Abstract
Widely used in industrial environments, welding is a very old process that has been optimized over the years. Due to its ease of operation, relatively low cost and high productivity, the GMAW process is one of the most widely used types of welding. As in most industrial processes, welding also requires the correct dimensioning and control of mechanical properties. The aim of the present work is to develop an electronic calculation tool for the sizing of a weld bead obtained by GMAW process, where the user can enter with stress values and the dimensions of the weld bead and the program Return whether the welded joint will withstand the stress. To cover a larger number of people who could use this tool, the software chosen for the spreadsheet was “Microsoft Excel”. This spreadsheet was developed based on the equations found in the "Mechanical Engineering Design" literature by J. E. Shigley, et. al. To validate the results of the spreadsheet, test specimens were prepared, which were submitted to tensile tests. It was concluded that the spreadsheet calculates the welded joint subjected to tensile stresses correctly, but with a margin of safety, since, through the experimental tests, it was found that the joint still supports a load larger than calculated by the spreadsheet.
