FIELD: plastic metal working. SUBSTANCE: in agreement with process remains after cutting of profiles into rods of measured length which are assembled in sets of several pieces so that total length of cuts in each set is longer than length of rod of measured length not less than by summary value of allowance for welding of needed number of welded joints are used in the capacity of billets. They are but-welded is sequence by several wells, flash is removed and remains are cut to dimension of rods of measured length. EFFECT: improved functional efficiency of process.
