Description 
The Ultrasonic Testing Procedure is a ready-to-use document defining the requirements and methodology for manual A-scan ultrasonic examination using the pulse-echo contact technique. It covers detection, evaluation, sizing, and characterization of discontinuities in welds and base materials, ensuring consistent and reliable UT execution in accordance with international standards and project quality requirements. 

Key Benefits 

• Standardized UT methodology for manual A-scan examinations 
• Covers straight beam (0°) and angle beam shear wave techniques 
• Fully aligned with major international codes and standards 
• Ensures reliable defect detection, evaluation, and sizing 
• Ready to use and easily integrated into project ITPs and QMS
