Corrosion of Furnace Tubes By Residual Welding Slag [PDF]
Corrosion, 1960 Describes case history of severe and rapid corrosion of hydrogen reforming furnace tubes during high temperature operation. Attack was caused by presence of residual welding slag, sulfur and reducing conditions. Welding slag played a primary role in this corrosion. Explains repairs and modifications taken to correct the corrosion problem.

Slag-metal equilibrium during submerged arc welding
Metallurgical Transactions B, 1981A thermodynamic model of the equilibria existing between the slag and the weld metal during submerged arc welding is presented. As formulated, the model applies only to fused neutral fluxes containing less than 20 pct CaF2, however some results indicate that the model may be useful in more general cases as well.

Recycling of slag to act as a flux in submerged arc welding
Resources, Conservation and Recycling, 2009Abstract The slag generated during submerged arc welding is thrown away as a waste. Non-biodegradable nature poses problems of storage, disposal, soil pollution and also needs landfill space for dumping. It cannot be used as a filling material in building construction or elsewhere being glassy and brittle material.

Influence of Slag-Flux Mixture on the Properties of Welded Joints
Advanced Materials Research, 2014<p>Submerged arc welding (SAW) is one of the most versatile welding processes. All steel grades, from non- to high alloyed, including Ni-based alloys, can be welded with a combination of various techniques. The process became common worldwide for these properties, and shows a high degree of growth in countries with significant heavy industry.

Influence of weld slag aggregate in high-performance concrete
Proceedings of the Institution of Civil Engineers - Waste and Resource Management, 2016Rapid increase in urban infrastructural developments in developing countries such as India leads to the need for natural resources such as river sand. The accessibility of the natural resources is diminishing rapidly. At present, other sources of fine aggregates are in great demand.

Production of new welding fluxes based on silicomanganese slag
Welding International, 2018The properties of a welding flux based on the silicomanganese slag are investigated. The flux is produced using the slag formed in the production of silicomanganese with different ratios of the sla...

Behaviour and influence of slag islands in ferritic stainless steel welds
Welding in the World, 2017The nature and detailed behaviour of slag islands in ferritic stainless steel welds have been analysed via weld pool video imaging, welding parameter monitoring, scanning electron microscopy, and in situ optical emission spectroscopy. The aim of the investigation was to understand how changes in weldability in 31 commercial very low-sulphur steels of ...

Anti-Corrosion Methods and Materials, 1996
Points out that the pitting resistance of welds in stainless steels is often inferior to the parent metals, and is an important factor to consider during the selection of materials of service in corrosive environments. Notes that an empirical pitting resistance equivalent (PRE), often expressed as PRE = % Cr + 3.3 × % Mo + 16 × % N, is used to rank ...
