Solutions for the ultrasonic inspection of long steel products

Waygate Technologies' line of Krautkrämer ROWA™ Ux industrial automated UT systems are the most compact and simplistic solution for the full-body inspection of bars, billets and wire stock made from (stainless) steel alloys, aluminum, brass, and titanium on the market.

The system is designed for the highest quality requirements and meets all common ultrasonic inspection standards such as ISO 18563, AMS2154 Class AA, NADCAP as well as the industrial standards of the automotive and aviation industries. The compact dimensions of the mechanics enable for the most cost- effective integration into existing or new inspection lines. The optionally available reference standard manipulator “RSM” also enables a fully automatic, 100% reproducible sensitivity adjustment without any operator influence

Ultrasonic inspection of bar and wire starts here

Non-destructive testing (NDT) of bar stock is subject to constantly increasing demands concerning the quality of the test. This applies to bright precision steel and special bar quality (SBQ) levels as well as to hot-rolled black steel bar and wire, which often are used as a semi-finished product for cold-drawn bars.

Until the mid-2000s, eddy current inspection only was still sufficient to meet the quality requirements of the automotive industry. Today, non-destructive ultrasonic testing has become a standard method for most material qualities.

Phased-array test systems require significantly less maintenance, have a higher level of availability and, at the same time, place lower demands on the personnel than conventional ultrasonic test systems, since all settings of previously prepared data sets are made fully automatically and are reproducible.



  • Ease of operation: The fully refreshed software is in accordance with the latest usability standards
  • Simply follow the workflow process (setup - calibrate - inspect – analyze) to accelerate your setups and make them more consistent
  • Low cost of ownership: Krautkrämer ROWA™ Ux features a simplified test mechanics with phased array probes mounted to just a solid stainless-steel body
  • With no moving parts or complex swivel mechanisms submerged in contaminated water, maintenance is significantly reduced to maximise uptime
  • Probes can be changed by a single operator without the need for a crane or special tools, so your plant's material flow is not affected

  • Performance capability: The latest generation modular design includes fast optical data transmission and ensures the system‘s robustness
  • The integrated diagnostic features and remote connectivity ease the day to day use of the equipment.

  • Aerospace industry
Compact Design

The Krautkrämer ROWA™ Ux Series is the most compact full-body inspection solution for inspecting metal bars available in the market. Due to the compact dimensions of the mechanics, the ROWA™ Ux system can be seamlessly integrated into an existing inspection line or installed offline in a rolling mill manufacturing process for quality assurance purposes.

Workflow-Based User Interface

The Krautkrämer ROWA™ Ux software has been fully revised in accordance with the latest usability standards. Operators must simply follow the workflow that takes them through the whole inspection process from beginning to end:

Setup – Calibrate – Inspect – Analyze.


Powerful New Modular USIPxs Platform

Krautkrämer ROWA™ Ux 's state-of-the-art USIP|xs electronics platform processes the gathered inspection data at very high speeds for fast on-line inspection with an exceptional probability of detection.

Its modular design with digital optic signal transmission between boxes facilitates robustness, easy maintenance, and enables the fast change of broken electronic parts. Because of this integrated box design, less spare parts are needed.

Improved Performance
Increased Testing Speeds

With newly implemented capabilities, the Krautkrämer ROWA™ Ux achieves up to 30% higher testing speeds.

Maximized Calibration Repeatability

Thanks to the automatic calibration and system checks with the reference standard manipulator RSM, you can achieve maximum calibration repeatability without user intervention.

Meets Industry Standards

The Krautkrämer ROWA™ Ux meets ISO 18563, AMS2154 class AA, NADCAP, and all major automotive and aerospace industry standards to meet the certification requirements of your end customers and guarantees your investment is future proof. 

Easy Maintenance

The Krautkrämer ROWA™ Ux has compact test mechanics with non-moving parts, no bearings, and no rotating seals due to Phased Array Technology. This results in overall system robustness, short changeover times, and minimum commissioning time.

The ultrasonic coupling is realized by a rotating water (ROWA) jacket, generated by tangentially flowing coupling water. It constantly expels dirt and prevents air bubbles from forming in the water. The bars are then fed into the test chamber one-by-one on linear tracks by a guiding and transport device. A lifting/shifting table is required for the installation of the test mechanism within the guiding and transport line.
