This Standard specifies the requirements for shielding gases and the tolerances on the nominal value of constituent gases in mixtures. This Standard applies, but is not limited, to the following processes:
(a)Gas tungsten arc welding(GTAW)
(b)Gas metal arc welding(GMAW)
(c) Flux cored are welding(FCAW)
(d)Plasma arc welding(PAW)
NOTES:
For further information on shielding gases for GTAW and GMA W refer to Appendix A.
For information on safety in the use of shielding gases, see Appendix B.
3 CLASSIFICATION
The shielding gases covered by this Standard shall be classified using a designation system (independent of metric or imperial units )in accordance with Clause 4
NOTE: Gases classified under one classification are not classified under any other classification in this Standard.
Individual gases shall meet or exceed the requirements of Table 1.
5 QUALITY CONTROL
5.1 Summary of tests
Compositional analysis of the shielding gas shall be required for the classification of a product under this Standard. Tests required for each single gas shall be as specified in Table 3.
NOTE: The purpose of these tests is to determine the purity and maximum moisture content of the shielding gas.
