Building Up Mathematical Modeling Using Spot Welding Parameters and Prediction Weld Nugget by Minitab

In serial production, problems are constantly encountered in the selection of welding parameters due to excess and variations. order compensate for these variations, mostly high energy flux is used. this study, an approach developed estimate weld nugget diameter determining sheets with a thickness 0.6-3 mm introduced. Minitab statistical program was used create experimental data mathematical operations. First all, 7 source were selected design (DOE) carried out 64 experiments using ½ partition factorial method software. With experiments, real diameters obtained. These results transferred software model system established. Weld estimation procedures data. Test prediction software, regression graph drawn R-Sq (adj) values calculated. addition, samples created randomly verification comparison made by transferring them Minitab. According remarkable accuracy rates have been achieved
