Human-centered augmented reality manual arc welding active safety design

With the modern welding equipment progressing continually and the human-centered concept being accepted widely, the technology degree and safety standards of welder are demanded to farther reinforce. These needs the design of manual arc welding shield should consider both protective capability and assistant performance. But the conventional protection shield which based on the design of machine-centered is difficult to meet two needs of modern manual welding protection. According to the ideas of active safety and human-centered, considering the deficiency of visual information and the human physiological characteristic during welding, a helmet shield design has been developed which replaces the conventional protection shield with a video see-through helmet, where additional information is provided supplying artificial assistant elements. This design which can commendably achieve two needs of modern manual welding protection is an innovative manual welding protection design.
