3 Terms and Definitions

The terms and definitions defined in GB/T 12604.1, GB/T 20737 and GB/T 32563, as well as the following terms and definitions, apply to this document.

4 General Requirements

4.1 Unless otherwise agreed in the agreement between the supplier and the buyer, the inspection shall be carried out during the main production processes of round steel (rolling, heat treatment, hot and cold working and straightening, etc.). Proceed after completion.

4.2 The surface of the round steel to be inspected should be flat and smooth, free from loose oxide scale, oil stains and other contaminants that may affect the inspection.

4.3 Detection can be performed using contact technology, partial or full immersion technology. Contact technology can use water, oil, grease or paste as coupling agents; immersion technology...

The technology can use water or oil as a coupling agent. Corrosion inhibitors, wetting agents, and defoamers can be added to the water to prevent the round steel from rusting and to protect the round steel from phase control.

Bubbles are generated on the surface of the array probe.

4.4 The testing environment should avoid strong light, strong electromagnetic fields, strong vibration, corrosive gases, heavy dust, and other factors that may affect the stable operation of the ultrasonic testing instrument.

Factors that can be reliably observed by testing personnel.

4.5 Testing personnel shall meet the requirements specified in GB/T 9445 or equivalent standards. In cases involving third-party testing, the testing shall be conducted by both the supplier and the buyer.

The agreement was reached through negotiation.

4.6 The scanning tracks of the phased array probe should continuously and uniformly cover the surface of the round steel, and the scanning width between adjacent tracks should be at least 10% of the equivalent beam width.

The degree of overlap. See Appendix A for the measurement of the equivalent beam width.
