Abstract
A method and apparatus is disclosed for monitoring the parameters of a rock bit which utilizes electronic sensing principles. The use of these sensing devices will provide continuous measurement of the rock bit through remote monitoring equipment. The sensing devices monitor the rock bit parameters during the electron beam welding process to assure that both the height and the gage of the rock bit remains within set tolerances while the welding process is taking place.
