摘要

针对目前无磁钻具难以修复再利用的问题，通过对无磁钻具的性能特点、磨损机理及接头损伤形式分析，选择熔化极电弧堆焊技术对接头磨损失效的无磁承压钻杆进行堆焊修复，并设计了适用于无磁钻具接头磨损及偏磨修复的金属粉芯丝材，牌号为LoWare,®,-NMBU。堆焊修复试验结果表明，熔覆金属为铁基奥氏体焊态组织，磨损失效的P550承压钻杆经修复后，室温下抗拉强度平均值达到550 MPa，布氏硬度平均值达到320 HB，夏比冲击功大于120 J，磁导率小于1.01，满足无磁承压钻杆使用要求。

Abstract

In response to the current problem of difficulty in repairing and reusing non-magnetic drilling tools, by analyzing the performance characteristics, wear mechanism, and joint damage forms of non-magnetic drilling tools, melting electrode arc surfacing technology was selected to repair the non-magnetic pressure bearing drilling rods with joint wear failure. A metal powder core wire material suitable for repairing the wear and eccentric wear of non-magnetic drilling tool joints was designed, with the brand of LoWare®-NMBU. The results of the welding repair test show that the cladding metal is an iron based austenitic welded structure. After repair, the P550 pressure bearing drill pipe with wear failure has an average tensile strength of 550 MPa at room temperature, an average Brinell hardness of 320 HB, a Charpy impact energy greater than 120 J, and a magnetic permeability less than 1.01, meeting the requirements for the use of non magnetic pressure bearing drill pipes.
