SYSTEM, METHOD, AND APPARATUS FOR REACTIVE FOIL BRAZING OF CUTTER COMPONENTS FOR FIXED CUTTER BIT |
摘要 |
A reactive foil is used to assemble the components of rock bit cutters and to affix cutting elements to rock bit bodies. A small pulse of localized energy ignites the foil in a fraction of second to deliver the necessary amount of heat energy to flow solder or braze and form a strong, true metallic joint. The reaction in the foil may be activated using optical, electrical, or thermal sources.
