摘要
探讨了地质钻杆用DZ60钢钻杆管体与40Cr钢钻杆接头的摩擦焊接性,并与采用热墩粗工艺生产的钻杆管体力学性能进行了对比。结果表明,摩擦焊接的地质钻杆具有良好的综合力学性能。
Friction weldability of geological drill rod to adopt DZ60 steel of drill rod pipe and 40Cr steel of drill rod joint have been explored. Mechanical properties of this friction welding drill rod and drill rod pipe adopted by hot upset forging technology have been compared. The results showed that there are good comprehensive mechanical properties in the geological drill rod welded by friction welding.
