A method of making an aerospace component, for example a spar for a wing of an aircraft is described. The method includes placing two billets (2, 4) of different alloy in abutting relation, there being no voids or channels formed therebetween, partial penetration friction stir welding together the two billets (2, 4) from opposing sides of the billets (2, 4), the welds (12, 14) so formed being separated by a central region (20) formed partly by one billet (2) and partly by the other billet (4), and then machining away material, for example with a milling tool. The machining is performed so as to leave no portion having a partial penetration friction stir weld, so as to remove all of the central region (20), and so as to form a multi-alloy spar having at least one transverse web section having a slot formed at least in part by the removal of the central region (20). The slot may be positioned midway between the far ends of the full-penetration friction stir welds (12, 14) that extend to either side of the slot.
