Considered is the method for restoration of performance of vertical assembly joints in a wall of coiled tanks by successive cutting out of regions of an aligned weld and welding instead of it the rectangular inserts with a girth arrangement of the vertical welds. It is shown that deviation of the inserts from their specified positions leads to formation of extra stresses along the vertical insert to shell joining line, as well as at the centre of an insert, which requires special allowances to be made for the deviation. Criterion for determination of allowances for deviation of rectangular inserts from their specified positions is suggested.
