A given part may have several different weld classes. Each weld class is associated with all of the following conditions:  implementation before manufacturing;  follow up during manufacturing;  inspection on welded assembly;  acceptance criteria. The design authority shall insure that inspection requirements are adequate to demonstrate compliance with the design requirements. 6.1.2 Repair The repairer shall comply with the requirements of the design authority. 6.2 Welding machines The machines used for welding shall comply with EN ISO 14744-1. In particular, machines shall have undergone specific qualification tests for use in the aerospace industry when they were acquired or renovated.

Operator qualification shall comprise technical training on the process and production of a manufacturing test specimen, according to a given welding procedure specification and have correctly produced at least one welded part. Production of the manufacturing test specimen according to a given parameter welding procedure specification shall be renewed each time the operator has not welded for more than six months. Technical training on the process shall be repeated at least once every two years according to ISO 24394. SIST EN 4677-001:2012
