Microstructure behavior in GMAW 2205 duplex steels welding for offshore applications

open access: yesMinería y Geología, 2022
This work evaluates the behavior of microstructure in the GMAW of 2205 duplex steels welding for offshore applications. Welding is performed with two input energy levels, 1.5 kJ/mm and 2.5 kJ/mm.

Modeling of Thermel Transport for GMAW

open access: yesMathematical Problems in Engineering, 2012
Investigation of temperature distribution of submerged arc welded plates is essential while designing submerged arc welding joint because the key parameter for the change of weld bead geometry dimension, thermal stress, residual stress, tensile stress, hardness, and so forth is heat input, and heat input is the function of temperature distribution of ...

Improving the GMAW process through current control

open access: yesCoRR
A control strategy for the electrical current in GMAW processes is proposed. The control is in closed-loop, designed by formal methods, based on a mathematical model of the electrical behavior of the GMAW process, and implemented in C+ language in a microcontroller.

Study of Effect of Electrode Arrangement on Layer Geometry and Fusion Zone Morphology under Twin-Arc Surfacing

open access: yesAdvanced Engineering Research
Introduction. Increasing the productivity of single-wire surfacing through raising the wire feed rate causes defects — undercuts and poor fusion between layers, which reduces the quality of the deposited coating and increases the reject rate.

Quantitative Evaluation of Fusion Zone Curvature Correlation with Electrode Positioning in Shielded Gas Split-Arc Surfacing

open access: yesAdvanced Engineering Research
Introduction. Improving the efficiency of arc surfacing with a consumable electrode is one of the key vectors in the development of modern manufacturing. Split-arc gas-shielded welding with a consumable electrode is of particular interest.

Evaluation of Melting Efficiency in Cold Wire Gas Metal Arc Welding Using 1020 Steel as Substrate

open access: yesMetals
A key welding parameter to quantify in the welding process is the ratio of the heat required to melt the weld metal versus the total energy delivered to the weld, and this is referred to as the melting efficiency.
