1.3.3 Other Processes. Other welding processes may he used when approved by the Engineer. In such case, the Engineer shall specify any additional qualification requirements necessary to assure satisfactory joints for the intended service.
1.4 Weld Metal Requirements
1.4.1 Matching Filler Metals. When using the indicated weld process, the filler metals listed in Table 1.2 provide a weld joint with strengths matching that of the base metal.
1.4.2 Other Base Metal—Filler Metal Combinations. Base metal—filler metal combinations other than those described in 1.4.1 shall be permitted when evaluated and approved by the Engineer. When base metals of dissimilar strengths are welded, the filler metal tensile strength shall be equal to or greater than that of the lowest tensile strength base metal.
1.4.3 Manufacturer’s Certification. When requested by the Engineer, the contractor shall furnish an electrode manufacturer’s certification stating that the electrode will meet the requirements of the classification.
1.4.4 Electrodes for Shielded Metal Arc Welding (SMAW)
1.4.4.1 AWS Specification. Electrodes for SMAW shall conform to the requirements of the latest edition of AWS A5. I /A5. I M. Specification for Carbon Steel Electrodes for Shielded Metcil Arc Welding. or to the requirements of AWS A5.5/A5.5M. Specification for Low-Alloy Steel Electrodes for Shielded Metal Arc 11Velding.
1.4.4.2 Low-Hydrogen Electrode Control. This control shall be for sheet steel that is welded to a primary structural member which is thicker than 1/4 in [6.4 mm], placing the jurisdiction of this control as specified in AWS Dl.l.
1.4.5 Submerged Arc Welding (SAW)
1.4.5.1 AWS Specification. The bare electrodes and fluxes used in combination for SAW shall conform to the requirements of the latest edition of AWS A5. 1 7/A5. 1 7M. Speciflcation for Carbon Steel Electrodes and Fluxes for Submerged Arc Welding, or to the requirements of the latest edition of AWS A5.23/A5.23M, Specification for Low-A llov Steel Electrodes and Fluxes for Submerged Arc Welding.
1.4.5.2 Flux. Flux used for submerged arc welding shall he dry and free of contamination from dirt, mill scale, oils, or other foreign material. All flux shall he purchased in packages that can he stored, under normal conditions, for at least six months without such storage affecting its welding characteristics or weld properties. Flux from damaged packages shall he discarded or shall he dried at a minimum temperature of 250°F [1 20°Cj for one hour before use. Flux shall he 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 he discarded. Flux that has been wet shall not be used.
1.4.6 Gas Metal Arc Velding, Flux Cored Arc Welding (FCAW), and Gas Tungsten Arc Welding (GTAW) Filler Metals
1.4.6.1 AWS Specification. The filler metals and shielding for GMAW, FCAW, or GTAW shall conform to the requirements of the latest edition of AWS A5. 1 8/A5. 1 8M, Specification Jr 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, or AWS A5 . 29/A5 . 29M, Specification for Low-A llov Steel Electrodes for Flux Cored Arc Welding, as applicable.
1.4.6.2 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.
1.5 Weld Types
1.5.1 Square-Groove Welds in Butt Joints. This type of weld is restricted to the welding of sheet steel to sheet steel in all positions of welding.
1.5.2 Fillet Welds. This type of weld 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.
