| Abstract: | Following friction welding of the tool joint and pipe of drill-rodG105, appropriate heat treatment of the friction-welded joint was carried out. The fracture toughness JIC of three point (tool joint, pipe and weld zone) bending sample was measured. The microstructure and fracture morphology of the bending sample together with the reason of toughness injury in weld zone of the joint were analyzed. |
| Keywords: | drill-rod friction welding fracture toughness toughness injury |
