Shrouding
Do you like this story?
Stiffness against vibration and correct guidance to the steam is essential. To meet these conditions the outer ends of the blades are usually tied together by a perforated ribbon of metal known as Shroud. In case where stress consideration is of primary importance, for example, the last row of the low pressure blades, the shroud is omitted. In longer blades of LP turbine, lasing or binding wires are also silver soldered to connect bundles of blades together at various radii.
