Format: PDFDocument ScopeThis guide essentially provides an introduction to visual examination of welding. These examinations fall into three categories based on the time they are performed, as follows: (1) prior to welding, (2) during welding, and (3) after welding. An extensive treatment is provided on weld surface conditions, including reference to frequently used terminologies associated with preferred and non-preferred conditions. Visual examination may be performed by different people or organizations. Personnel performing welding examination include welders, welding supervisors, the contractor's welding examiner, the purchaser's examiner, or the regulatory examiner. For the purpose of simplicity, these individuals are referred to as visual examiners in the remainder of this standard in that they perform visual examination.
Fabrication documents, contract specifications, and regulatory agencies may specify who performs final examinations.Also provided is a review of visual examination equipment routinely used, such as gauges and lighting equipment. Formal documentation of visual examination results is also discussed. Finally, the guide suggests additional reading or references, that may provide more detailed requirements for specific visual examination applications.AWS A3.0M/A3.0 uses nondestructive examination (NDE) as the standard terminology for these examination methods. In other standards, literature, and industry usage, other expressions are commonly used. Among these are: nondestructive inspection (NDI) and nondestructive testing (NDT). It must be emphasized that all of these expressions are commonly used and may be considered equivalent.
