Similar to MIG welding, SAW involves formation of an arc between a continuouslyfed bare wire electrode and the workpiece. The process uses a flux to generate protective gases and slag, and to add alloying elements to the weld pool. A shielding gas is not required. Prior to welding, a thin layer of flux powder is placed on the workpiece surface.

1 Introduction. Submerged arc welding (SAW) process uses heat generated by an electric arc established between a bare consumable electrode wire and the workpiece. Since in this process, welding arc and the weld pool both are completely submerged under mound of granular fusible and molten flux; therefore, it is called submerged arc welding.

Methodology used for recycling the slag has been presented graphically in Fig. 30 kg of slag was collected from an Indian industrial unit engaged in the manufacturing of pressure vessels, boilers, digesters and chemical process vessels, free of cost. Fig. 2 (a) shows the slag as collected from the industry. The slag was crushed and sieved to make its grains size distribution ...

Thanks for your info Tommyjoking, but the slag came from Submerged Arc Welding as you know it generates a huge amount of slag. In history, we normally crushed the slag to consider as Recovered, mixed it with Flux (25% Recovery and 75% ) and used it in production, but we stop that practice due to Customer requirements and related quality issues.

Steel slag is one of the most common waste products from the steelmaking industry. Conventional methods of slag disposal can cause negative impacts on humans and the environment. In this paper, the process of steel and steel slag production, physical and chemical properties, and potential options of slag recycling were reviewed. Since steel is mainly produced through an electric arc furnace ...

Welding fluxes that have suffered from serious water and moisture contamination, or have been exposed to the atmosphere over long periods of time cannot be restored in their original condition and should be discarded. 5. Recycling Non consumed flux collected from the weld shall be cleaned from slag, metal and/or other contamination.

As the welding progresses along the length, the molten weld metal covered by the liquid flux cools and solidifies to create a weld bead with a protective slag above it. The flux is a nonconductor of electricity in its cold condition, and hence the arc is normally struck by touching the electrode with the workpiece or using a highfrequency unit.

The American Welding Society (AWS) defines slag as "a nonmetallic byproduct of the mutualdissolution of flux with nonmetallic impurities in welding and brazing processes.". In short, it is the hardened layer left on the top of weld made during fluxcored welding (FCAW). It is also present in shielded metal arc welding (SMAW), submerged arc ...

Flux formulations are specified to target chemical and physicochemical parameters. Chemical parameters set flux element transfer behaviours and weld metal oxygen contents. Physicochemical parameters such as slag viscosity, surface tension and melting range are targeted to ensure an acceptable weld bead profile and surface appearance. Slag detachability is an important physicochemical ...

SAW flux plays several roles during the welding process. It provides arc enhancers, produces shielding gas, protects the weld from the atmosphere, assists in bead shape, deoxidizes the weld puddle, and some even add alloy to the weld metal. Flux is manufactured by one of three methods known as fused, agglomerated or bonded, and mechanically mixed.

ABSTRACT The objective of this paper is to investigate the utilization of Submerged Arc Welding (SAW) slag as a fresh flux for sustainability. Certain alloying elements were added to the crushed slag to adjust the resultant composition of the weld metal as per American Welding Society (AWS) and operational characteristics such as arc stability. Here, four distinct controllable variables ...

In past decades, SAW slag materials were found to be dumped in yards, land filling activities which possess ecofriendly issues and land pollution. Attempts were also made to use slag in cement mortar and masonry applications of civil engineering. However the actual recycling of slag in welding industries has not gained momentum.
