Abstract: The method includes determining an oxide layer removal energy density threshold from a section of the product, including transmitting, to a segment of the section, analyzing pulses of wavelength and of pulse duration equal to those of the stripping lasers to form a stripped region, capturing an image of the segment, determining, from this image, a dimension representative of the stripped region and evaluating, from the dimension, the removal energy density threshold; transmitting stripping pulses to the section, the energy density of the stripping pulses being higher than the removal energy density threshold, the stripping laser being controlled in such a way that every point of the section is exposed to an energy density higher than the removal energy density threshold.

Abstract: The invention relates to a facility for treating a moving long product made of metal having a surface coated with a layer of oxide, comprising a stripping assembly comprising a group of lasers that are distributed around the long product a control unit for acquiring information relating to the long product the control unit being configured to determine operating parameters to be dictated on the stripping assembly in order to strip of the layer of oxide and to ablate a layer of metal of predetermined thickness, and so to obtain a predetermined roughness at the long product by comparing same with the experimental results pre-recorded in the control unit and dictating the operating parameters to the stripping assembly.
