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.
