The integration of Augmented Reality (AR) in welding training is considered to increase the efficiency, security and time gain in operations, reducing consumable and infrastructures costs. Prior research has examined the integration of AR-simulation in applications, like medical operations or aviation, showing the need for greater usability of these systems. However, research on AR integration in welding training is yet limited. It can help new welders learn effectively and be prepared to work in the industry. The motivation of this study was the ongoing use of AR in manufacturing training and its novelty is the analysis of the most significant factors affecting the actual AR system use. The main objective of this research is to evaluate the use of AR technology in welding training using an innovative model, appropriately extended to consider pedagogy and technology. The contribution of this paper is the exploration and understanding of the factors associated with the AR welding training which can lead to goal fulfillment and, subsequently, impact users’ choice. This study is based on a modified Technology Acceptance Model, extending it by two external variables (perceived enjoyment and system quality) and the sample is 200 trainees. The findings show that the external variables are predictors of perceived usefulness and ease of use. The intention to use AR simulator is positively influenced directly by system quality and perceived ease of use. The findings help AR developers enhance the quality of AR-simulation training systems to enhance users’ experience and their behavioral intention to use them.

增强现实（AR）在焊接培训中的集成被认为可以提高操作效率，安全性和时间，减少消耗品和基础设施成本。先前的研究检查了AR模拟在医疗操作或航空等应用程序中的集成，表明需要提高这些系统的可用性。但是，关于焊接培训中的AR集成的研究还很有限。它可以帮助新的焊工有效地学习并做好在行业中工作的准备。这项研究的动机是在制造培训中不断使用AR，其新颖性是对影响实际AR系统使用的最重要因素的分析。这项研究的主要目的是使用创新模型评估AR技术在焊接培训中的应用，适当扩展以考虑教学法和技术。本文的贡献是对与AR焊接培训相关的因素的探索和理解，这些因素可以导致目标实现并随后影响用户的选择。这项研究基于修改后的技术接受模型，并通过两个外部变量（感知的享受和系统质量）对其进行了扩展，样本为200名受训者。研究结果表明，外部变量是感知有用性和易用性的预测指标。使用AR模拟器的意图直接受到系统质量和易于使用的感知的积极影响。这些发现有助于AR开发人员提高AR仿真培训系统的质量，从而增强用户的体验以及使用它们的行为意图。本文的贡献是对与AR焊接培训相关的因素的探索和理解，这些因素可以导致目标实现并随后影响用户的选择。这项研究基于修改后的技术接受模型，并通过两个外部变量（感知的享受和系统质量）对其进行了扩展，样本为200名受训者。研究结果表明，外部变量是感知有用性和易用性的预测指标。使用AR模拟器的意图直接受到系统质量和易于使用的感知的积极影响。这些发现有助于AR开发人员提高AR仿真培训系统的质量，从而增强用户的体验以及使用它们的行为意图。本文的贡献是对与AR焊接培训相关的因素的探索和理解，这些因素可以导致目标实现并随后影响用户的选择。这项研究基于修改后的技术接受模型，并通过两个外部变量（感知的享受和系统质量）对其进行了扩展，样本为200名受训者。研究结果表明，外部变量是感知有用性和易用性的预测指标。使用AR模拟器的意图直接受到系统质量和易于使用的感知的积极影响。这些发现有助于AR开发人员提高AR仿真培训系统的质量，从而增强用户的体验以及使用它们的行为意图。
