An embodiment of the present disclosure is an acoustic logging tool for determining a characteristic of a ground formation during a drilling operation. The acoustic logging tool includes a transmitter section that houses a transmitter that is configured to emit an acoustic signal and a receiver section spaced from the transmitter section along an axial direction. The receiver section includes a receiver that is configured to receive at least a portion of the acoustic signal. The acoustic logging tool also includes an isolator section positioned between the transmitter section and the receiver section along the axial direction.

A downhole tool is described that includes at least three sections welded together. The downhole tool has a downhole section, an intermediate tool section mounted to the downhole section with a lower weldment, and an uphole section positioned opposite the downhole section mounted to the intermediate tool section with an upper weldment. The downhole tools as described herein include an elongate internal passage that extends from the downhole section to the uphole section through the lower weldment and the upper weldment. The elongate internal passage is sized to receive drilling fluid therethrough. Furthermore, one or more of the downhole section, the intermediate tool section, and the uphole section includes: a) at least one sensor module, b) a cavity, and c) a plurality of bores (holes). In certain embodiments, the downhole tool may be triple combo tool, an acoustic logging tool, or a directional tool, such as a steerable tool.
