GOST 11534-75 PDF

Full title and description

GOST 11534-75 — "Manual arc welding. Welded joints at acute and obtuse angles. Main types, design elements and dimensions." The standard defines main types, constructive elements and dimensional requirements for welded angle joints produced by manual arc welding with a consumable electrode, for carbon and low-alloy steels (thicknesses up to 60 mm), and includes Amendment No. 1.

Abstract

This interstate (GOST) standard specifies standardised joint types, edge preparations, weld shapes and dimensional tables for angle (acute and obtuse) welded connections made by manual arc welding. It is intended to ensure interchangeability and reproducible quality of welded joints in structural and mechanical assemblies where parts are joined at angles. The standard excludes certain deep-penetration pipeline welds and gives mandatory dimensional/constructive rules for the covered range.

General information

• Status: Listed in authoritative registries as in-force / implemented (the document record notes the original expiration limit was removed in 1991); some commercial lists also report it among standards scheduled or noted for withdrawal in later compilations—see FAQ for details.
• Publication date: Approved 12 December 1975; date of introduction (entry into force) 01 January 1977.
• Publisher: Approved by the State Committee for Standards (Gosstandart) of the Council of Ministers of the USSR (interstate standard).
• ICS / categories: Welding and welded joints — ICS 25.160 (Welding, brazing and soldering); relevant subgroup for welded joints and welds (ICS 25.160.40).
• Edition / version: Original GOST 11534-75 with Amendment No. 1 (amendment approved May 1991; publication editions include a 2001 reprint incorporating the amendment).
• Number of pages: Approx. 23 pages in standard PDF/printed copies (commercial catalogues list 23–24 pages depending on edition).

Scope

GOST 11534-75 applies to welded angle (corner and butt at angles) connections produced by manual arc welding with a melting electrode in all spatial positions for carbon and low-alloy steels where the weld metal thickness is up to 60 mm inclusive. It sets the standardised main types of joints, detailed constructive elements (edge preparation, backing, weld profile) and dimensional tables for those joint types. The standard does not set types/dimensions for pipeline joints and welds produced by welding with deep penetration.

Key topics and requirements

• Standardised classification of angle welded joints (acute and obtuse angles) and their conventional designations.
• Recommended forms of edge preparation and design elements (single- and double-sided preparations, backing practices and removable/permanent backing where applicable).
• Dimensional tables with limit and recommended sizes for weld leg length, throat, bevels, root openings and angles for different base metal thickness ranges.
• Rules for selecting joint form and weld type depending on part thickness, angle of assembly and required weld penetration/profile.
• Mandatory application note: requirements of the standard are binding where referenced or adopted in design/specifications (original text states requirements are mandatory).

Typical use and users

This standard is used by design offices, welding engineers, fabrication shops, quality and inspection personnel, and technical libraries concerned with structural steelwork, machinery manufacture and welded assemblies where angle joints are common (frames, brackets, trusses, machinery housings). It is referenced in construction and fabrication specifications, welding procedure documentation and teaching materials for weld design.

Related standards

Commonly referenced or related documents include earlier and parallel GOSTs on welded joints and welding processes (for example, the replaced edition GOST 11534-65, and other GOSTs covering welded joints produced by different welding methods, e.g. GOST 14771-76, GOST 14776-79, and standards on weld design and welding practice). National and international welding standards on joint types and symbols (ISO/ICS series 25.160) are also relevant when harmonising requirements.

FAQ

Q: What is this standard?

A: GOST 11534-75 is an interstate (GOST) standard titled "Manual arc welding. Welded joints at acute and obtuse angles. Main types, design elements and dimensions." It provides standard types and dimensional rules for angle welded joints produced by manual arc welding.

Q: What does it cover?

A: It covers classification, edge preparations, constructive elements and dimensioning tables for angle welds (acute and obtuse) made by manual arc welding with a consumable electrode for carbon and low-alloy steels (weld metal thicknesses up to 60 mm). It explicitly excludes certain pipeline deep-penetration welds.

Q: Who typically uses it?

A: Welding engineers, fabricators, design engineers, quality inspectors and standards librarians working with welded steel structures and mechanical assemblies where angle joints are used. It is referenced in welding procedure specifications and technical designs.

Q: Is it current or superseded?

A: Official registry records indicate the standard was approved in 1975 and introduced 01 January 1977; a notice in the document record states the original expiration limit was removed by Gosstandart in 1991, and editions incorporating Amendment No. 1 have been published (e.g., a 2001 reprint). Commercial and catalogue listings generally show it as available. However, some compilations and commercial lists have included GOST 11534-75 in lists of standards noted for withdrawal or that were removed from certain consolidated catalogues around 2018. If you need to know the standard's legal status for a specific regulatory or contractual purpose, check the up-to-date national standards registry or a commercial standards service for the destination country.

Q: Is it part of a series?

A: It is part of the broader family of GOST standards addressing welding and welded joints (the ICS 25.160 family). Related GOSTs address other joint types, welding processes and testing methods; GOST 11534-75 replaced the earlier 1965 version (GOST 11534-65) and is commonly used alongside complementary GOSTs for welding practice.

Q: What are the key keywords?

A: Manual arc welding; angle (acute/obtuse) joints; weld dimensions; edge preparation; welded joint types; carbon steel; low-alloy steel; GOST.
