Processing and characterization of submerged arc welding (SAW) flux [PDF]
Submerged arc welding (SAW) is a process that melts and joins metals by heating them with an arc established between a consumable wire electrode and the metals, with the arc being shielded by a molten slag and granular flux.SAW flux is an important welding consumable material which may tend to welding defect such as inclusions if not properly selected.

Performance of a welding flux is decided by the physical and chemical properties of its constituents. The flux selected should show a good welding behavior and the required weld bead geometry. The mechanical properties of a joint are not only decided by its composition but these also depends on bead geometry, dimensions and physico-chemical properties ...

The origin of acicular ferrite in the weld metal of submerged arc weldments on high strength steels is very complex and depends upon the chemical composition for the steel base plate and filler wire, the composition of the flux used during welding and the cooling rate of the weld metal during the transformation of the undercooled metastable austenite ...

Recycling of submerged arc welding slag for sustainability
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 ...

Concern about the environment and the scarcity of natural resources has led to the search for more sustainable alternatives that minimize the environmental impact of all segments of society. Solid waste recycling has been presented as a good alternative to reduce the impacts generated by the disorderly use of raw materials and the reduction of disposal

The modeling of heat affected zone (HAZ) in submerged arc welding (SAW) surfacing steel element
In the work the bimodal heat source model in the description of the temperature field is presented. The electric arc was treated physically as one heat source, whose heat was divided: part of the heat is transferred by the direct impact of the electric arc, but another part of the heat is transferred to the weld by the melted material of the electrode.
