ČSN EN ISO 3581   (055100) Svařovací materiály - Obalené elektrody pro ruční obloukové svařování korozivzdorných a žáruvzdorných ocelí - Klasifikace

Anotace textu normy ČSN EN ISO 3581   (055100)

This document specifies requirements for classification of covered electrodes, based on the all-weld metal chemical composition, the type of electrode covering and other electrode properties, and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for manual metal arc welding of stainless and heat-resisting steels.

This document 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.

a) Paragraphs and tables which carry the label ´classification according to nominal composition-A´ or ´ISO 3581-A´ are applicable only to products classified to that system.

b) Paragraphs and tables which carry the label ´classification according to alloy type-B´ or ´ISO 3581-B´ are applicable only to products classified to that system.

c) Paragraphs and tables which carry neither label are applicable to products classified according to either or both systems.

Annex B gives information on considerations on weld metal ferrite content.
