The transfer modes in the Gas Metal Arc Welding (GMAW) process determine to a large extent the quality of the welded beam, which is why they are of such great interest to the scientific and industrial communities. This article presents two coupled models that aim to predict the transfer modes in relation to the process input variables: the arc voltage and the welding current. The first is a gray-box model with a phenomenological basis, which is used to obtain the current dynamic, the electrode… CONTINUE READING
