Covered electrodes for manual arc welding of creep-resisting steels — Code of symbols for identification

Establishes a code for the identification of covered electrodes by means of symbols. The codification is divided into four parts: The first part symbolizes the type of product, the second part is a symbol for the chemical composition of the deposited weld metal, the third part is a symbol for the type of coating, and the fourth part is a symbol for the welding characteristics of the electrode.
