Hybrid Nugget Diameter Prediction for Resistance Spot Welding
Procedia Manufacturing, 2018 Abstract Resistance spot welding (RSW) is one of the critical joining methods in sheet metal-based industries. The nugget size is a crucial factor, which determines the stoutness of final products. In this research, we present a hybrid prediction method based on a theoretical physical model and a machine learning method (i.e., spline-based ...

, 2023 AbstractEver new requirements for the environmental compatibility and safety of products do not stop at the automotive industry. This results in ever shorter time windows for the pre-series processes. For this reason, time-consuming preliminary tests must be minimized to ensure an accelerated start-up and production that is as trouble-free as possible.
