Abstract：

Experiment on laser bending of shipbuilding steel plate is performed.The influence of laser power,scanning velocity,number of scanning passes and the thickness of the plates on bending angle is studied by CO_(2) laser.The measurement of real-time bending angle and temperature during the laser bending process of shipbuilding steel plate is carried out.The experimental results show that:(1) The bending angle is increased with the increase of the laser power and decreased with the increase of laser scanning speed.The bending angle is decreased with the thickness of the plate.(2) The multiple-irradiation laser bending process is affected by laser parameters and the thickness of the plate.The bending angle is increased with the number of scanning passes.A linear relationship between bending angle and the number of irradiations is observed for the relatively thin plate.While the increase of bending angle gradually is decreased with each additional laser scanning for the thicker plate.
