NDE Associates, Inc. provides inspection services for ultrasonic testing. These include Phased array for weld inspection, manual UT-shear wave, thickness measurement, etc. NDT inspections include refineries, petrochemical plants, power plants, utilities, windmills, transmission towers etc,. The inspection is done to detect defects in the welds and to assure that the weld meets the applicable code. The applicable Codes for weld inspection are as follows:

ASME Section V, Article 4, 2010 ed. Ultrasonic Testing of Welds
ASME Section I, Boilers
ASME Section VIII, Pressure Vessels
ASME B31.1, Power Piping
ASME B31.3, Petrochemical Piping
AWS D1.1 Structural Steel

UT Shear Wave in lieu of Radiography for Weld Inspection

Radiography is commonly used to inspect welds that are fabricated as per a specific ASME code. Radiography is a reliable method but it has one major limitation. All work in the inspection area has to be stopped and the workers vacated to avoid exposure. This can impair work progress and delay the job. UT shear wave in lieu of radiography is quite attractive as it does not affect any work being done in the vicinity. Some major companies have chosen UT Phased Array Shear Wave in lieu of Radiography. UT inspection is done strictly as per the applicable code.

NDE Associates, Inc provides consulting services to qualify vendors for inspection as per Code Case 2235-9 or ASME VIII, Div 2 (2010), UT in lieu of radiography. The qualification requires specific requirements including tests on qualification blocks.
