Investigation on laser induced thermal stress bending

In the paper,the bending behavior of low carbon steel sheets is studied after being irradiated by an axial CO2 laser beam.The results show that the final bending angle of the sheets in a multiple-irradiation laser bending process is related to many process parameters,especially laser power,beam diameter,path feed rate,number of irradiation and sheet thickness.Through qualitative analysis of the experimental results,the conclusion obtained may provide basis for theoretical investigation and possible industrial application of laser bending process in the future.
