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

open access: yes, 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.

Hot Deformability of Weld Metal

open access: yesJOURNAL OF THE JAPAN WELDING SOCIETY, 1973
In order to study the mechanism of hot cracking in aluminum alloys, the characteristics of brittle range existing behind the molten pool are investigated experimentally by using special tension executed soon after the welding. As to the characteristics of brittle range in weld metal, length, temperature range and minimum quantity of deformation ...
