Sigma provides ASNT/CSWIP/PCN Level I, II, & III technicians for Visual Testing (VT) to detect defects and assess weld quality.

VT is a common method of quality control, data acquisition, and data analysis. Visual Inspection, used in facilities maintenance, means inspection of equipment and structures using all human senses (vision, hearing, touch, smell) and/or any non-specialized inspection equipment.

Certified professionals are available for call-out or long-term assignments. Sigma provides turnkey Visual Inspection and reporting services complete with equipment, consumables, vehicles (mileage), and accommodations required to perform VT.
