GOST 27265-87 PDF

Full title and description

GOST 27265-87 — "Welding wire of titanium and titanium alloys. Technical conditions." The standard specifies technical requirements, grades, dimensions, mechanical and chemical requirements, testing, marking and packaging for filler (welding) wire made of titanium and titanium alloys used as welding consumables and filler material in fabrication and repair.

Abstract

This national standard establishes requirements for production and acceptance of titanium and titanium-alloy welding wire (filler wire). It covers designation of grades, permissible chemical compositions, mechanical properties, sizes (diameters), surface quality, sampling and test methods, marking, packing and delivery conditions intended to ensure interchangeability and reliable welding performance in aerospace, medical, chemical and general engineering applications.

General information

• Status: Active / in-force as published (originally approved by the USSR State Committee for Standards).
• Publication date: Approved 31 March 1987 (Resolution No. 1114); bibliographic/publication records commonly show 1987/1989 as the entry dates (GOST 27265-87).
• Publisher: Approved by the State Committee for Standards of the USSR (Gosstandart); subsequently maintained within national/regional standards systems that handle Soviet-era GOST standards.
• ICS / categories: Materials and metallurgy; welding consumables and procedures (ICS: welding and related technologies — commonly under the 77 series for welding). (Category indicative.)
• Edition / version: Original designation GOST 27265-87 (first issue introduced 1987); carries later amendments noted in bibliographic sources.
• Number of pages: Approximately 19 pages (bibliographic listings indicate ~19 pp for the standard text).

Scope

The standard applies to welding filler wire manufactured from commercially pure titanium and various titanium alloys intended for use as filler material in fusion welding. It defines which grades/brands of titanium wire are covered, the required chemical composition limits and mechanical properties, acceptable tolerances for wire diameter and straightness, testing and inspection procedures, and requirements for marking, packing and transport to ensure the material is suitable for its intended welding purposes.

Key topics and requirements

• Designation of filler-wire grades and permissible chemical compositions (limits for Ti, O, N, H, Fe and alloying elements as applicable).
• Mechanical property requirements (tensile strength, elongation) and acceptance criteria for supplied reels/coils.
• Dimensional tolerances for wire diameters, surface condition (cleanliness, absence of defects) and permissible deviations.
• Sampling, testing and inspection methods (chemical analysis, tensile tests, microstructure or non-destructive checks where required).
• Marking, labeling, packaging and delivery requirements to preserve wire quality and traceability during storage and shipment.
• Reference and normative cross-references to other GOSTs and technical documents used for sampling, testing and materials (listed in normative references).

Typical use and users

Manufacturers and suppliers of welding consumables, fabricators and repair shops that perform fusion welding of titanium and titanium-alloy components, and end-users in aerospace, chemical processing, medical device manufacturing, shipbuilding and specialty engineering use this standard to specify and procure filler wire that meets required chemical and mechanical characteristics. Commercial suppliers and metal distributors list GOST 27265-87 when offering titanium welding wire grades (e.g., VT1‑00, VT6sv, VT20 variants) intended for industrial welding.

Related standards

GOST 27265-87 contains normative references to multiple related GOST documents used for testing and material specification, for example ГОСТ 3282-74, ГОСТ 3560-73, ГОСТ 5009-82, ГОСТ 6456-82, ГОСТ 6507-90 and several others cited in the normative references list of the standard. These referenced standards cover methods of analysis, sampling, tensile testing, packaging and related procedures.

FAQ

Q: What is this standard?

A: GOST 27265-87 is the Soviet / Russian national standard that sets technical conditions for welding (filler) wire made from titanium and titanium alloys — covering grades, chemical and mechanical requirements, testing, marking and packaging.

Q: What does it cover?

A: It covers production and acceptance requirements for titanium welding wire: grade designation, allowable chemical composition ranges, mechanical properties, dimensional tolerances, sampling and test methods, marking and packing rules required for supply and use as a welding filler.

Q: Who typically uses it?

A: Producers of welding wire, purchasing engineers and quality departments in aerospace, medical device manufacturers, chemical and process industry fabricators, metal distributors and welding workshops use the standard to specify and verify filler wire for titanium welding. Commercial suppliers reference it when offering titanium welding wire to industry.

Q: Is it current or superseded?

A: Bibliographic sources list GOST 27265-87 as the original standard approved in 1987 and in commercial catalogues it is still referenced as the applicable specification for titanium welding wire; the standard record also indicates later amendments. Users should verify the current legal/regulatory status and any regional successors or updated normative documents with their national standards body before procurement.

Q: Is it part of a series?

A: The standard is part of the family of GOST documents governing metallic materials, welding consumables and test methods; it cites and depends on a number of other GOSTs for sampling, analysis and mechanical testing procedures.

Q: What are the key keywords?

A: Key keywords include titanium welding wire, filler wire, titanium alloys, welding consumables, GOST 27265-87, wire grades (VT1‑00, VT6sv, VT20), chemical composition, mechanical properties, and packing/marking.
