ISO 17633 specifies requirements for classification of tubular flux and metal cored electrodes and rods, based on the all-weld metal chemical composition, the type of 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 is a combined standard providing classification utilizing a system based upon nominal composition or utilizing a system based upon alloy type.
Note: ISO 17633 does not use pulsed current for determining the product classification.
ISO 17633 on welding consumables is applicable to
Standardization in welding procedures is becoming more and more important due to the increasing quality and performance standards.ISO 17633 provides you with a better classification system for tubular cored electrodes and rods for welding stainless and heat-resistant steels.
By implementing ISO 17633, manufacturers can understand that there are two somewhat different approaches in the global market to classify a given tubular stainless steel welding consumable, and one or both can be employed to meet a specific market requirement. Compliance with the standards informs customers that the quality and performance of the products are at the best in industry.
