摘要： A method of hardfacing a bit using a hardfacing sheet. The hardfacing sheet includes a hardfacing composition in a carrier material. The sheet is placed on a portion of the bit body, the sheet is heated at a designated spot using a localized heating source. At the same time, oxygen is substantially purged from the zone adjacent the designated spot. The heat debinds the carrier material from the sheet leaving the hardfacing composition. Continued heating transforms the hardfacing composition into hardfacing that is fused to the bit body.
