3. Classification
3.1 The welding rods covered by this A5.2 specification utilize a classitication system based on U.S. Customary
Units and arc classified according to the mechanical properties of the weld metal in the as-welded condition, as shown in
Table 1.
3.IM The welding rods covered by this A5.2M specification utilize a classification system based on the International System of Units (SI) and are classified according to the mechanical properties of the weld metal in the as-welded condition, as shown in Table I.
3.2 Welding rods classified under one classification shall not be classified under any other classification in this specification. A welding rod may he classified under both A5.2 and A5.2M providing it meets the requirements of both specifications.
3.3 The welding rods classified under this specification are intended thr oxyfuel gas welding, but that is not to prohibit their use with any other process for which they are found suitable.
4. Acceptance
Acceptance’ of the welding rods shall be in accordance with the provisions of AWS A5.OIM/A5.Ol (ISO 14344 MOD).
5. Certification
By affixing the AWS specification and classification designations to the packaging, or the classification to the product, the manufacturer certifies that the product meets the requirements of this specification.2
6. Rounding Procedure
For the purpo.ce of determining compliance will, the requirements of this standard, the actual fec! values obtained shall he subjected to the rounding rules ofASTM E29 or Rule A in (‘Iai,se 8.3 u/ISO 80000-I (‘the results are the saine,. if the ,neasure’d values are obtained by equipment calibrated in units other luau those of the specified limit, tile’ measured values shall he con verteci to the units of the specif ied limit before rounding. If an average value is to he compared to the specified limit, rounding shall he done only after calculating the average. 4u, observed or calculated value shall he rounded to the nearest 1000 psi (1 kci, J1r tensile strength for A 5.2, and to the nearest JO MPa for tensile strength for A5.2M, and to the nearest unit in the last right—hand place of figures used in expressing the limiting values fOr other quantities. The roumided results shall flit/Ill the requirements fOr the class,! wation under test.
7. Summary of Tests
The tests required for each classification are specified in Table 2. The purpose of these tests is to determine the chemical composition of the welding rod and the mechanical properties of the weld metal. The base metal for the preparation of test samples. the testing procedures to be employed, and the results required are given in Clauses 9 through 11.
9. Weld Test Assembly
9.1 Except for the R45 [RM30] classification, one weld test assembly is required. It is the groove weld for mechanical properties in Figure 1.
9.2 Preparation of the weld test assembly shall be as specified in Figure 1. The base metal for the assembly shall be as required in Table 3 and shall meet the requirements of the appropriate ASTM specification shown there or an equivalent specification. Testing of the assembly shall be as prescribed in Clause 11.
