摘要
通过对焊接工艺及焊后热处理工艺优化 ,采用摩擦焊接技术对报废抽油杆中仍有使用寿命的杆头与杆体进行了拼接 ,获得了性能达标的抽油杆。从而提高了旧杆的修复率 ,降低了采油成本。该技术可在抽油杆修复及相关行业进行推广应用。
Steel sucker rod is a kind of important equipment in oil extraction. For different reasons, there are a great quantities of sucker rods scrapped every year. Among the scrapped sucker rods, some pins and bodies still have a residual service life. These pins and bodies can be combined to make usable rods by friction welding. The welded rods must get correct heat treatment, that is quenching and high-temperature -tempering. This technique can increase the yield in the mending work.
