| The aim of this work is to determine the influence of Yb:YAG laser beam power distribution on the formation of a fusion zone in a laser-arc hybrid welded plate made of S355 steel. The laser beam heat source is modeled based on the geostatistical kriging interpolation method. The electric arc is modeled using classic Goldak's heat source power distribution. The hybrid heat source energetic parameters are assumed with respect to experimental research on Yb:YAG laser beam characteristics as well as on electric arc current and voltage obtained during the real heating tests. |
