Ultrasonic Testing
Ultrasonic Testing (UT) uses high-frequency sound waves to detect internal flaws and measure material thickness with precision.
Overview
Ultrasonic Testing (UT) transmits high-frequency sound waves through a material; reflections from internal discontinuities or the back wall are timed and measured to locate flaws and gauge thickness. It is one of the most versatile NDT methods, capable of finding sub-surface cracks, laminations, inclusions and corrosion that surface methods cannot detect.
NDT Australia deploys both conventional pulse-echo UT and phased array (PAUT) where complex geometry or detailed flaw sizing is required. Results are recorded digitally, giving you traceable evidence of weld quality and remaining wall thickness.
Applications
Ultrasonic Testing is applied across a wide range of assets and industries, including:
- Volumetric weld inspection on structural and pressure equipment
- Wall-thickness surveys on tanks, vessels and pipelines
- Lamination checks on plate and structural steel
- Sizing and monitoring of known defects over time
Standards & Compliance
Our inspections are performed and reported to the applicable Australian and international standards:
- AS 2207 — Non-destructive testing of welds by ultrasonics
- ISO 16810 — Ultrasonic testing general principles
Why Choose NDT Australia
- Detects deep internal and sub-surface defects
- Accurate thickness measurement to fractions of a millimetre
- Single-sided access is often sufficient
- Immediate, digitally recorded results
