Paper Abstract

In the paper the authors present results about research dealing with deformations of low-carbon samples influenced by a stagnant or not moving CO2 laser impulse. Permanent and non-permanent deformations were analysed for two cases: for constant power and for constant maximal surface temperature. Laser-based forming methods known till now, use moving laser beams. As a results of the paper it is found, that in case of constant power (for each experimental points) non-permanent (temporary) deformation decreases with pulse duration and permanent (residual) deformation is maximal for some pulse duration. But in case when surface temperature is kept constant, non-permanent deformation is constant with pulse duration and curvature of permanent deformation can be positive negative or kept zero. Aim of the research is to show possibility of laser forming by a not moving laser beam with suitable power and pulse duration with control of sample residual curvature.
