摘要
When flame cutting a tube by machine or welding at least one branch tube to a tube, in order to avoid welding or cutting defects caused by lateral displacement or by incorrect guidance of the rotating tube over the drive rollers (slippage), it is proposed to measure the actual rotational angle ( gamma ) of the tube (1) and/or the actual rotational speed (v) of the tube (1) and/or the axial and/or the radial actual position (Xs, Xr) of the tube and, in the event of deviations of the actual values from desired set values, to make corresponding adjustments to the torches or welding-head movement (4) or the tube (1).
