Title (EN) HYBRID DRILL BIT HAVING INCREASED SERVICE LIFE
(FR) TRÉPAN HYBRIDE DE DURÉE DE VIE ACCRUE
Abstract: front page image
(EN) A method of improving the service life of a drill bit comprises creating a weldment between load bearing portions of the drill bit where the weldment has a preselected root gap greater than about 25 mils and a preselected root face greater than about 25 mils, and where the weldment has a material property greater than the materials being joined.
(FR) L'invention concerne un procédé d'augmentation de la durée de vie d'un trépan, comprenant la création d'un ensemble soudé entre des parties porte-charge du trépan, l'ensemble soudé ayant un écartement des bords présélectionné supérieur à environ 25 millièmes de pouce et un talon présélectionné supérieur à environ 25 millièmes de pouce, et l'ensemble soudé ayant une caractéristique matériau supérieure à celle des matériaux en cours de liaison par soudage.
