Study of arc stability in underwater shielded metal arc welding at shallow depths
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2008The main objective of this work was to study the effects of changes in hydrostatic pressure and electrode coating composition on the shielding metal arc behaviour during underwater wet welding. Thus, wet welding operations were performed by an automatic device using a hyperbaric chamber to simulate depths of 5.0, 12.5, and 20.0 m.

Abstract Shielded metal arc welding (SMAW), commonly called stick or covered electrode welding, is a manual welding process whereby an arc is generated between a flux-covered consumable electrode and a workpiece. This article discusses the advantages and limitations and applications of the SMAW process and describes the equipment used ...

Weld Properties of Low Carbon Steel Using Shielded Metal Arc Welding
Applied Mechanics and Materials, 2015Welding is basic part of the most modern assembly and manufacturing operations. Shielded metal Arc Welding process has hard facing and fabrication job application due to low cost electrode, increasing alloy transfer efficiency and low dilution with substrate without losing production capacity.

Arc welding processes with shielding using active metals
Welding International, 1991Abstract Welding processes employing arc shielding using so-called active metals are proposed. The technique is based upon the air entering the arc atmosphere bonding together with the active metal vapour and its subsequent transfer into the slag.

Welding in the World, 2014
Mixed microstructures of δ-ferrite, martensite and bainite are common in the weld metals produced by self-shielded arc welding (SSAW) for the purpose of hardfacing weld repair. This paper describes the development of a Schaeffler-type diagram for predicting the weld metal microstructure, thereby providing guidance on weld filler metal design to produce

Computer Simulation in the Design of Local Exhaust Hoods for Shielded Metal Arc Welding
AIHAJ, 1990Computer simulations were used to examine competing exhaust hood configurations for shielded metal arc welding. The welder's breathing zone concentration appears to be an inverse linear function of the computer-predicted hood capture efficiency. Hood aspect ratio, hood flow, and the welder's position relative to the hood all have a significant effect ...

Comparison of the Weld Quality Created by Metal Active Gas and Shielded Metal Arc Welding
2019The aim of each engineer is to achieve the elimination of impact of welding technology on defects in the welding joint, resulting in weld joints of the required quality. The achieving of this goal allows for a modern welding technique that attempts to meet ever-increasing demands. This article is focused on the comparison of the welding quality created

Pipeline construction has been moving towards the use of higher strength low carbon steels as these become available. In order to achieve the required high strength and toughness to match those of the parent pipe, girth weld metals have to rely mostly on their composition.

Arc characteristics in gas-metal arc welding of aluminum using argon as the shielding gas
Journal of Applied Physics, 1993A mathematical model has been developed describing transport phenomena in gas-metal arc welding. In the statement of the model a cylindrical electrode was considered and attention was concentrated on representing the electrodynamic, heat-transfer, and fluid-flow phenomena in the plasma column.
