Visual testing (VT) is one of the oldest and most widely used NDE methods used to derive a multitude of information from a variety of material characteristics and properties. Visual Examination is used in all stages of manufacturing and fabrication as a means of verifying conformance to standards and ensuring the quality levels are met and maintained in the final project.
AWS QC-1 CWI
MQC Labs visual inspections or visual examination of objects, parts or components, is the oldest and most reliable non-destructive testing method. The test method is applied to almost every product as a quality assurance tool. A visual inspection of a weld joint prior to welding to verify the weld joint design tolerances are being met is the best means of insuring a sound weld. Sloppy weld joint alignment is a primary cause of poor weld quality. Certified weld inspection (CWI) can successfully detect these unacceptable surface discontinuities without applying expensive test methods.
