Fusion-diffusion electron beam welding of aluminum‑lithium alloy with Cu nano-coating

Materials & Design, 2020
As a new method to reduce the temperature in melt pool and subsequently alleviate the Li evaporation loss, fusion-diffusion electron beam welding is proposed for aluminum‑lithium alloy joining achieved by defocused electron beam and pressure.

Adaption of a topographical measurement system for beam welding processes with high temporal and spatial resolution

Journal of Advanced Joining Processes, 2020
Both typical beam welding processes laser beam welding LBW and electron beam welding EBW feature the deep penetration welding process. Theses processes rely on a vapor capillary with a delicate, highly dynamic equilibrium of various opposing forces.

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.
