A method of securing a lagging component to a metal surface, comprising: positioning a prefabricated lagged component having one or more holes on the metal surface; inserting a securing element into each hole of the lagging component until its end touches the metal surface; welding the securing element to the surface using a welding gun; and filling the remaining hole cavity with a packing material around the securing element. The securing element is held in place prior to welding by a cardboard retainer.
