Description

<p>Alumina particles were added in the adhesive layer to stabilize the welding process and enhance the load capacity for weld-bonding joints. In this study, the strength of alumina particles reinforced weld-bonding joints of DP780 dual-phase steel sheets was investigated by conducting experiments based on the Box–Behnken Design (BBD). The multivariate regression models between process parameters (welding current, welding time and electrode pressure) and response values (failure load, nugget diameter) were established, and the optimal combination of weld-bonding process parameters was obtained. The findings indicate that welding current has the biggest impact on the strength of joints. The optimum process parameters ranges are: welding current of 8.5 kA, welding time of 125 ms, and electrode pressure of 0.5 MPa. Developed regression models were validated by experiments.</p>
