Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed and managed by the National Welding Standardization Technical Committee (SAC/TC55). This standard was drafted. Harbin Welding Research Institute Co., Ltd. The main drafters of this standard. Zhou Jun, Zhang Chunbo, Park Dong-Guang, Su Jinhua. Inertial friction welding process

1 Scope

This standard specifies the methods and requirements for inertia friction welding. This standard applies to inertial friction welding of steel, nickel and nickel alloys. Other metal materials can also be used as reference.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Inertia inerttness The inertia magnitude of the friction welding machine spindle system and the flywheel rotary motion. 3.2 Friction speed frictionratatespeed The rotational speed of the spindle during friction welding. Note. The unit is per minute (r/min). 3.3 Top forging pressure upsettingpressure The axial pressure above the frictional pressure applied to the joint contact surface after the spindle is braked. 3.4 Jeb-length The length of the weldment extending beyond the spindle clamp and the tailstock clamp (cantilever portion). 3.5 Friction time frictiontime The time interval from the contact friction of the weldment to the stop rotation of the welder spindle.
