3. Classification 3.1 This new A5.36/A5.36M specification utilizes two classification systems. The first of these is a “fixed classification” system which has been carried over to this specification from AWS A5.20/A5.20M or from AWS A5.18/A5.18M. as applicable, for the classification of those carbon steel flux cored or metal cored electrodes which, with the specific mechanical properties specified for them in A5.20/A5.20M or A5. 18/A5.18M, have gained wide acceptance for single pass and multiple pass applications. See Table 1 for a list of those classifications and the applicable requirements. The sccond classification system is an “open classification” system w hich is introduced with this specification for the classi- fication of carbon and low-alloy steel flux cored electrodes and carbon and low -alloy steel metal cored clectrodes. This open classification system provides the flexibility to classify an expanded number of electrode types with a variety of shielding gases (if any) to different requirements for strength, impact properties, weld metal composition, and condition of heat treatment.
The flux cored and metal cored electrodes covered by the A5.36 specil cation uiili,e a classification system based UOfl U.S. Customary Units. Electrodes covered by the A536M specification utilize a system based upon the International System of Unils (SI). Under these specifications, flux cored and metal cored electrodes can he classified for multiple pass welding or for single pass welding. The groove weld test assembly ‘how n in Figure 2 is used for the classification of multiple pass electrodes. The two-run butt weld lest assembly shown in Figure 3 is used for the classification of single pass electrodes.
3.1.1 The flux cored electrodes classified utilizing the used classification” system arc classified for multiple pass welding based upon the following:
(I) The as-welded mechanical properties of the weld metal obtained with a particular shiekling gas. if any. as spedficd in Table I.
(2) The positions of welding for which the electrode is suitable, as indicated in Noic b of Table I.
(3) Certain usability characteristics of the electrode (including the presence or absence of a shielding gas). Refer to
Note h of Table I and to Table 4.
3.1.2 The flux cored and metal cored electrodes classified utilizing the ‘open classification” system are classified based upon the followmg:
(I) The mechanical properties of the weld metal, as specified in Table 2. Table 3. and Table 7.
(2) The positions of welding for which the electrodes arc suitable.
(3) Certain usability characteristics of the electrode (Including the presence or absence of a shielding gas). as sped- lied in Table 4.
(4) The nominal composition of the shielding gas used, if any, as specified in Table 5.
(5) The condition of posiwekl heat treatment, if any. as specified in Table 8.
(6) Chemical composition of the weld metal as specified in Table 6.AWS A5.36-A5.36M pdf download.
