Paper Abstract

The possibility of the rust and paint removal from the power transmission towers was investigated with the pulsed Nd:YAG laser for the first time. The red rust and paint were successfully removed without damaging underlying Zn(zinc) galvanized steel substrates. The optimum irradiated laser fluence for the red rust was found from 0.3 J/cm2 to 0.4 J/cm2 for 9 ns short pulses, from 1.0 J/cm2 to 4.4 J/cm2 for 200 ns long pulses, respectively. For the paint stripping the optimum ranged from 3.3 J/cm2 to 4.4 J/cm2 with the pulse width of 200 ns.
