Abstract:The explicit temperature function of dual laser
welding was presented, and the effect of welding pass distance
and heat source distance on the thermal history was analyzed.
There was excellent correlation between analytically solved
and finite element method (FEM)-predicted dual laser
welding temperature field. The analytical temperature function is applied to study the static recrystallization kinetics upon dual laser welding of nanobainite steel. By calculation, the
optimal welding process parameters can be obtained when the
static recrystallization fraction takes the maximum value. The
corresponding temperature is above the martensite transus
temperature and is appropriate to produce sufficient plastic
strain in the austenite grains.
