Development of submerged arc welding flux from rice straw ash

Materials and Manufacturing Processes, 2023
At present, a large amount of rice straw ash is being dumped as waste creating soil and water pollution. The manufacturing of welding fluxes requires minerals which are mined out from the earth’s crust creating environmental ill effects.

Optimization of hardness of weld in submerged arc welding

Materials Today: Proceedings, 2020
Abstract If a high quality of welding joint in thick metal is required, submerged arc welding process is preferably used. There are several welding input process parameters which influence the quality of the weld. Some important input process parameters in the case of submerged arc welding process are welding current, welding voltage, wire feed and ...

Submerged-arc vertical welding

Welding International, 1987
Abstract There is a growing demand for semi-automatic welding of vertical weld seams under building site conditions. The possiblity of submerged-arc welding with single and multilayer build-up of the weld has been tested in small scale trials. Some details about equipment and technology from published data are included.

Waste to wealth: Recycling of steel slag as flux for the submerged arc welding process and its effect on mechanical and metallurgical properties of welds

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2022
A novel technology has been developed to recycle steel slag as a flux for the submerged arc welding process. The chemical, mechanical, and metallurgical properties of welds produced using recycled slag have been evaluated and compared with that of fresh ...

Thermal model of submerged arc welding

Materials Science and Technology, 1992
AbstractA model for calculating the temperature field in submerged arc welding is presented. The algorithm is based on the method of elementary balances. Melting of the electrode rod and melting of the parent material followed by solidification of the pool of molten metal are considered. The calculated temperature evolution curves are compared with the

Sensitivity analysis of submerged arc welding process parameters [PDF]

Journal of Materials Processing Technology, 2008
Selection of process parameters has great influence on the quality of a welded connection. Mathematical modelling can be utilized in the optimization and control procedure of parameters. Rather than the well-known effects of main process parameters, this study focuses on the sensitivity analysis of parameters and fine tuning requirements of the ...

Improved Titanium Transfer in Submerged Arc Welding of Carbon Steel through Aluminum Addition

Mineral Processing and Extractive Metallurgy Review, 2021
In Submerged Arc Welding of carbon steel, element transfer of Titanium from the molten flux to the weld metal is limited to small quantities as reported in literature, 310 ppm maximum. This limitation is due to the high oxygen potential prevailing at the

Metal transfer in submerged arc welding

Journal of Materials Processing Technology, 2017
Abstract The movement of molten metal at the wire end in submerged arc welding (SAW) was filmed by a high-speed video camera through a preset tunnel, the welding electric signal was acquired simultaneously. A physical modeling experiment was carried out to simulate the metal transfer in SAW. Welding electric signal shows that the stability of welding
