This paper presents a novel approach to welding thick steel plates that offers time and energy savings compared with conventional techniques. The combination of gas metal arc (GMAW) hot-wire technology simplifies the joint configuration enhances process tolerance. In this study, square butt was prepared as-cut edges thickness 15 mm. relationship between current deposition rate solo GMAW showed ...

The process of Wire Arc Additive Manufacturing (WAAM) utilizes arc welding technology to fabricate metallic components by depositing material in a selective layered fashion. Several processes exist that can achieve this deposition strategy. Gas Metal Welding (GMAW) derived are commonly favored for their high rates (1–4 kg/h) and minimal torch reorientation required during deposition. A range GM...

Abstract Gas metal arc welding (GMAW) process is one of the most important in industry, so different efforts have been made to anticipate parameters convert this into a stable capable joining parts with minimum human interference. In sense, controlling essential for automated applications because properties such as weld mechanical strength are defined by composition, microstructure, and bead ge...

ASTM A53 steel is medium carbon with 0.3% content and often used for pipe manufacturing. The purpose of this study was to determine the effect post heating temperature variation on bending metallography test weld joint using GMAW process. electrode ER-70S-6. Post variations are 250oC, 300oC 350oC. result showed that welding 350oC postheating produce smallest open defect value. microstructure pe...

Invar 36 alloy is of high interest in various industrial sectors, due to its reduced thermal expansion properties. This study aims validate Wire-Arc Additive Manufacturing (WAAM) technology as a valid method for manufacturing aerospace tooling 36. The main novelty and the objective this work properties deposited by WAAM provide guidelines manufacture parts using technology. To do so, behaviour ...

This paper presents a control system for manual pulsed Gas Metal Arc Welding (GMAW). This system consists of a current controller, which makes it possible to shape the current during welding, and two important components, which are the key issues discussed in this paper. These components include an arc length controller and a metal transfer controller. The arc length controller is based on a no...

Gas Metal arc Welding (GMABQ has become the most addely used process for joining of steel plates due to its high productixity, simplicity of equipment and ease of use. Although the process of melting of the electrode and development of the weld deposit has been studied for 40 years, the dynamic nature of the process has not been studied in detail because accurate models are computationally inte...
