Abstract

The drill rod (10) includes a first rod section (14) and a second rod section (16) that are welded together along their mating ends (14b and 16b respectively). The mating ends are heat treated to reduce the elevated hardness that is caused by the welding. Both, the first rod section and the second rod section, each include an interior passage (15 and 17 respectively) that extends between the free end (14a and 16a respectively) to the mating end. A hardened externally threaded portion (18) on the first rod section can be threaded into the separately hardened internally threaded portion in the interior passage of a second rod section of another drill rod. The first drill rod is threaded into the other drill rod so that the surface of an annular face on the free end of the first drill rod abuts against a mating shoulder of the second drill rod.
