GOST 5264-80 PDF

Full title and description

GOST 5264-80 — "Manual arc welding. Welded connections. Main types, structural elements and dimensions." The standard establishes the principal types of welded joints produced by manual arc welding, the constructive elements of those joints, dimensional requirements and conventional designation of seams on drawings.

Abstract

This standard defines shapes, edge preparations, seam cross‑section elements, dimensional limits (gaps, seam width, convexity/concavity, leg sizes for fillet welds), symbols and designation rules used on technical drawings for manual arc welded joints of steels and certain nickel‑based alloys. It also includes rules for intermittent seams, allowable displacements of edges before welding and guidance for joints of unequal thickness.

General information

• Status: Active / in force (introduced in the USSR system and retained as an interstate technical standard; restrictions on use were later removed).
• Publication date: Original approval 1980 (designation -80); officially introduced 1 July 1981.
• Publisher: State standards authority of the USSR / Interstate standards system (Gosstandart / EASC) — issued under the USSR State Committee on Standards.
• ICS / categories: Welding and allied processes (ICS classification ~ 25.160.40, group B05).
• Edition / version: GOST 5264-80 (1980); later consolidated/cleaned editions and amendments noted (amendments recorded in 1989 and editorial updates subsequently).
• Number of pages: Approximately 35 pages (standard document length as published in common collections).

Scope

Applies to welded connections produced by manual electric arc welding (MMA/MIG/MAG variants as applicable for manual methods) of steel and some alloyed materials, excluding specific pipeline welding rules covered by separate standards. The standard covers principal joint types (butt, fillet/tee, lap, corner), edge preparations, recommended dimensions and limits for weld geometry, and the graphical and alphanumeric designation of seams on engineering drawings.

Key topics and requirements

• Main joint types and standard alphanumeric designations for welds used on drawings (butt, T, corner, lap, fillet, plug/slot where applicable).
• Specified structural elements of seams: root face, groove angle, gap (b), seam width (e), convexity/concavity limits (g) and permissible deviations.
• Dimensional tables and limits by material thickness (maximum gap and permissible thickness differences for welding without bevel).
• Rules for intermittent seams (chain/chess patterns), required pitch/length relationships and maximum spacing relative to element thickness.
• Permitted displacements of edges before welding depending on part thickness and guidance for beveling when thickness differences exceed limits.
• Symbols for welding method codes (e.g., manual arc variants) and guidance on indicating assembly/installation seams versus final welds on drawings.

Typical use and users

Used by mechanical and structural designers, welding engineers, detailers and draughtsmen preparing fabrication drawings, welding procedure developers, quality and inspection personnel, and vocational trainers to ensure consistent joint geometry, fit‑up practice and drawing notation for manual arc welding in industrial fabrication. Welding inspectors and certification bodies also reference it when assessing conformity of welded structures to established dimensional and graphical requirements.

Related standards

The standard is commonly used together with other GOSTs that address complementary aspects of welding and drawing notation, for example standards on spot welds, welded connections in shielding gases, pipe welding rules and graphical welding symbols (examples frequently referenced alongside GOST 5264‑80 include GOST 8713‑79, GOST 14771‑76, GOST 14806‑80, GOST 16037‑80, GOST 16038‑80 and drawing/symbol rules such as GOST 2.312‑72).

FAQ

Q: What is this standard?

A: GOST 5264‑80 is a Soviet/interstate standard that sets out the main types, structural elements and dimensional requirements for welded joints produced by manual arc welding; it also defines the conventional designations used on engineering drawings.

Q: What does it cover?

A: It covers joint types (butt, fillet/T, corner, lap), edge preparations and bevels, dimensional limits for seams (gaps, seam width, leg size, convexity/concavity), allowable fit‑up tolerances, rules for intermittent seams and the symbolic/alphanumeric notation of seams on drawings.

Q: Who typically uses it?

A: Designers, welders, welding engineers, drawing offices, quality/inspection staff and trainers in metal fabrication and structural manufacturing who need consistent joint geometry and standard drawing notation for manual arc welding.

Q: Is it current or superseded?

A: The original GOST 5264‑80 was approved in the USSR system (designation -80) and introduced 1 July 1981; later amendments and editorial revisions were issued (noted amendments in 1989 and subsequent consolidations). National/interstate authorities have maintained the standard in force or referenced its provisions in successor collections; historical records indicate that time limits on its validity were later lifted and the standard remains a commonly cited reference for manual‑arc welded joint geometry.

Q: Is it part of a series?

A: It belongs to the family of GOST documents governing welding practices and welded‑joint documentation; related GOSTs cover spot welding, welding in shielding gases, pipe welding and drawing/symbol conventions. Together these standards form the normative framework for welded connection design and drawing in the GOST system.

Q: What are the key keywords?

A: Manual arc welding, welded connections, butt weld, fillet weld, seam dimensions, bevel, welding symbols, fit‑up tolerance, intermittent seam, GOST 5264‑80.
