Abstract

Welded downhole tools and methods are provided. The downhole tool is deployable into a wellbore penetrating a subterranean formation. The downhole tool includes a first downhole component having a first mating feature on at least one end thereof and at least one second downhole component weldably connectable to the end of the first downhole component. The second downhole component has a second mating feature on an end thereof. The first and second mating features include at least one raised ridge for concentric self-alignment along a common axis with the other of the first and second mating features whereby, upon frictional engagement of the end of the first downhole component with the end of the second component under heat and pressure, a welded connection is formed therebetween.
