GOST 33976-2016 PDF

Full title and description

GOST 33976-2016 — "Welded joints in steel structures of railway rolling stock. Requirements for design, production and quality control." The standard establishes technical requirements and acceptance criteria for the design, execution and quality control of welded joints and welded assemblies used in steel structures of railway rolling stock.

Abstract

Specifies requirements for selection of weld types, welding procedure documentation, weld quality categories, fabrication and inspection methods (visual, dimensional, mechanical and non‑destructive testing), and rules for quality control and certification of welding operations applied to railway vehicle steel structures. It includes provisions for climatic versions in accordance with GOST 15150 and lists exclusions such as repair of cast parts and certain hazardous‑equipment welds.

Scope

Applies to the design, execution and quality control of welded joints and welded assemblies in steel structures of railway rolling stock (including climatic variants per GOST 15150). The standard does not apply to repair of defects in cast parts, welding of equipment for hazardous production facilities or certain tank/aircraft reservoir welds, nor to routine repair of rolling stock outside the specified manufacturing/quality control regime.

Key topics and requirements

• Classification of welded joints and allowable weld types for rolling‑stock structural elements.
• Requirements for welding procedure specifications (WPS), welder/operator qualification and welding coordination.
• Weld quality categories and acceptance criteria (visual, dimensional, mechanical testing, NDT—ultrasonic, radiographic, magnetic particle, penetrant where applicable).
• Rules for joint preparation, root penetration (full/partial), layered welding, and weld thickness considerations.
• Factory quality control, inspection plans, documentation and certification traceability for welded assemblies.
• References to related GOST/ISO standards for welding terms, NDT methods and test procedures.

Typical use and users

Used by rolling‑stock designers and structural engineers, welding engineers and technologists, production managers in rail‑vehicle manufacturing, quality assurance and inspection personnel, certification bodies and regulatory authorities overseeing railway equipment safety and conformity. It is applied in both new construction and pre‑acceptance production inspection workflows.

Related standards

Cross‑references and related documents commonly cited include GOST 15150 (climatic versions), GOST R ISO 857‑1 (welding vocabulary), GOST 5264 (manual arc welding joint types), and various ISO standards on welding and NDT (for example ISO/EN methods referenced in later revisions). The standard is also referenced by several rolling‑stock technical specifications and vehicle general‑spec standards.
