Ultrasonic Rail Welds Flaw Detector
The Ultrasonic Rail Welds Flaw Detector is an integrated rail flaw and welding beam detector. Welds are the weakest points of a continuous welded rail: they are made in the field, they cool unevenly and defects
Ultrasonic Rail Welds Flaw Detector
The Ultrasonic Rail Welds Flaw Detector is an integrated rail flaw and welding beam detector. Welds are the weakest points of a continuous welded rail: they are made in the field, they cool unevenly and defects inside the weld cannot be seen from the surface. This instrument is built for crews that need to check welds and the rail either side of them with the same ultrasonic technology Ultra Instrument applies across its detection vehicles and trolleys. Detailed specifications for this model are supplied on request, so ask our engineers for the datasheet before you specify it.
- Checks rail welds and the adjacent rail with one ultrasonic instrument
- Combines rail flaw detection and welding beam inspection in one unit
- Built by the same engineering team behind the UR18-D and GT6600 vehicles
- Backed by pre-sales, in-sales and after-sales technical support
- Suited to crews that already run Ultra Instrument detection equipment
Specifications for this model are supplied on request. Email our engineers for the datasheet.
Problems It Solves
- Defects inside a rail weld cannot be found by visual or hammer inspection
- Welds are made in the field where conditions are harder to control
- Carrying two separate instruments for rail and weld checks slows a crew down
- Weld failures develop into rail breaks if they are not found early
Who It Is For
Railway bureaus responsible for weld quality on continuous welded rail
Track maintenance contractors carrying out flash butt and thermite welding
Metro operators verifying welds made during possession windows
Industrial railway operators without an in-house NDT laboratory
Application Scenarios
- Checking field welds after rail replacement or repair
- Weld inspection on continuous welded main line track
- Weld checks on metro and light rail during night maintenance windows
- Weld verification on private industrial and port lines
Technical Features
- Integrated rail flaw and welding beam detection in a single instrument
- Ultrasonic testing technology developed in house by Ultra Instrument engineers
- Part of a product range built around non-destructive wheel probe technology

How It Is Operated
Tell us the rail profile and weld type you inspect
Our engineers confirm the configuration and send the datasheet
The instrument is supplied with commissioning and operator training
Suspect indications are confirmed by manual verification before any rail action
Quality Control
- Suspected defect positions are confirmed by manual verification before any rail action
- Ultra Instrument passed the rail flaw detection equipment inspection and review of Xi'an Railway Bureau in 2016
Customization Options
- Configuration matched to the rail profile and weld type in service
- On-site commissioning and operator training arranged with the order
How It Compares With Other Options
| UR18-D dual rail vehicle | The vehicle inspects long stretches of plain rail at 15 km/h, while this instrument is aimed at welds and the rail around them |
|---|---|
| CK2108 handheld universal flaw detector | The CK2108 is a general purpose ultrasonic detector, this unit is dedicated to rail flaw and welding beam inspection |
| Visual and hammer inspection of welds | Manual checks cannot see inside the weld and depend on the operator, ultrasonic testing does not |
Use Guide
- Confirm the weld type and rail profile before configuring the instrument
- Inspect the weld together with the rail either side of it
- Mark every suspect indication for manual verification
- Ask our engineers for the operating procedure supplied with the instrument

What does this detector inspect?
It is an integrated rail flaw and welding beam detector, so it is used on rail welds and on the rail either side of the weld.
Where can I get the full specifications?
Detailed specifications for this model are supplied on request. Email [email protected] with your rail profile and weld type and our engineers will send the datasheet.
Why do welds need separate attention?
Welds are made in the field, cool unevenly and can contain defects that are invisible from the surface, so they are checked with ultrasonic testing rather than by eye.
Does it replace a rail flaw detection vehicle?
No. A vehicle such as the UR18-D covers long stretches of plain rail at speed. This instrument is aimed at welds and the rail immediately around them.
Do you provide training?
Yes. Ultra Instrument provides pre-sales, in-sales and after-sales technical service, on-site engineer training and construction team support.
How do I request a quotation?
Email [email protected] with the rail profile, weld type and the number of welds you inspect each year and our engineers will reply with a configuration.
