welding procedure check always starts with the preparation of a preliminary welding procedure sheet (pWPS) according to ISO 15609.A standardised test piece (15614-1) or a production-like welded joint (15613) is welded under the supervision of Inspecta according to the preliminary welding data sheet. Inspecta then performs destructive and non-destructive testing of the specimen. The results of the testing together with the monitoring data are reported in the form of a WPQR (Welding Procedure Qualification Report). The WPQR specifies the validity ranges within which WPSs can be prepared.
