ABSTRACT:
A high energy electron or laser beam is preferably used to assemble a drill bit. Bit segments are integrally adjoined together to form the drill bit assembly. Abutting confronting faces of the adjoining bit segments are aligned parallel to the drill bit axis and are fused together. The parallel alignment significantly simplifies the beam fusion process. The gage of the gage cutting elements of the bit segments is adjusted independently of the process involving assembly of the bit segments. Metal in a leg portion of the bit segments is fused in a zone of predetermined configuration to adjust the gage of the gage cutting elements. The zone of fused metal applies thermal contraction to the leg portion or permanently sets or relieves induced strain forces in the leg portion to permanently deflect the leg portion to a desired position at which the proper gage is obtained.
