This paper concerns the mathematical and numerical modeling of thermal phenomena in the laser-arc hybrid welding process with the motion of liquid steel in the welding pool taken into considerations. Developed models are used in computer simulations of hybrid welding process with assumed different relative arrangement of heat sources in the process. The shape and size of the welding pool is numerically estimated. Numerical predicted hybrid welded joints are compared to macroscopic pictures of cross sections of experimentally obtained welds.Keywords: Hybrid welding, relative arrangement, heat source, numerical modeling, welding pool
