ABSTRACT:
A bracket of generally U-shaped cross-section comprising spaced-apart legs terminating in edges having projections thereon is joined to a cylindrical steel wall by a method that comprises the steps of: (a) locating the bracket so that said edges extend along the length of the cylindrical steel wall and said projections contact the external surface of the wall, (b) projection-welding the bracket to the wall by an operation that collapses the projections, locates the edges closely adjacent the external surface of the steel wall, and provides a gap of V-shaped cross-section between each edge and the external surface of the wall, and (c) then fillet-welding the bracket to the wall by applying a welding fillet to the external surface of the wall and the outer surface of each leg of the bracket in the region of the V-shaped gap.
