IS 15977 : 2013 : Classification and Acceptance Tests for Bare Solid Wire Electrodes and Wire Flux Combination for Submerged Arc Welding of Structrual Steel - Specification

(Superseding IS 7280 : 1974 and IS 3613 : 1974)

Reaffirmed 2024

1 SCOPE

1.1 This standard contains two sections. Section 1 deals with the classification of bare solid wire electrodes and wire-flux combination for submerged arc welding of structural steel. Section 2 deals with the acceptance tests for wire-flux combination for submerged arc welding of structural steel.

1.2 This standard specifies the requirements of solid filler wire, classifications of wire-flux combinations and all-weld metal properties of each combination in as welded conditions for submerged arc welding of various structural steels (300-450 N/mm2 yield strength and 400-700 N/mm2 ultimate tensile strength).

1.3 Any filler wire classified under one particular classification shall not be classified under any other classification of this standard.

1.4 Fluxes may be classified in combination with different wire under more than one classification.
