Abstract

A method includes removing a section of electrical insulation proximate an end of a tubing-encased conductor (TEC) to form an end of electrical insulation that is axially recessed relative to the end of the TEC. The method includes welding an end member to an outer surface of the outer tube at a weld joint that is axially between the end of the TEC and the end of the electrical insulation to protect the electrical insulation from heating damage from welding. The method includes replacing the section of electrical insulation proximate the end of the TEC by inserting a spacer into the end of the TEC between the outer tube and the electrical conductor after welding the end member to the outer surface of the TEC. A tool can be electrically connected to the electrical conductor and the tool can be welded to the end member.
