Conventional NDT Methods
Visual Testing (VT)
The foundational NDT method, involving the systematic observation and evaluation of component surfaces.
Liquid Penetrant Testing (PT)
A widely used method to locate surface-breaking defects in non-porous materials.
Magnetic Particle Testing (MT)
Detects surface and near-surface flaws in ferromagnetic materials by applying a magnetic field.
Radiographic Testing (RT)
Utilizes X-rays or gamma rays to view the internal structure of components, revealing hidden defects.
Direct Visual Inspection
Close-up examination of surfaces using the naked eye or magnifying tools.
Remote Visual Inspection
Using borescopes, fiberscopes, and drones to inspect inaccessible areas.
Weld Visual Inspection
Assessment of weld quality, alignment, and surface characteristics against codes.
Surface Condition & Coating
Evaluation of surface preparation, coating thickness, and integrity.
Visible Dye Penetrant Testing
Uses a colored dye to reveal surface-breaking flaws under normal lighting conditions.
Fluorescent Dye Penetrant Testing
A highly sensitive method using fluorescent dye that glows under UV light to show defects.
Solvent Removable Method
Ideal for spot checks and on-site inspections where water washing is not practical.
Water Washable Method
A common and efficient method for inspecting large quantities of parts with smooth surfaces.
Wet Fluorescent (WFMT)
The most sensitive magnetic particle technique, used for detecting very fine cracks.
Dry Powder Magnetic Testing
Effective for rough surfaces and for inspections at elevated temperatures.
Yoke Method (Portable)
Uses a portable electromagnetic yoke to inspect welds and components in the field.
Bench Method (Stationary)
High-volume inspection of smaller parts using a stationary magnetic testing unit.
X-Ray Radiography
Ideal for inspecting thinner materials and composites with high sensitivity.
Gamma Ray Radiography
A portable method used for inspecting thick-walled materials, pipelines, and dense components.
Computed Radiography (CR)
A digital imaging process that replaces traditional film, offering wider latitude and digital storage.
Digital Radiography (DR)
Provides real-time radiographic images, allowing for immediate analysis and faster inspections.
Advanced NDT Methods
Ultrasonic Testing (UT)
Uses high-frequency sound waves to detect internal flaws, measure thickness, and identify corrosion.
Eddy Current Testing (ET)
An electromagnetic technique used for detecting surface flaws and sorting materials by conductivity.
Acoustic Emission (AE)
A passive NDT method that "listens" for transient elastic waves to detect active damage in a structure.
Infrared & Thermal Testing (IRT)
Detects thermal anomalies in electrical, mechanical, and structural systems to identify potential failures.
Conventional UT
Standard ultrasonic techniques for flaw detection and thickness measurement.
Phased Array (PAUT)
Advanced UT that uses multiple elements to create steerable beams for complex geometries.
Time-of-Flight Diffraction (TOFD)
A highly sensitive method for rapid weld inspection and accurate flaw sizing.
Automated UT (AUT)
Uses robotic scanners for fast, repeatable, and recordable inspections of pipelines and vessels.
Surface Flaw Detection
Rapidly detects surface-breaking cracks and flaws in conductive materials.
Tube & Pipe Inspection
Used for inspecting heat exchanger tubes and pipes for corrosion, pitting, and cracks.
Material & Conductivity Sorting
Sorts metals and alloys based on their electrical conductivity and permeability.
Weld Inspection
Provides rapid surface inspection of welds for cracks and other discontinuities.
Structural Health Monitoring (SHM)
Continuous, real-time monitoring of structures like bridges and vessels for active crack growth.
Leak Detection
Detects and locates leaks in pressurized systems, pipelines, and storage tanks.
Pressure Vessel Testing
Monitors the structural integrity of pressure vessels during hydrotests.
Composite Material Inspection
Detects damage such as delamination and fiber breakage in composite structures.
Electrical Systems Inspection
Identifies overheating components in electrical panels, switches, and connections.
Building Envelope & Roof Scans
Detects heat loss and moisture intrusion in building structures and roofing systems.
Mechanical Systems Monitoring
Monitors rotating equipment like motors and bearings for abnormal heat signatures.
Process & Refractory Monitoring
Inspects the condition of refractory linings in furnaces, kilns, and reactors.
Project Spotlight
Phased Array UT for Critical Weld Inspection in a Power Plant
A power generation facility required a rapid and highly accurate inspection of critical welds in a new steam turbine system during a scheduled shutdown, with minimal downtime.
BQCIS utilized Phased Array Ultrasonic Testing (PAUT), an advanced UT technique that provides a detailed, real-time visual of weld integrity, allowing for faster and more reliable flaw detection than conventional methods.
The inspection was completed 40% faster than with conventional radiography, identifying all defects with a high degree of precision. The client was able to complete repairs and restart operations ahead of schedule, preventing significant production losses.
