METHOD FOR ASSEMBLING BUTT JOINT OF TUBES FOR WELDING

FIELD: building industry branch, namely assembling tubes for welding at constructing pipelines. ^ SUBSTANCE: method comprises steps of measuring geometry parameters of end of each tube to be butt joined; analyzing combination of tubes in butt joint during two stages; at first stage determining values of assembling parameters for large number of mutual position of tube ends along the whole perimeter of butt; at second stage selecting of all possible positions of tube ends such position for which target function including values of assembling parameters determined for first stage has extreme value. It allows to take into account real geometry of end of each tube at assembling, to preliminarily analyze main parameters of assembled butt joint and to select most optimal variant of mutual arrangement of tubes on base of analysis before assembling. ^ EFFECT: enhanced assembling accuracy, improved quality of welded tube joint, shortened time period for finding most optimal mutual arrangement of tubes for assembling. ^ 8 cl, 13 dwg, 1 ex
