No examination is more valuable than the one performed using the eyes of an experienced inspector. In fact, many of
the methods simply provide an enhanced or volumetric view for the eyes of the inspector to analyze. Direct visual
examination is the key to ensuring welding operations are performed in accordance with the governing codes and
procedures. Visual examination is performed during in-service examinations of piping, vessels, tanks, boilers, and
other equipment to detect a wide range of conditions and may be supplemented by mechanical
measurements, photography, magnification, or chemical etching or response methods.
Many inaccessible areas can be visibly examined using one of several remote viewing devices available to our
personnel such as videoprobes, zoom cameras, or camera crawlers. We have personnel certified in visual examination
via AWS CWI, AWS SCWI, API Inspector and ASNT Level III VT.
