Product Overview

The 7 Step Wedge Ultrasonic Calibration Block manufactured by NDE FLAW TECH INDIA is a precision-engineered reference standard developed for Ultrasonic Testing (UT) applications. It is designed to support reliable calibration, equipment verification, procedure qualification, technician training and repeatable inspection performance before production inspection is performed.

The product incorporates carefully controlled reference features such as side-drilled holes, flat-bottom holes, steps, radii, notches or reference reflectors, allowing inspectors to evaluate range calibration, sensitivity setting, resolution, beam angle, DAC/AVG/DGS response and thickness verification under controlled and repeatable conditions. As a manufacturing-focused NDT product, it helps inspection teams establish a dependable baseline response, compare instruments or probes, validate inspection procedures, and maintain consistency between laboratory, shop-floor and field inspection activities.

NDE FLAW TECH INDIA manufactures this product using controlled material selection, precision CNC machining, EDM / reference defect manufacturing where applicable, dimensional verification and final quality inspection. Standard configurations can be supplied for routine applications, while customized versions can be manufactured according to customer drawings, OEM procedures, project specifications or international inspection requirements.

The 7 Step Wedge Ultrasonic Calibration Block is suitable for inspection companies, OEM manufacturers, maintenance teams, quality laboratories, training institutes and industrial end users requiring durable, traceable and repeatable NDT reference standards. Each product can be supplied with identification marking, serial number traceability and supporting documentation to help customers maintain calibration records and quality system compliance.
