自从30年代开始在油井钻探采用焊接接头钻杆以来，近40年时间内有了不少改进。例如由闪光焊（FLASH WELD）进而发展有惯性焊（INERTIA WELD）、摩擦焊（FRICTION WELD）和韧性焊（TUFFWELD）——对焊缝进行调质处理。
Since the beginning of the 30s, the use of welded joint drill pipe in oil well drilling has taken a lot of improvement over the past 40 years. For example, INERTIA WELD, FRICTION WELD and TUFFWELD are further developed by FLASH WELD - the weld is tempered.
