Automatización del visor de un casco de soldar mediante control de voz

Abstract

Automation refers to the use of technologies to perform tasks that require human labor. In the welding sector, automation emerges as a key solution to optimize processes, improve efficiency and employee safety, for which new technologies such as robots, computerized systems, sensors, etc. have been developed. A serious problem was identified, and it is that a certain percentage of welders during their working days prefer comfort to safety, because for them it is uncomfortable and tiring to be performing the action of raising and lowering the helmet visor manually and repetitively. For this reason, the development of a prototype of a welding helmet with an automated visor, capable of being controlled by voice commands, was proposed; therefore, the welder can raise and lower the visor only by voice, without having to lose concentration or use his hands, reducing the fatigue caused by doing this process manually. For the evaluation of the prototype, some key metrics were taken into account, such as response times for opening and closing the visor and the increase in the use of the helmet. Regarding the hypothesis, according to the results obtained with the observation sheets, it can be stated that the development of the prototype of an automated welding helmet using voice command and servomotor technologies increased the use of the helmet by welders by 9,16%. This prototype allows welders to improve protection, increase their use and work efficiency, all this thanks to innovation and the implementation of new technologies. These results support the feasibility and effectiveness of the prototype, underlining the importance of automation in the optimization of industrial processes.
