GOST 14771-76 PDF

Full title and description

GOST 14771-76 — Gas-shielded arc welding. Welded joints. Main types, design elements and dimensions. The standard specifies the principal types, structural elements and dimensional requirements for welded joints produced by arc welding in shielding gas for steels and for iron‑nickel and nickel‑base alloys.

Abstract

This interstate (GOST) standard defines standard forms and constructive elements of welded joints used in gas‑shielded arc welding, gives conventional designations and nominal dimensions depending on material thickness and welding method, and provides rules for selecting preparations and weld geometry for butt, corner, T‑, lap and other common joint types. It does not set types/dimensions for steel pipelines covered by GOST 16037‑80.

General information

• Status: In force (published 1976; later reprints and amendments). The limitation of effectiveness was lifted and the standard remains used with its recorded amendments.
• Publication date: Approved July 28, 1976; date of introduction (effective date) July 1, 1977.
• Publisher: Standards Publishing House / Gosstandart (Interstate official edition; English version also issued).
• ICS / categories: 25.160.40 (Welds and welding).
• Edition / version: Original designation GOST 14771-76 with Amendments No. 1, 2 and 3 (amendments recorded in 1982, 1986 and 1989); published/issued in reprints (including a 2006 edition that collects those amendments).
• Number of pages: Approx. 30–35 pages depending on the edition (page count varies by scanned/reprinted editions and language versions).

Scope

The standard applies to welded joints executed by arc welding in shielding gas (inert and active shielding gases) for steels and alloys on iron‑nickel and nickel bases. It standardizes the main joint types (butt, corner, T, lap, etc.), design elements (preparation shapes, bevels, root face, root gap, weld reinforcement and throat dimensions) and nominal dimensional ranges by base‑metal thickness and welding method. It explicitly excludes welded joints of steel pipelines covered by GOST 16037‑80.

Key topics and requirements

• Classification of welded joint types for gas‑shielded arc welding (butt, corner, T, lap, fillet, etc.).
• Definition of constructive elements: edge preparation forms (single/ double bevels, curvilinear bevels, chamfers), root face, root gap, weld throat and reinforcement.
• Nominal dimensional tables and limits for joint elements depending on base metal thickness and welding method (manual, mechanized, submerged/chain‑type distinctions where applicable).
• Conventional alphanumeric designations for joint types and weld execution variants used on drawings and specifications. (xn--24-8kcixc2c1c.xn--p1ai)
• Application notes and exclusions (for example, pipeline joints specified by other standards).

Typical use and users

Used by welding engineers, structural and mechanical designers, manufacturing engineers, shop foremen, welding procedure writers, quality/control inspectors and standards specialists when specifying joint preparations and weld geometry for components and assemblies welded by arc processes in shielding gas. Also used in technical education and for creating drawing instructions and welding procedure specifications.

FAQ

Q: What is this standard?

A: GOST 14771-76 is an interstate standard that establishes the main types, constructive elements and nominal dimensions for welded joints produced by arc welding in shielding gases.

Q: What does it cover?

A: It covers classification of joint types (butt, corner, T, lap, etc.), shapes of prepared edges, dimensional tables for root gaps, bevels, weld throat and reinforcement, and conventional designations used on drawings. It applies to steels and iron‑nickel or nickel‑base alloys welded in shielding gas and excludes pipeline joint rules covered by a separate standard.

Q: Who typically uses it?

A: Welding engineers, fabricators, mechanical and structural designers, welding procedure authors, inspectors and educators use it when specifying joint preparations and interpreting drawing callouts for gas‑shielded arc welding.

Q: Is it current or superseded?

A: The standard was approved in 1976 and introduced in 1977 and has recorded amendments (Nos. 1–3). Official sources indicate the standard remains in use (reprinted editions exist and limitations of effectiveness were lifted). For project‑critical work always check the latest national/interstate registry or the issuing body for any subsequent replacements or newer national standards.

Q: Is it part of a series?

A: It belongs to the family of welding and welded‑joints standards in the GOST system (standards covering manual arc welding, pipe joints, weld symbols, welding materials, etc.) and is cross‑referenced with several related GOSTs.

Q: What are the key keywords?

A: Key terms include arc welding, shielding gas, welded joints, joint types, bevel, root gap, weld size, and welding designations.
