ABSTRACT:
A gas burner (10) includes an internal cavity (20) for receiving a gas and air mixture and an external substantially cylindrical wall (16) surrounding the cavity (20). The wall (16) is provided with through holes (32) for allowing gases to pass from the cavity (20) to an exterior burner (10) for combustion. The wall (16) is made up of one or more wall elements (30) in the form of sheets of material shaped so that together they form a substantially cylindrical shape. The wall includes at least one join between adjacent edge portions (34a, 34b) of the wall elements, the join being welded and at least the part of one edge portion (34a) overlying at least a part of the other edge portion (34b) in the region of the join.
