This International Standard specifies requirements for classification of tubular flux and metal cored electrodes and rods, based on the all-weld metal chemical composition, the type of electrode core, shielding gas, welding position and the all-weld metal mechanical properties, in the as welded or heat treated conditions, for gas shielded and non-gas shielded metal arc welding of stainless and heat-resisting steels.
This International Standard is a combined standard providing for classification utilizing a system based upon classification according to nominal composition, or utilizing a system based upon classification according to alloy type.
1) Paragraphs and tables which carry the label “classification according to nominal composition” are applicable only to products classified to that system.
2) Paragraphs and tables which carry the label “classification according to alloy type” are applicable only to products classified to that system.
3) Paragraphs and tables which carry neither label are applicable to products classified according to either or both systems.
It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of pulsed current, but for the purposes of this International Standard, pulsed current is not permitted for determining the electrode classification.
