GOST R 55724-2013 PDF

Full title and description

GOST R 55724-2013 — Non-destructive testing. Welded joints. Ultrasonic methods. The standard specifies ultrasonic inspection methods, scanning schemes and procedures, equipment and transducer types, and rules for detecting and characterizing discontinuities in welded joints of metallic products.

Abstract

This national Russian standard (GOST R 55724-2013) establishes requirements and recommended procedures for ultrasonic nondestructive testing (UT) of welded joints (butt, corner, lap and T‑joints) made by common welding processes. It covers test methods (pulse-echo, echo-shadow, diffraction, Delta and related techniques), scanning schemes, specimen/test-piece preparation considerations, personnel qualification and documentation necessary for performing and recording ultrasonic weld inspections.

Scope

The standard applies to ultrasonic inspection of welded connections in metallic products to detect and evaluate discontinuities such as cracks, lack of penetration, pores, and non‑metallic or metallic inclusions. It defines applicable weld types (butt, corner, lap, T‑joints with full root penetration), applicable welding processes (arc, electroslag, gas, electron beam, laser, pressure welding and combinations), recommended scanning schemes (direct, single‑reflection, double‑reflection, angled‑beam), and procedures for locating, sizing and classifying indications in welds.

Key topics and requirements

• Common ultrasonic methods and modes used for weld inspection (pulse‑echo, echo‑shadow, echo‑mirrored, diffraction, Delta technique) and guidance on their application.
• Scanning schemes and beam paths for different joint geometries (straight/oblique probes, direct/reflective schemes, longitudinal/transverse scanning, oscillating beam options).
• Transducer selection and use (direct and angled transducers, surface and head waves for near‑surface defects).
• Acceptance and defect characterization rules (types of discontinuities to detect, detection zones, sizing and evaluation principles).
• Requirements for technical documentation: defined controlled joints, testability requirements, test methods, equipment parameters, calibration and setup, sequence of operations, result registration and reporting.
• Personnel qualification and responsibilities for performing ultrasonic testing and interpreting results (qualification/competency requirements referenced).

Typical use and users

Used by NDT technicians and inspectors, welding engineers, quality assurance and control personnel, inspection laboratories, fabricators of pressure equipment, pipelines, bridges and structural steelwork, and regulatory bodies overseeing welded construction and manufacturing where ultrasonic weld inspection is required.

Related standards

GOST R 55724-2013 is listed alongside other Russian and harmonized standards for nondestructive testing and ultrasonic examination of welds (examples include GOST R ISO 17640 series and other GOST R/ISO documents on ultrasonic testing and personnel qualification). National practice references and related GOSTs on NDT procedures, calibration and reporting are commonly used together with this standard.
