Abstract
To enhance the performance of spot weld joints, various improvement methods are used to strengthen the properties of welded joints. Spot welding process is very well suited for welding of various steels grades. Regression analysis is the statistical modeling technique, and it is suitable for predicting strength of welded joints. It is valuable for quantifying the impact of various loading types upon a spot weld rupture.In the present study quantification of impact strength of spot welded EHSS steel, Mild Steel (DC05) and AHSS (DP780) were carried out, by developing the regression models. The analysis includes Material, Thickness, Test type, Test Speed as process parameters. The complete analysis will be helpful in deciding the best combinations for desired performance characteristics. Taguchi technique revealed that the impact speed is the most significant factor in weld strength followed by thickness and material grade.
