NM01RCBLOCK

The Curtis RC (AWS Resolution) Block, constructed from 1018 carbon steel, is a precision-engineered calibration standard designed specifically for evaluating the resolution capabilities of ultrasonic testing (UT) systems, particularly angle beam transducers. This block adheres to the stringent requirements of the American Welding Society (AWS) standards, ensuring accurate and reliable performance in weld inspection and other critical applications.

Key Features and Benefits:

• AWS Compliance:

  • Manufactured in strict accordance with AWS standards, notably AWS D1.1 (Structural Welding Code—Steel), guaranteeing compatibility and consistency with industry-recognized testing protocols.  

• 1018 Carbon Steel Construction:

  • Utilizes 1018 carbon steel, a material known for its uniform ultrasonic transmission properties and consistent acoustic behavior. This ensures reliable and repeatable calibration results.

• Precision-Machined Through-Holes:

  • Features precisely drilled through-holes at specific angles (typically 45°, 60°, and 70°), simulating realistic weld defects. These holes serve as reference reflectors for assessing the resolution of the UT system.  

• Resolution Evaluation:

  • Designed to assess the ability of an ultrasonic testing system to distinguish between closely spaced reflectors. This is crucial for accurately detecting and characterizing defects in welds and other materials.

• Calibration Standard:

  • Serves as a reliable calibration standard for angle beam transducers, enabling UT technicians to verify and optimize their equipment's performance.  

• Curtis Quality:

  • Manufactured by Curtis Industries, Inc., a trusted provider of calibration blocks and reference standards, ensuring high quality and precision.

• Dimensional Accuracy:

  • Common dimensions are 6.000" x 3.000" x 1.000" (152.4 mm x 76.2 mm x 25.4 mm) and these blocks are manufactured to tight tolerances.

Applications:

• Calibration of angle beam transducers in ultrasonic testing.

• Evaluation of UT system resolution for weld inspection.

• Verification of equipment performance in accordance with AWS standards.

• Quality control in manufacturing and fabrication.

• Training and certification of ultrasonic testing personnel.
