Abstract:This paper describes a real-time welding simulation method for use in a desktop virtual reality simulated Metal Inert Gas welding training system. The simulation defines the shape of the weld bead, the depth of penetration, and the temperature distribution in the workpiece, based on inputs from the motion-tracking system that tracks the position of the welding gun as a function of time. A finite difference method is used to calculate the temperature distribution, including the width of the weld bead and the de… Show more
Virtual reality (VR) and augmented reality (AR) continue to play an important role in vocational training in the current pandemic and Industrial Revolution 4.0 era. Welding is one of the highly demanded vocational skills for various manufacturing and construction industries. Students need to undergo many practical sessions to become skilful welders. However, conventional training is very costly in terms of material, time, and infrastructure. Hence, we explore the intervention of VR and AR in welding training, which includes the research purposes, VR and AR technologies, and welding concepts and activities. We performed a comprehensive search of articles from the year 2000 to 2021. After filtering through inclusion criteria and full-text assessment, a total of 42 articles were coded and evaluated. While there has been growth in VR and AR welding training research, there is little discussion in their effectiveness for supporting distance learning, and most studies targeted entry-level students. Our main contributions are classifying primary functions in the virtual welding workshops and their adaptation to the psychomotor domain. We hope these results can empower the research community to develop and improve the VR and AR system and evaluation instruments to support vocational training, especially during this pandemic.

“…Rozwiązanie to jest dość często stosowane w różnego rodzaju symulatorach, np. : do doskonalenia umiejętności w zakresie użytkowania pojazdów kołowych i maszyn budowlanych [4÷6], wózków jezdniowych podnośnikowych [7,8], lokomotyw, statków powietrznych, czy też operatorów tokarek [9], frezarek [10], automatów spawalniczych [11] oraz żurawi i dźwignic [3,12]. Innym sposobem odczuwania wrażenia dotyku podczas procesu symulacji jest wykorzystanie odpowiednich urządzeń z siłowym sprzężeniem zwrotnym.…”

“…Symulatory umożliwiają zanurzenie użytkownika w środowisku wirtualnym. Dzięki temu użytkownik może osobiście uczestniczyć w symulacji procesu pracy poprzez użytkowanie wirtualnych maszyn (tokarki [3], frezarki [4], suwnicy [5,6], spawarki [7], automatu malarskiego [8]), czy też obsługi wirtualnych pojazdów (kołowych [9], wózków jezdniowych [10], budowlanych i innych). Wykorzystanie symulatorów nie zastąpi tradycyjnych szkoleń na rzeczywistych maszynach lub urządzeniach, a jedynie podniesie ich atrakcyjność oraz umożliwi skrócenie czasu procesu szkoleniowego.…”
Streszczenie: W artykule przedstawiono koncepcję przeprowadzenia badań eksperymentalnych w aspekcie symulowania wrażenia dotyku związanego z manipulowaniem rzeczywistymi i wirtualnymi elementami sterowniczymi. Badania te pozwolą na określenie, które czynności związane z użytkowaniem maszyn do obróbki metalu można prowadzić z wykorzystaniem uproszczonego sposobu symulowania wrażenia dotyku (za pomocą wirtualnych elementów sterowniczych), a które z wykorzystaniem rzeczywistych elementów. W opracowanej koncepcji zawarto również wytyczne odnośnie do budowanego stanowiska badawczego obejmującego rękawicę z siłowym sprzężeniem zwrotnym oraz symulator wyposażony w fizyczne modele rzeczywistych elementów sterowniczych. Badania przeprowadzone zostaną z wykorzystaniem techniki VR.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
