When it comes to forge welding you need to get the metal up to around 2100 degrees F to reach a welding temperature. Also to set your welds, you want to make sure you are keeping it flat and square.

Rotary friction welding Rotary friction is a solid-state process joining two metal objects by applying rotational motion and forging pressure to the objects. High temperatures generated by friction, transform the point of contact into a plasticized state. This area is known as the weld interface. The pressure is applied to forge a metallic bond between the atoms of the objects. The overall molecular integrity of the original objects remains intact due to the narrow heat-affected zone of this tec
