The standard ensures quality for fusion welding and specifies comprehensive quality requirements. There are requirements for the welding process and the technical evaluation of the welding process, such as the qualification of the welding method, requirements for the welders, inspections and non-destructive testing.

The standard also covers the outsourcing of inspection and testing work, maintenance and inspection of welding equipment, traceability and the way deviations are identified and followed up. In addition to the welding work itself, welding materials, storage of materials and heat treatment are also assessed.

Producers with an ISO 3834 certification have an authoritative, globally recognised certification for welding, welding operations and welding quality procedures. This certification proves Gpi Tanks XL secures all quality requirements in the field of welding activities.
