El presente estudio expone la implementación de un dispositivo poka-yoke en una máquina de soldadura eléctrica para fabricación de malla de acero con el objetivo de eliminar defectos por inserción incorrecta del alambre transversal y optimizar la productividad. Mediante un enfoque cuantitativo de campo, se aplicaron herramientas de manufactura esbelta: 5 porqués para el análisis de causas raíz y listas de verificación para el monitoreo. El dispositivo reforzó el soporte transversal, previniendo deformaciones durante la soldadura. Los resultados mostraron una reducción total de mallas defectuosas y un incremento del 23,68 % en productividad. La tasa de defectos, que antes era del 39,5 % por turno, se redujo a cero, cumpliendo todas las mallas con especificaciones de calidad. Con ello, se confirma que soluciones poka-yoke simples y rentables mejoran procesos industriales en el sector del acero.
