Abstract
A welding method includes inserting a weldable object at least partially into a through-bore formed in a generally tubular body, the tubular body having an interior flow passageway and an outer surface, and the through-bore having a borehole wall; transmitting inert gas between the weldable object and the borehole wall, the gas being transmitted through the through-bore; and welding the weldable object to the tubular body while the inert gas is being transmitted.
