Recycling of submerged arc welding slag for sustainability [PDF]

Production and Manufacturing Research: An Open Access Journal, 2020
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 ...

A novel approach of ultra-low diffusible hydrogen welding wire for underwater wet flux-cored arc welding: a spontaneous barrier of molten slag

Journal of Materials Research and Technology, 2023
In underwater wet welding, a hydrogen-rich arc atmosphere generated by the thermal decomposition of water leads to extremely high diffusible hydrogen content and defects such as pores and cracks in the weld.

Metallurgical Model of Diffusible Hydrogen and Non-Metallic Slag Inclusions in Underwater Wet Welding of High-Strength Steel [PDF]

Metals, 2020
High susceptibility to cold cracking induced by diffusible hydrogen and hydrogen embrittlement are major obstacles to greater utilization of underwater wet welding for high-strength steels. The aim of the research was to develop gas–slag systems for flux-

Highly efficient oxidation of Panzhihua titanium slag for manufacturing welding grade rutile titanium dioxide

Journal of Materials Research and Technology, 2020
Because of the shortage of natural rutile, synthetic rutile is a widely used substitute welding materials for natural rutile owing to its excellent mechanical and thermal properties. In this work, rutile TiO2 was prepared from oxidation roasting titanium

Welding Slag Clear Machine with Kinematic Linkage Indexer

IOSR Journal of Mechanical and Civil Engineering, 2014
Welding slag is a form of slag or vitreous material produced as a byproduct of some arc welding processes, most specifically Shielded metal arc welding , Submerged arc welding, and Flux-cored arc welding.Slag is the leftover remains of the weld process that is a result of the flux having done its job.

Study on Submerged Arc Welding Slag Recycling for Stainless Steel Welding: A Review

, 2023
The submerged arc welding process is the type of fusion welding process that uses a continuously moving electrode towards the workpiece. The granular flux is used in submerged arc welding, which is kept in the hopper and flows through the nozzle ahead of the weld pool.

Use of furnace slag and welding slag as replacement for sand in concrete [PDF]

International Journal of Energy and Environmental Engineering, 2013
In this project, a study was made to obtain low cost building materials using industrial wastes (welding and furnace slags). The objective of the study is to use these wastes in low-cost construction with adequate compressive strength. Different fine aggregate replacements have been studied by substituting 5%, 10%, and 15% of slag.
