FIELD: pipes.
SUBSTANCE: invention relates to pipe scanning method, intended for processing at laser cutting machine. Method includes stages, at which: a) emitting focused laser beam by cutting head (50) of laser cutting machine so, that to prevent pipe material (T) cutting or etching; b) moving cutting head (50) along scanning specified direction (x); and c) during cutting head (50) movement along scanning direction (x) detecting by means of corresponding radiation sensors (56), reflected or irradiated by pipe (T), and install successively point by point, based on signal provided by sensors (56),
presence or absence of pipe material (T).
EFFECT: invention enables to measure cutting point position on pipe surface regardless of pipe position on laser cutting machine and from pipe shape.
