ISO 14341:2010 pdf free download – Welding consumables一Wire electrodes and weld deposits for gas shielded metal arc welding of non alloy and fine grain steels – Classification.
Chemical analysis shall be performed on specimens of the wire. Any analytical technique may be used, but in case of dispute, reference shall be made to established published methods.
In the case of chemical elements which do not change during production, chemical analysis of the wire may be substituted by an analysis of product in process or raw material or a report of the ladle chemical analysis of a raw material.
6A Classification by yield strength and 6B Classification by tensile strength
The results of the chemical analysis shall fulfil the The results of the chemical analysis shall fulfil the requirements given in Table 3A for the classification requirements given in Table 3B for the classification under test.
7 Rounding procedure
For purposes of determining compliance with the requirements of this International Standard, the actual test values obtained shall be subjected to ISO 80000-1:2009, Clause B.3, Rule A. If the measured values are obtained by equipment calibrated in units other than those of this International Standard, the measured values shall be converted to the units of this International Standard before rounding. If an arithmetic average value is to be compared to the requirements of this International Standard, rounding shall be done only after calculating the arithmetic average. If the test method cited in Clause 2 contains instructions for rounding that conflict with the instructions of this International Standard, the rounding requirements of the test method shall apply. The rounded results shall fulfil the requirements of the appropriate table for the classification under test.
8 Retests
If any test fails to meet the requirement, that test shall be repeated twice. The results of both retests shall meetthe requirements. Specimens for the retest may be taken from the original test assembly or from a new test assembly. For chemical analysis, retest need only be for those specific elements that failed to meet their test 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 specification 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 test specimen(s), or in conducting the tests, the test shall be considered invalid, 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.
9 Technical delivery conditions
Technical delivery conditions shall meet the requirements in ISO 544 and ISO 14344.
A weld deposit produced by gas shielded metal arc welding having a minimum tensile strength of
490 MPa (49) and a minimum average impact energy of 47 J at 0 °C (0) in the as-welded condition
under carbon dioxide (C1) using the wire S11 is designated as follows:
ISO 14341-B-G 49A 0U C1 S11
A wire electrode complying with the chemical requirement of S11 in Table 3B is designated as
follows.
