The present study investigates the electrochemical corrosion response and tribo-behavior of 304L 316L stainless steel welded by gas metal arc welding (GMAW), which offered a high deposition rate. During this research, metallurgically prepared samples were subjected to tribological test test. wear results favorable for steel, it showed lower coefficient friction than specimen. These also underwe...

Gas metal arc welding (GMAW) is a process in which an electric formed between wire electrode and workpiece alongside shielding gas to protect the from contaminants. There are several ways molten droplet can be transferred weld pool known as transfer modes. Identifying mode automatically essential monitor control process, especially automated processes employed modern Industry 4.0 manufacturing ...

An important trend in recent ships and offshore structures is that they require high strength as well light weight. Due to this trend, various materials are being used replace existing carbon steel, with aluminum alloys frequently. In particular, conspicuous outfitting rather than traditional structural members. As a typical example, the use of increasing helideck handrails, which tertiary comp...

In the present work, an analysis of different welding parameters was carried out on stainless-steel thin thickness tubes by Gas Metal Arc Welding (GMAW) process. The influence three main parameters, voltage, movement angle, and current in quality welds, studied through a specifically designed experimental process based establishment levels values for each these parameters. Weld is evaluated usi...

A main problem raised by arc welding manufacturing is the determination of the optimal process parameters to ensure weld quality as well as resource efficient and sustainable production. To address this problem a better process understanding is required. In this study thermal magneto hydrodynamic modeling of a welding arc is used to reach a deeper insight into the influence of the composition o...

This paper is focused on the study and the control of a deposition process of robotic arc welding. The process consists of a SMD (Shaped Metal Deposition) system, that is a novel rapid prototyping tungsten inert gas (TIG) welding technique leading to near-net-shape, using a layer by layer deposition technique. An experimental setup has been properly implemented in order to study the system and ...

The profile of the welding bead changes with process parameters during gas metal arc (GMAW) process, top reinforcement disappears, and penetration becomes sunken when excessive heat input is applied. However, little research work specially planned to cope studying under these circumstances. A systematic study relationships among variables geometric features as well optimization quality presente...

A mathematical model to describe the globular transfer in gas metal arc welding is developed. This work is both theoretical and experimental. Using the volume-of-fluid (VOF) method, the fluid-flow and heat-transfer phenomena during the impingement of a droplet on a solid substrate, arc striking, the impingement of multiple droplets on the molten pool and finally the solidification after the arc...
