1. A method for making an armored cable, the method comprising:
forming a strip stock into an armor tubing;
welding a seam of the armor tubing in a welding zone;
applying an adhesive material to a welded portion of the armor tubing outside of the welding zone, wherein the adhesive material comprises a mixture of a first material and a second material and wherein applying the adhesive material to the armor tubing comprises:
introducing the first material via a first injection tube that extends through the welding zone;
introducing the second material via a second injection tube that extends through the welding zone;
mixing the first material and the second material to form the mixture; and
applying the mixture of the first material and the second material to an inner surface of the armor tubing; and
inserting at least one of a first optical fiber or a first wire into a first end of a first guide tube,
wherein:
the first guide tube extends through the welding zone;
the first guide tube protects the at least one of the first optical fiber or the first wire during the welding of the seam;
the at least one of the first optical fiber or the first wire contacts the mixture after the at least one of the first optical fiber or the first wire exits a second end of the first guide tube; and
the first guide tube is not part of the armored cable after the making of the armored cable.
