TL;DR: In this paper, the relative influence of electrochemical and thermochemical reactions on the weld metal chemistry in a direct current submerged arc welding process was investigated, and chemical analyses were carried out on the melted electrode tips, the detached droplets and the welding metal for both electrode-positive (reverse) and electrode-negative (straight) polarity where the welding wire is cathodic.
Abstract: The purpose of this work is to investigate the relative influence of electrochemical and thermochemical reactions on the weld metal chemistry in a direct current submerged arc welding process. Chemical analyses were carried out on the melted electrode tips, the detached droplets and the weld metal for both electrode-positive (reverse) polarity where the welding wire is anodic and electrode-negative (straight) polarity where the welding wire is cathodic

TL;DR: In this article, the authors present the corrosion behavior of welded low carbon steel at different welding voltages and filler materials, and the results showed that the corrosion rate decreased when the welding voltage increased, as it directly affected the welding heat input.
Abstract: This paper presents the corrosion behaviour of welded low carbon steel at different welding voltages and filler materials. The welding process was conducted on butt joint specimens using the metal inert gas (MIG) technique at a welding voltage range of 19 to 21 V with 1 V interval, and the filler materials used were ER 308L and ER 70S-6 with 1.2 mm diameter. Heat treatment through full annealing was done to the welded low carbon steel, and the corrosion behaviour was tested using a synthetic seawater environment with 3.5 wt% NaCl. Microstructure changes were observed using a scanning electron microscope (SEM). The results showed that the corrosion rate decreased when the welding voltage increased, as it directly affected the welding heat input. The welding heat input was found to have a significant effect on the corrosion rate as it changed the ferrite content in the microstructure of the specimens. Decrease in the corrosion rate was also found when the full annealing process was done to the specimens and ER 308L filler material was used. From a metallographic study, iron oxides and pitting were found on the surface of the exposed area after the corrosion test. It is apparent that the combination of higher welding voltage, heat treatment and the use of ER 308L filler material can reduce the corrosion rate of AISI 1010 carbon steel.

TL;DR: In this article, the influence of titanium additions and interpass temperature on microstructures and properties in low carbon-15Mn-3Ni-05Mo multiple pass steel weld metals produced using the shielded metal arc welding (SMAW) process was studied.
Abstract: The influence of titanium additions and interpass temperature on the microstructures and properties in low carbon-15Mn-3Ni-05Mo multiple pass steel weld metals produced using the shielded metal arc welding (SMAW) process was studied Robust weld metals with high strength (>690 MPa) and toughness (100 J at -70°C) were produced when titanium concentrations of 180 to 400 ppm were added to a base chemical composition of low carbon-15Mn-3Ni-05Mo steels High toughness was measured in weld metals containing either 30 to 90 ppm titanium or 180 to 400 ppm titanium while deteriorated weld metal toughness was observed when weld metal titanium concentrations were less than 10 ppm, 90 to 180 ppm, or more than 400 ppm The microstructures of these low carbon weld metals were complex The difference between the classification systems used for weld metals and base metals was addressed
