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 ...

Critical Nugget Diameter of Resistance Spot Welded Stiffened Thin Plate Structure
Modern Applied Science, 2013 Stiffened thin plate structure which is mostly applied to the car body structures consists of frame and sheet. It is a low cost method to reach a high-performance vehicle structure because of requirement low volume materials. Frame is thicker than sheet, so it acts as the reinforcement of this structure.
