Design and Devlopment of Virtual Metal Arc Welding

Abstract

The practical reality made humans to interact with computer systems to feel newlinereal world prevalent to modern day artificial cognitive technology. At present, newlineVirtual Reality (VR) is one of the evolving technologies that enable advancement in newlinehuman-computer interaction based on wide range of inputs. VR is a real time newlinesimulation of a virtual environment using human computer interface and facilitates newlinemultidisciplinary collaborative engineering. newlineWelding is one of the most important and inevitable functional activities in newlinemanufacturing and construction sector. The mechanical strength of the structure newlineincreases with high strength capacity of welded joints. Usually the welding trainers newlinein under-graduate universities and industries are not so expertise, in turn decreased newlinethe count of skilled welders and impacts the training of under-graduate trainers, newlinemanufacturing and several construction industries. The reason is because of high newlinecost in material, equipment maintenance, training and high carbon emission with newlineecological pollution. VR technology provides a suitable solution for the above newlineproblems, thereby achieving skilled trainers, reduction in material wastage, time newlinesaving, self-learning practice, reduction in outlay and increase in compatibility. newlineThe present research work describes design and development of user-fixed newlineVR system entitled Virtual Reality Metal Arc Welding (VRMAW) for the user to newlineexplore the sense of presence in virtual environment by seeing, hearing and feeling newlineof the welding process. VRMAW uses Human-Computer Interaction (HCI) to newlineexperience the immersive virtual environment usually difficult in conventional newlineenvironment. Design comprises of CAD modelling, virtual objects creation, newlinetransformation of coordinate systems, virtual reality environment and integration of newlineapplication with smartphone sensors. Developed mathematical framework for visual newlinedisplay transformations and introduced the Position-Rotation-Scaling (PRS) newlinerepresentation for the transformation between coordinate systems. newlineMore focused on 3D GUI o
