A model comparison to predict heat transfer during spot GTA welding [PDF]
, 2013 The present work deals with the estimation of the time evolution of the weld fusion boundary. This moving boundary is the result of a spot GTA welding process on a 316L stainless steel disk. The estimation is based on the iterative regularization method.
