Hold preheat of flanges to 200 0 F minimum. Preheat web plate for 6 " to 8" each side <br />of centerline of the butt joint to o maximum of 200" F. Mointain the preheat and <br />weld web butt joint. Sequence of web give weld moy be bockstep, coscode or intermittent <br />so as to balance the applied web heat to the heat of the flanges, thus minimizing the <br />shrinkoge stresses. <br />5.
