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
Formed when one element is perpendicular to the other, often used in bridge or machine frames.
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 gost 526480 english pdf better
For corner and T-joints, the leg size is established during design but generally should not exceed 1.2 times the thickness of the thinner part. Understanding Designations
For international projects or English-speaking teams, obtaining an official translation is vital for accuracy. Several platforms provide the full text and technical drawings: The standard specifically governs manual arc welding and
Applied when the edge of one part meets the surface of another at an angle, common in supports and frames.
Typically ranges from 1mm to 4mm. In construction/installation conditions, this can be increased to 4mm for materials thicker than 16mm. On technical blueprints, symbols like , T2 , or У3 are used
Used to connect parts edge-to-edge in the same plane. They are ideal for thick materials where high tensile strength is required.
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
