The influence of welding arc regime on the fumes formation is studied by numerical modeling via description separate processes inside space charge regions near electrodes in with consumable electrode. comprises calculation temperature profiles for electrons and heavy component, distribution gas components’ number densities, particles’ mean free pathes, electric potential field, heat transfer fr...

Welding is one of the most complex industrial processes because it challenging to model, control, and inspect. In particular, quality inspection process critical a time-consuming activity. This research aims propose system online welded items with gas metal arc welding (GMAW) technology through use neural networks speed up process. following experimental tests, deviations parameters—such as cur...

Cracking is a major concern in welding aluminum alloys. Although weld solidification cracks can be eliminated through the addition of filler metal, the additives modify the alloy or base metal constituents and may not always be desirable. High-energy beam processes, such as electron beam welding, that result in minimal heat input reduce crack sensitivity, but their high cost limits their applic...

In this contribution we present a robot assistant consisting of a mobile platform and a manipulator to support manual workplaces in production environments. We propose a general definition of robot assistants. Two applications for the robot assistant rob@work are described – the assembly of hydraulic pumps and the assistance of manual gas metal arc welding (GMAW). A description of the hardware ...

Submerged arc welding also known as sub arc welding has become a chief welding process because of its ability to deposit large amounts of metal with high penetration. The quality of weld depends on bead geometry of the weld which in turn depends on the process variables. This paper deals with the application of factorial design approach for optimising four submerged arc welding parameters viz. ...

Abstract Heat input is a key component of welding procedure, which dependent on the several fall voltages composing total voltage loss. As current practice primarily reliant trial and error to determine settings for desired heat input, means understand predict loss interest engineers. Voltage, amperage, arc length measurements using ER4043 1.2 mm at varying were used break down constituents giv...

This paper develops an automatic welding control scheme for alternating current shielded metal arc welding (SMAW) system. A mathematical model of the welding control system is derived and the system parameters identified. An adaptive sliding mode controller is designed to estimate the bound of the system uncertainties and to modulate the electrode feed rate in such a way that the desired arc le...

Abstract Welding operation decides the quality of product standards in all metal work products like automobiles, aerospace vehicles, and many more. The welding process is more reliable by automating with robots. In this research work, GMAW automated ‘Fanuc Robot Arc mate 100iC/12’ robot. material characteristics such as ultimate tensile strength, hardness, impact strength weldments are predicte...
