Welding inspectors are employed to assist with the quality control (QC) activities necessary to ensure that welded items meet specified requirements and are fit for their application.
For employers to have confidence in their work, welding inspectors need to understand/interpret various QC procedures and also have a sound knowledge of welding technology.
The relevant standards, rules and specifications that a welding inspector should be familiar with at the start of a new contract are all the documents they will need to refer to during the fabrication sequence in order to make judgements about particular details.
Typical documents that may need to be referred to are:
- The Application Standard (or Code): for visual acceptance criteria. Although most of the requirements for the fabricated item should be specified by National Standards, client standards or various QC procedures, some features are not easy to define precisely and the requirement may be given as to good workmanship standard.
- Quality plans or inspection check lists: For the type and extent of inspection.
- Drawing: for assembly/fit-up details and dimensional requirements.
- QC procedures: company QC/QA procedures such as those for document control, material handling, electrode storage and issue, welding procedure specifications, etc.
