Elektroda saldimi - Elektrodat me bërthamë tubolare dhe shufra për saldimin me hark të metaleve me mbrojtje me gaz dhe pa mbrojtje me gaz të çeliqeve të pa oksidueshëm dhe çeliqeve me qëndrueshmëri ndaj nxehtësisë – Klasifikimi. – Amendament 1 (ISO 17633:2017/Amd 1:2021).

Welding consumables - Tubular cored electrodes and rods for gas shielded and non-gas shielded metal arc welding of stainless and heat-resisting steels - Classification (ISO 17633:2025)

Scope

ISO 17633:2017 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 17633:2017 is a combined standard providing for classification utilizing a system based upon nominal composition or utilizing a system based upon alloy type.
a) Clauses, subclauses, and tables which carry the suffix letter "A" are applicable only to products classified using the system based upon nominal composition.
b) Clauses, subclauses, and tables which carry the suffix letter "B" are applicable only to products classified using the system based upon alloy type.
c) Clauses, subclauses, and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all products classified in accordance with this document.
ISO 17633:2017 does not use pulsed current for determining the product classification.
