Overview

EN ISO 24034:2020 - Welding consumables - Solid wire electrodes, solid wires and rods for fusion welding of titanium and titanium alloys - Classification (ISO 24034:2020) specifies how to classify solid wire electrodes, solid wires and rods used for fusion welding of titanium and titanium alloys. The classification is based on chemical composition and is applicable across fusion welding processes (MIG, TIG, plasma, laser and other fusion methods) because the same compositions are used for these processes. EN ISO 24034:2020 is the CEN-endorsed version of ISO 24034:2020 and supersedes EN ISO 24034:2010.

Key topics and requirements

• Scope and purpose: Defines the classification system for titanium welding consumables according to chemical composition rather than by process or mechanical properties.
• Product symbol: The symbol for solid wire electrodes, solid wires and rods is S.
• Chemical composition symbols: Numerical symbols (first two digits indicate the alloy group) and optional additional chemical element symbols identify the composition (see Table 1 and Annex A for explanations).
• Uniform composition across processes: Compositions for MIG consumables are the same as those for TIG, plasma, laser and other fusion welding consumables.
• Chemical analysis: Analysis is to be performed on the product or source stock. Any analytical method may be used; in disputes, established published methods agreed by parties should be referenced.
• Rounding rules: Test values are rounded according to ISO 80000-1:2009 (B.3 Rule A); conversions to units of this document should be done before rounding.
• Retest procedures: Failed tests shall be repeated twice; both retests must meet requirements. Chemical retests can be limited to the elements that failed.
• Mechanical properties: Mechanical properties of all-weld metal or welded joints are explicitly not specified within this classification.
• Delivery and designation: The standard includes technical delivery conditions and rules for product designation (see Clause 10 and Clause 11).

Applications and who uses it

This standard is intended for:

• Manufacturers of welding consumables and filler materials for titanium alloys
• Welding engineers and material specifiers creating procurement documents
• Quality and inspection personnel verifying chemical composition and labelling
• Fabricators in industries using titanium (aerospace, chemical processing, medical devices, marine and high-performance engineering)
• Standards bodies and certification organizations aligning national classifications (see Annex B for corresponding national classifications)

Using EN ISO 24034:2020 helps ensure consistent identification, procurement and traceability of titanium welding consumables based on composition, improving compatibility and quality control in critical welding applications.

ISO 24034:2020(E)
Introduction
This document proposes a classification in order to designate solid wire electrodes, solid wires and
rods in terms of their chemical composition.
There is no unique relationship between the product form (solid wire electrodes, solid wires or rods)
and the welding process used (gas-shielded metal arc welding, tungsten inert gas arc welding, plasma
arc welding or laser beam welding). For this reason, solid wire electrodes, solid wires and rods can be
classified in terms of their chemical composition.
In this document, the symbol of the welding process is not used, because:
a) different joining processes are performed with the same chemical component consumable;
b) the producer is not able to determine the process symbol before shipping.
Also, it should be noted that the mechanical properties of all-weld metal test specimens or welded
joints produced by welding consumables can vary from those obtained in production joints because of
differences in welding procedure and the base-metal alloy. For this reason, the mechanical properties of
all-weld metal or welded joints for titanium-welding consumables are not specified in this classification.

1 Scope
This document specifies requirements for the classification of solid wire electrodes, solid wires and
rods for fusion welding of titanium and titanium alloys. The classification is based on their chemical
composition.
The compositions of solid wire electrodes for metal inert gas (MIG) welding are the same as solid wire
electrodes, solid wires and rods for tungsten inert gas (TIG) arc welding, plasma arc welding, laser
beam welding, and other fusion welding processes.

4 Classification
The classification is divided into two parts:
a) the first part gives a symbol indicating the product to be identified, see 5.1;
b) the second part gives a symbol indicating the chemical composition of the solid wire electrodes,
solid wires and rods, see Table 1.
5 Symbols and requirements
5.1 Symbol for the product
The symbol for the solid wire electrodes, solid wires and rods shall be S.
ISO 24034:2020(E)
5.2 Symbol for the chemical composition
The numerical symbols in Table 1 indicate the chemical composition of a solid wire or rod, determined
under the conditions given in Clause 7. The first two digits indicate the alloy group. See Annex A for an
explanation of the numerical symbols.
The optional additional chemical symbols in Table 1 indicate the chemical composition and include an
indication of the characteristic alloying elements.
6 Mechanical properties
Mechanical properties of all-weld metal or welded joints are not part of this classification.
7 Chemical analysis
Chemical analysis shall be performed on specimens of the product or the stock from which it is made.
See also footnote c to Table 1. Any analytical technique may be used but, in cases of dispute, reference
shall be made to established published methods, agreed between the contracting parties.
8 Rounding procedure
Actual test values obtained shall be subject to ISO 80000-1:2009, B.3, Rule A. If the measured values are
obtained by equipment calibrated in units other than those of this document, the measured values shall
be converted to the units of this document before rounding. If an average value is to be compared to the
requirements of this document, rounding shall be done only after calculating the average. The rounded
results shall fulfil the requirements of the appropriate table for the classification under test.
9 Retests
If any test fails to meet the requirement(s), that test shall be repeated twice. The results of both retests
shall meet the requirement. Specimens for the retest may be taken from the original test assembl
