Investigation on the Simulation System of GTAW Operation Based on Virtual Reality Technology

Abstract

Gas shield Tungsten Arc Welding (GTAW) is an important process method in material processing. Welding quality is vital for the product quality. It is an important way to improve the quality of product by raising the personal capability and handling technique of the welder. In this investigation, because of the deficiency in classic welding training scheme, some new technology were introduced into classic welding training field to improve the efficiency of welding training and reduce training cost. A computer simulation system that can be used to train primary welders was developed combined with three-dimensional stereoscopic vision and API interface of OpenGL, virtual reality is the kernel technology. In this system, welders were trained not in the real operating environment but in the virtual environment where has experience personally effect that simulated by computer. There is unnecessary with welding material and welding energy in virtual environment simulated by computer. It has highly automatic and intelligent and lower required to welding teachers. It is healthy to welder because that intensive arc and harmful dust are disappeared in virtual environment. It is a lower cost and high efficiency method by use of virtual training system to training new welder.

“…At this moment, electronic scattering is enhanced that is to say conductivity decrease with the increasing of temperature. It is called metalloid conductive mechanism [6].…”

VR and AR virtual welding for psychomotor skills: a systematic review

“…Benson et al [6] calculated the accuracy rate of their subjects to maintain the correct CTWD and welding speed. Although many studies mentioned the welding performance metrics for post-assessment [4,18,32,51], only a few studies evaluated these metrics' accuracy by comparing them with ideal values. Since there are ideal performance metrics for every welding position level, future researchers could utilise these ideal metrics to calculate the error rate of the trainees.…”

“…We elaborated on these studies on two main topics: subsection 3.3 described the devices used in building the virtual welding simulators; subsection 4.1 explained the functional requirements and interaction methods used by the previous studies. The studies in SD2 usually improved the realism of the virtual welding simulation [24,32,55], such as the weld bead visualisation, particle effect to simulate the welding spark, audio effects and realistic haptic feedback. Past research stated that simulating the virtual training environment with a high level of realism and using real-life welding tools as user input could increase the cognitive and psychomotor skills of the trainees [48].…”

Research on the virtual reality technology of a pipeline welding robot

“…In addition, this technology can be used for the diagnosis, risk assessment and therapy of child abusers (Fromberger and Müller, 2018). Virtual reality is also beneficial for welders because they do not need to touch the real welding rods and welding guns and they only need to master operation in the virtual environment (Liang et al , 2008). Virtual reality technology and discrete event simulation technology provide a modeling method for a virtual manufacturing system (Liang et al , 2005).…”
