Welding Inspection & Metallurgy API ICP Self Study Notes

4.1 GENERAL
Welding inspection is a critical part of an overall weld quality assurance
program. Welding inspection includes much more than just the nondestructive
examination of the completed weld. Many other issues are
important, such as review of specifications, joint design, cleaning procedures,
and welding procedures. Welder qualifications should be performed to better
assure the weldment performs properly in service.
Welding inspection activities can be separated into three stages
corresponding to the welding work process. Inspectors should perform
specific tasks;
• prior to welding,
• during welding and
• upon completion of welding,
although it is usually not necessary to inspect every weld.
