Desenvolvimento de aplicativo como facilitador na utilização do diagrama de Schaeffler a fim de prever a microestrutura do metal de solda de aços inoxidáveis

Abstract

The present academic paper has as its theme the development of an application which function is to simulate a Schaeffler Diagram, in order to guide welding professionals easily and quickly, as a facilitator in predicting problems in the microstructure of stainless steel welded metal and with the specific objective to identify the microstructure obtained in the welding of stainless steels faster than usual. The methodology applied in this work is the descriptive research, with quantitative approach. By approaching the characteristics of stainless steels, the welding process of these steels and the Schaeffler Diagram it was possible to understand which microstructures can be expected in welding. To help to predict the microstructure of welding stainless steels, an application has been developed to calculate chromium and nickel equivalents based on the chemical composition of the base metal and filler metal informed by the user and able to predict the microstructure formed in the weld. Solder through the Schaeffler Diagram. The application allows the user to perform a vast amount of different types of metals, due to the database of base metals and addition metals. The application also enables faster welding simulations, optimizing decision-making. In sum, the application aims to increase reliability and agility in decision making by optimizing the productivity and quality of a project.
