Process optimization and modeling using support vector regression in automatic flux cored arc welding for st 37 steel
This paper presents an integrated application of design of experiments (DoE), with support vector machine (SVM) for manufacturing process modeling in order to achieve a high accuracy model. The proposed method is as follows. Firstly, DoE is applied to indicate the critical parameters of the process....

This paper presents an integrated application of design of experiments (DoE), with support vector machine (SVM) for manufacturing process modeling in order to achieve a high accuracy model.

Data obtained from designed experiments were used in the training process. Finally, a grid search was adopted to the SVR model to find the optimum parameter setting. Data from real experiments of automatic flux cored arc welding (FACW) for ST 37 steel were used to demonstrate the proposed method.
