Ultrasonic testing or inspection is a method of Non Destructive Testing that is increasingly popular.
It is widely used for testing composite structures and components. This is due to the fact that it enables highly accurate results for finding the location and size of defects such as cracks and voids.
The method involves putting the object to be inspected in contact with an ultrasonic transducer connected to a diagnostic machine. This causes beams of mechanical waves (vibrations) of short wavelength and high frequency to be transmitted through the object. Then the waves are measured and compared with existing standards.
With UT you will be able to measure the thickness and internal structure of the object and find hidden flaws.
This method is most commonly used for the following purposes:
- Thickness checking to check for laminations in parent material and to detect extremely minute flaws within welded joints.
- Thickness checking – example would be to detect internal corrosion on service pipelines.
- Lamination checking – example would be parent materials are often checked prior to welding in case there are any defects present.
- Welded join testing – example would be when welded joints are in a butt weld or T-butt weld configuration, UT is carried out to examine the parent metal / heat affected zone and weld metal for any volumeric defects.
Benefits of Ultrasonic Testing
There are a variety of benefits of using ultrasonic testing with Code a Weld, including the following:
- By enforcing quality control, you are demonstrating high standards in terms of quality and safety.
- Deeper penetration makes it superior to other NDT methods.
- When using the pulse-echo technique you only need access from one side.
- Little set-up time is required before carrying out the examination.
- You can receive instant results.
- We have three decades of experience in NDT.
- Compliance with legal and government regulations.
- UT can be used for thickness measurement, fault finding and other reasons.
- We guarantee quick turnaround times without having to compromise on accuracy.
