In laser beam welding of aluminum alloy there is a high susceptibility of pore formation at low feed rates. Porosity can be improved by application of several laser spots to form the shape of the vapor capillary. In this regard, flexible, concentrica

Compared to steel, the required amount of energy for conventional welding of copper is higher, due to its higher thermal conductivity. This problem is mainly solved by preheating the work pieces or welding processes with high intensities such as lase
