BS EN ISO 24034:2020 pdf download.Welding consumables — Solid wire electrodes, solid wires and rods for fusion welding of titanium and titanium alloys — 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 Sd;
h) 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.
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 assembly or sample or from one or two new test assemblies. For chemical analysis, retests need only be for those specific elements that failed to meet the requirement. If the results of one or both retests fail to meet the requirement, the material under test shall be considered as not meeting the requirements of this document for that classification. In the event that during preparation, or after completion of any test, it is clearly determined that prescribed or proper procedures were not followed in preparing the weld test assembly or sample(s) or test specimen(s), or in conducting the tests, the test shall be considered invalid. This determination is made without regard to whether the test was actually completed, or whether the test results met, or failed to meet, the requirements. That test shall be repeated, following proper prescribed procedures. In this case, the requirement for doubling the number of test specimens does not apply.BS EN ISO 24034 pdf download.
