Use of audible sound for on-line monitoring of gas metal arc welding process [PDF]

open access: yesMetalurgija, 2008
In this paper sound generated during the gas-metal arc welding process was studded. Experimental analyses of the acoustic signals have shown that there are two main noise-generating mechanisms, first having impulse form is arc extinction and arc ignition;

Multiwire submerged arc welding of steel structures [PDF]

open access: yes, 2012
The assembly of large structures made out of thick steel plates requires a welding process by which multiple wires can be used simultaneously. To reproduce these industrial processes in a research environment, OCAS has invested in a multiwire submerged ...

Thermodynamic Constraints and Prospects for Intensified Steel Deoxidation

open access: yessteel research international, EarlyView.
The article provides a short survey of steel deoxidation and considers how to increase its efficacy. Bringing a specially tailored, powdered slag into the reaction site can directly bind the deoxidation product oxides, resulting in lower dissolved oxygen activity, total oxygen content, and cleaner steel.

Power arc welder touch-started with consumable electrode [PDF]

open access: yes, 1966
Power arc welder formed as a hand-held welding gun touch-starts, retracts a consumable electrode to create the desired arc, and then commences feeding of the consumable electrode at the rate required to form the intended bead or spot.

Phosphorus Partition in an Industrial Basic Oxygen Furnace Process in Ukraine

open access: yessteel research international, EarlyView.
Phosphorus partition data from Ukrainian steel plants are analyzed, focusing on parameters like basicity, optical basicity, tapping temperature, and slag contents of FeO, MgO, and Al2O3. The analysis shows that phosphorus partition decreases with higher tapping temperatures and increases with optical basicity.
