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.

Claim (Index 14):
The non-magnetic drill collar of  claim 9 , wherein said helical bands project outwardly of said outer peripheral surface not more than about 0.25 inch.
