Abstract

See full text

This disclosure describes a method and apparatus for controlling the temperature of a welding zone for welding together pipe sections. The temperature is controlled by a flow of inert gas through the pipes. The inert gas flow is cooled and acts as a heat sink to remove heat from the weld zone thereby controlling the weld zone temperature.
