摘要
摩擦焊是一种固相热压焊接方法 ,通过机械摩擦在接触表面产生热量 ,并在载荷的作用下把 2个同种或异种金属或其他材质的工件牢固的焊接在一起。文章分析了传统实心抽油杆生产工艺的缺点和采用摩擦对焊工艺的优点。详细介绍了摩擦对焊实心抽油杆的工艺流程、焊机参数和焊接工艺参数。提高了抽油杆的质量和生产效率 。
Solid suck rod is the necessity tool in down hole. Both ends are forging and thread machining. To ensure its strength and toughness, rod string should have adequate size and better material. The most weakness part is on both ends' thread so we introduce the friction and butt-welding on solid suck rod. Rod body is 20CrMo (or 35CrMo), and the connecter using 30CrMnTi being a little less grade than rod body. Both ends are friction and butt-welded on to rod. Its mechanics strength meets API requirement after heat treatment and machining.
