1. A tubular comprising:
a carbon steel main body defining a flow passage, the carbon steel main body comprising an end, the carbon steel main body comprising a beveled edge at the end; and
a corrosion resistant alloy deposited along an inner surface of the carbon steel main body as a weld overlay, the corrosion resistant alloy extending from the end to a distance into the carbon steel main body, the corrosion resistant alloy comprising a metal alloy different from carbon steel; and
an impressed cathodic protection system configured to reduce galvanic corrosion between the carbon steel and the corrosion resistant cladding.
