Vg. Michailov et M. Stadtaus, Some problems of the FE-simulation of the hydrogen and nitrogen distribution in the welding, Z METALLKUN, 92(3), 2001, pp. 247-252
Cases like hydrogen or nitrogen which are locked up in the weld affect the
characteristics of the welded joint. But a quantitative, experimental deter
mination of the gas distribution during the welding process is currently no
t possible. An alternative way offers the numerical simulation based on the
finite element method. The results show that the thermal diffusion - depen
dent on the material - has a different influence on the gas distribution.
