A method for continuously applying buildup material to an oil and gas tubular using low heat input welding without compromising the mechanical properties of the tubular. The method includes preparation of the surface of the oil and gas tubular and applying a consumable wire to the surface. The consumable wire may be a buildup material with a hardness that is similar to the hardness of the oil and gas tubular. The method may include removal of a defect prior to restoring wall thickness to the tubular. The method may include restoring the tubular so that a surface feature, such as taper, may be recut in a different location.

The disclosure relates to an outer dimension measurement apparatus for tubulars. The apparatus includes a first wheel and a second wheel, which may be applied to different sections of a tubular. The ratio between the outer dimensions of the different sections may be estimated based on the relationship between the rates of rotations of the first and second wheels when the tubular is rotated. The apparatus may include a tubular rotation sensor that, with either the first wheel or the second wheel, may be used to determine the outer dimension of the tubular at the point along the tubular's length when the respective wheel is applied. The methods include estimating a ratio between outer dimensions of sections of a tubular and estimating the outer dimension of the tubular at a specific point along its length using embodiments of the apparatus.

The disclosure relates to a hardbanding removal apparatus and method for use with oilfield tubulars and downhole tools. The apparatus includes a tiltable frame with support arm, a grinding wheel coupled to the support arm, and an idler wheel assembly to supply mechanical feedback to the grinding wheel through the support arm. The mechanical feedback allows the grinding wheel to remove hardbanding accurately and uniformly on tubulars that are eccentric, curved, or have eccentric hardbanding. The tiltable frame enables grinding of tapered sections of the tubular without reorienting the tubular. The method includes removing hardbanding using the apparatus.

An iron based hardfacing alloy with an undiluted (all weld material) alloy composition is substantially balanced in order to achieve an hypo-eutectic primary austenitic with secondary martensitic solidification mode. The alloy enables the deposition of substantially crack-free single layers of hardfacing onto industrial components without any post weld treatment. The hardfacing alloy is capable of withstanding abrasion of silicious earth particles when applied to industrial products, such as tool joints, stabilizers and casing and other tubulars used in oil and gas well drilling, and other industrial products.
