Abstract
Mathematical model is described, which was developed for prediction of overall bending distortions of long beams in laser welding to optimise the distance between the fixing supports, at which deviation of the laser beam from the joint site is not in excess of the admissible value.
Keywords: laser welding, welded beams, overall bending distortions, fixation system, numerical investigation
