3. Classification The welding electrodes and rods covered by A5.22/A5.22M utilize a classification system that is independent of U.S. Customary Units and the International System of Units (SI). Classifications for the flux cored electrodes and rods indi- cate the chemical composition of the undiluted weld metal, as specified in Table 1FC, the position of welding, and the external shielding gas required (for those classifications for which one is required), as specified in Table 2. Classifica- tions for the metal cored electrodes indicate the chemical composition of the undiluted weld metal only, as specified in Table 1MC. Electrodes and rods may not be classified under more than one classification in this specification, except on the basis of carbon content and shielding gas used provided they meet all the requirements of those classifications as specified in Table IFC and Table 1MC. More than one classification based upon any element other than carbon is not permitted. Table 3 lists a number of examples of possible dual classification. The flux cored electrodes and rods classified under this specification are intended for flux cored arc welding and for root pass welding with the gas tungsten arc process, but this does not prohibit their use with any other process for which they are found suitable. The metal cored electrodes and rods classified under this specification are intended for gas metal arc welding, gas tungsten arc welding, plasma arc welding, and submerged arc welding, but this does not prohibit their use with any other process for which they are found suitable.
9.2 Preparation of each weld test assembly shall be as prescribed in 9.3, 9.4, and 9.5. Base metal for each assembly shall conform to the following or an equivalent:
9.2.1 For the chemical analysis pad. the base metal to he used shall he carbon steel, low-alloy steel, or stainless steel of 0.25% carbon maximum for all classifications of electrodes and rods except for classifications with up to 0.04% carbon maximum. For chemical analysis of these low carbon classifications, the base metal shall be steel of 0.03% carbon maximum. Other steels having a carbon content of 0.25% maximum may be used with the further restrictions in 9.3.2 and 10.1.2.
9.2.2 For all-weld-metal tension and radiographic tests, the steel to be used shall be of a matching type or either of the following:
(1) For E4XXTX-X and E4XXTO-3 classifications—ASTM A 240, Types 410. 430A, or 430B
(2) For all other classifications—ASTM A 240, Types 304 or 304L
Optionally, the steel may conform to one of the following specifications or their equivalents, provided two buttering layers of the filler metal, as shown in Figure 2, are deposited in stringer beads using electrodes of the same classification, or an equivalent classification of AWS A5.4/A5.4M, as that being classified:
ASTM A 36, ASTM A 285. or ASTM A 515
9.2.3 For the bend test, if required. and for the fillet weld test, if required, the steel to be used shall be of a matching type or either of the following:
(1) For E4XXTX-X classifications—ASTM A 240, Types 410. 430A, or 430B
(2) For all other electrode/rod classifications—ASTM A 240. Types 304 or 304L.AWS A5.22 – A5.22M  pdf download.
