Historically, hardbanding wires that exhibited improved tool joint protection did not have very good compatibility with other hardbanding wires. The DRILL-GUARD series offers superior protection and includes hardbanding wires with excellent welder appeal and a high level of compatibility with competitive hardbanding products.
An inspection of the previous worn hardbands and if required the approved repair(s) prior to re-application of hardbanding is inherently part of the hardbanding process.
