    Patent number: 11231264
    Abstract: A caliper finger for use as part of a multi-finger caliper logging tool has a body formed substantially of a first material and a finger tip formed substantially of a second material which has greater mechanical durability than the first material. The first material and second material are fused directly together at a joint between the first material and the second material. The finger tip may comprise a plurality of successively-fused layers of the second material, which can then be machined at its outer surface after fusion of the plurality of layers. The second material may be a composite material of tungsten carbide combined with a base material in which the tungsten carbide is embedded and securely bonded to the finger.
