Melt Pool and Keyhole Behavior Analysis for Deep Penetration Laser Welding [PDF]
One usually defines the main characteristic of the welding performances of a given laser system by its “penetration curve” that corresponds to the welding depth as a function of the welding speed Vw for a given set of operating parameters.

MODELING OF THE WELD BEAD SHAPE AT DIFFERENT WELDING PARAMETERS [PDF]
ABSTRACTThis paper tends to discuss the relation between welding parameters (Voltage, ArcCurrent and Travel Speed) and the deposited lines shape (width, height andpenetration) in metal deposition process. Due to the high nonlinearity of the processANN (artificial neural network) was found to be the best chose for representing it.ANN is trained off-line

A model comparison to predict heat transfer during spot GTA welding [PDF]
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.

Shear strength optimization for FSSW AA6060-T5 joints by Taguchi and full factorial design
Statistical tools have shown to be very useful in the optimization of processes such as welding. Optimization is understood as the determination of the welding combinations that will lead to the maximization of a desired property, such as strength.
