  • Method of Hardbanding Drill String Components and Related Drill String Components Thereof
    Publication number: 20180339355
    Abstract: A method of applying non-magnetic semi-helical hardbanding to a non-magnetic drill collar used in well-drilling operations is disclosed herein. The method involves applying semi-helical bands using Plasma Transferred Arc (PTA), laser hardfacing, or a similar thermal-welding technique. At least one non-magnetic alloy is used to form a set of evenly spaced single blades around the circumference of the drill collar. The blades are arranged such that no single blade extends around the full circumference of the collar.
