is a cornerstone technical standard that establishes the fundamental types, design elements, and dimensions for welded joints produced through manual arc welding . Introduced on July 1, 1981, this standard remains a critical reference for engineers and welders working with steels, as well as nickel-based and iron-nickel alloys. Scope and Applicability
Permissible displacement ranges from 0.5mm for thin materials to up to 4mm for parts exceeding 100mm in thickness.
Formed when one element is perpendicular to the other, often used in bridge or machine frames. gost 526480 english pdf better
Includes specifications for V-shaped, U-shaped, and K-shaped beveling.
Applied when the edge of one part meets the surface of another at an angle, common in supports and frames. is a cornerstone technical standard that establishes the
For international projects or English-speaking teams, obtaining an official translation is vital for accuracy. Several platforms provide the full text and technical drawings:
Used to connect parts edge-to-edge in the same plane. They are ideal for thick materials where high tensile strength is required. Formed when one element is perpendicular to the
The standard specifically governs manual arc welding and applies to various metal structures. However, it is important to note that GOST 5264-80 to steel pipeline joints, which are instead covered by GOST 16037-80 . Core Types of Welded Joints
GOST 5264-80 classifies welded joints into four primary categories, each designated by a specific letter for identification on technical drawings:
On technical blueprints, symbols like , T2 , or У3 are used. The number following the letter indicates a specific execution variant (e.g., single-sided vs. double-sided weld or specific bevel type). For instance, C1 refers to a single-sided butt joint without edge preparation for thin sheets. Where to Find GOST 5264-80 English PDF
