Weld Inspection
Advanced Ultrasonic Weld Inspection with PAUT, FMC and TFM
Weld inspection requires more than detecting an indication. Inspectors must achieve reliable weld-volume coverage, maintain sensitivity across the region of interest, distinguish relevant reflectors from geometry, and generate data that supports accurate characterization and sizing.
TPAC combines the Explorer Max ultrasonic acquisition platform with Prelude weld inspection software to support advanced encoded and automated inspections using Phased Array Ultrasonic Testing (PAUT), Full Matrix Capture (FMC), Total Focusing Method (TFM), Plane Wave Imaging (PWI) and adaptive imaging techniques.
Built for demanding weld configurations, high acquisition rates and advanced reconstruction workflows, the solution helps inspection teams collect clear, rich and fully encoded ultrasonic data without compromising inspection productivity.
Application of PAUT in Weld Inspection
With a variety on non-destructive testing techniques available, ultrasonic inspection (UT) is the preferred method. Within this technique, phased array UT (PAUT) has emerged as a powerful tool, offering several advantages over traditional inspection methods.
By employing multiple advanced tools, PAUT enhances defect detection and characterization while providing real-time feedback, ultimately improving the efficiency and accuracy of weld inspections.
WHAT ADVANCED IMAGING CAN DO FOR WELD INSPECTION
Advanced imaging technologies such as Full Matrix Capture (FMC), Plane Wave Imaging (PWI), Total Focusing Method (TFM) and multiple others greatly improve the detection and sizing of the defects that can be found in weld that include:
cracks, lack of fusion, porosity, incomplete penetration, and slag inclusions.
Better and more accurate sizing allows for less false calls and engineers can apply defect characterization and risk assessment criteria.
The latest technologies such as Adaptive TFM (ATFM) furthers pushed the boundaries of ultrasonic inspection allowing for imaging below the weld cap, an area very difficult or even impossible to reach using other methods.
Paired with Prelude, check how the Explorer Max delivers fast results on the most challenging surfaces in the oil & gas and power generation industries.
TPAC – An advanced selection of ultrasonic acquisition tools
Whether it is for butt welds, fillet welds, or other configurations found in pipelines, pressure vessels, structural components, we offer the tools to inspect the most challenging welds.
The Explorer, available in configurations ranging from 16/64 to 128/128 and 64/256, provides all the firepower and range you need to address any weldment, from 0.25” to 2” wall thickness carbon steel, austenitic steel, and CASS (Cast Austenitic Stainless Steel).
Virtually any array configuration is supported; linear, dual linear, dual matrix, or even custom configurations that our software allows you to easily model.
TPAC’s ready-made inspection software can also be interfaced with advanced analysis platforms like CIVA or ULTIS.
Is your weld inspection a bit “out of the box”?
In that case we have our own Rapid Application Development platform (RAD) that allows us to deliver an inspection software just right for what you need.
