Abstract:
Tubulars are joined to each other without rotation of the tubulars. A coupling is placed between the aligned tubulars and is supported for rotation or oscillating about its longitudinal axis. The tubulars are clamped in a manner that allows a compressive force to be transmitted to the coupling as the coupling is rotated. An induction device can preheat each connection site before friction welding and/or provide heat as the connection is made and is allowed to cool down. The process can continuously create a string of casing or liner that can be run in or drilled into a wellbore.
