ISO 17633:2010

ISO 17633:2010 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.
ISO 17633:2010 is a combined standard providing for classification utilizing a system based upon nominal composition or utilizing a system based upon alloy type.
It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of pulsed current, but ISO 17633:2010 does not use pulsed current for determining the electrode classification.
