Resumen
El presente trabajo se desarrolla en función de obtener un software en plataforma MATLAB, para el cálculo de los costos de los procesos de soldadura por arco. Comprende el cálculo de los costos totales de soldadura por arco eléctrico de los procesos SMAW, GMAW, FCAW con protección y sin protección gaseosa, SAW y GTAW con varilla o con alambre continuo. Para su confección se seleccionó una metodología previamente elaborada sobre costos de soldadura con el objetivo de servir como base para la programación de dicho software. Fueron introducidas al programa las preparaciones de bordes de la Norma cubana NC ISO 9692-1 y NC ISO 9692-2 y la implementación de las tablas encontrada en la bibliografía. Se consideraron las regulaciones legales que se establecen en Cuba en el tratamiento de los costos de un producto. El software fue nombrado “WeldingCost”, tiene tres interfaces, la primera de igual nombre, es la presentación del programa, la segunda “Consumo de materiales de soldar” es la que calcula la cantidad de consumibles y abarca el uso de los aceros al carbono, aceros inoxidables, aleaciones de níquel, de aluminio y de titanio. La tercera ventana “Costos de soldadura” ofrece el costo total del proceso de soldadura por arco eléctrico. Para el uso del software elaborado fue creada una ayuda que comprende ejemplos demostrativos sobre el uso del mismo, la cual está insertada en el software. A modo de validación se realizaron 5 corridas de ejemplos de cálculo de costo para los procesos SMAW, GMAW, FCAW, GTAW y SAW y la comprobación de los resultados con los obtenidos por el método analítico.
This work is developed based on MATLAB software get a platform for the costing of arc welding processes. It comprises calculating the total cost of electric arc welding of SMAW, GMAW, FCAW protected without shielding gas, SAW and GTAW processes with continuous rod or wire. For making them a methodology previously developed for welding costs in order to serve as a basis for programming the software was selected. They were introduced to the program preparations edges of the Cuban Standard NC ISO 9692-1 and ISO 9692-2 and the implementation of the tables found in the literature. Legal regulations established in Cuba in the treatment of the costs of a product are considered. The software was named "WeldingCost" has three interfaces, the first of the same name, is the presentation of the program, the second "consumption of welding materials" is one that calculates the amount of consumables and covers the use of carbon steels , stainless steels, nickel alloys, aluminum and titanium. The third window "welding costs" provides the total cost of the welding arc. To use the software developed was created an aid comprising demonstrative examples on using the same, which is inserted in the software. As validation five runs cost calculation examples for SMAW, GMAW, FCAW, GTAW and SAW processes and checking the results with those obtained by the analytical method were performed.
