An advantage offered by laser brazing over fusion welding is that stro
ng joints can be produced at a relatively low heat input. To minimize
the thermal effects and maintain the designed dimension of assemblies,
the CO2 laser beam was applied to the brazing of joints between a pin
and a hole as a micro heat source. The heat flow and temperature dist
ribution of the brazed parts were calculated using the finite element
method with a two-dimensional axisymmetric model and the surface tempe
rature of the brazed joint was measured with laser brazing by using a
infrared radiation sensor system. The laser beam mode was considered a
s a process parameter and its influence was predicted with respect to
the temperature distribution and joint quality through finite element
analysis. The measured and calculated results were compared with each
other, showing fairly good agreement. Based on these results, the prop
er process parameters were selected to obtain a good joint quality. (C
