A method for forming a body by deposition of a weld material comprises providing a welding head (12), and providing support means (34) to support the body. The welding head (12) and the support means (34) are connected to a supply of electricity to form an arc between the welding head (12) and the support means (34) to melt the weld material. The welding head (12) and the support means (34) are manipulated relative to each other to deposit the weld material and form a carrier member of the body. The carrier member is formed to carry a projecting member. The carrier member has a first portion (52) of a first predetermined thickness and a second portion (54) of a second predetermined thickness, the second predetermined thickness being greater than the first predetermined thickness. A projecting member is provided on the first portion. The projecting may be formed by manipulating the support means (34) and the welding head (12) relative to each other to deposit the weld material on the second portion (54) of the carrier member and form the projecting member.
