1.6.4.2 Low-Hydrogen Elctrode Control. This control shall be for sheet steel that is welded to a primary structural member which is thicker than 1/4 in [6 mm], placing the jurisdiction of this control as specified in AWS D1.1/ D1.1M. 1.6.4.3 Nonlow-hydrogen Electrodes. Nonlow- hydrogen electrodes may be used in a qualified WPS for arc spot. arc seam. and arc plug welds of sheet metal in the flat position to primary structural members thicker than %4 in [6 mm]. as limited by Annex A Table A.1 Note 1. 1.6.5 Submerged Arc Welding (SAW) 1.6.5.1 AWS Specification. The bare electrodes and fluxes used in combination for SAW shall conform to the requirements of the latest edition of AWS A5. 17/A5.17M, Specification for Carbon Steel Electrodes and Fluxes for Submerged Are Welding, or to the requirements of the latest edition of AWS A5.23/A5.23M, Specification for Low-Alloy Steel Electrodes and Fluxes for Submerged Arc Welding. 1.6.5.2 Flux. Flux used for submerged are welding shall be dry and free of contamination from dirt, mill scale, oils, or other foreign material. All flux shall be purchased in packages that can be stored, under normal conditions, for at least six months without such storage affecting its welding characteristics or weld properties. Flux from damaged packages shall be discarded or shall be dried at a minimum temperature of 250°F [120°C] for one hour before use. Flux shall be placed in the dispensing system immediately upon the opening of a package, or if used from an opened package, the top 1 in [25 mm] shall be discarded. Flux that has been wet shall not be used. 1.6.6 Gas Metal Arc Welding (GMAW, Flux Cored Arc Welding (FCAW), and Gas Tungsten Arc Welding (GTAW) Filler Metals
1.6.6.1 AWS Specification. The filler metals and shielding for GMAW, FCAW, or GTAW shall conform to the requirements of the latest edition of AWS A5.18/A5.18M, Specification for Carbon Steel Electrodes and Rods for Gas Metal Arc Welding, or AWS A5.28/A5.28M, Specification for Low-Alloy Steel Electrodes and Rods for Gas Shielded Arc Welding, AWS A5.20/A5.20M, Specification for Carbon Steel Electrodes for Flux Cored Arc Welding, AWS A5.29/ A5.29M, Specification for Low-Alloy Steel Electrodes for Flux Cored Arc Welding, or AWS A5.36/A5.36M. Specification for Carbon and Low-Alloy Steel Flux Cored Electrodes for Flux Cored Arc Welding and Metal Cored Electrodes for Metal Arc Welding as applicable. 1.6.6.2 Shielding Media. A gas or gas mixture used for shielding in GMAW, FCAW when required, or GTAW, shall meet the requirements of AWS A5.32/ A5.32M, Specification for Welding Shielding Gases. When requested by the Engineer, the gas manufacturer shall furnish certification that the gas or gas mixture meets the requirements of AWS A5.32/A5.32M. 1.7 Weld Types 1.2.1 Square-Groove Welds in Butt Joints. These types of welds are restricted to the welding of sheet steel to sheet steel in all positions of welding. 1.7.2 Fillet Welds. These types of welds may be used in all positions of welding involving sheet steel to sheet steel or a sheet steel to a supporting structural member.AWS D1.3/D1.3M pdf download.
