Abstract

A method of corrosion protecting a tube having an end portion extending into a tube receiving hole of a mud drum of a boiler and the tube produced by that method.
The end portion of the tube is provided with a corrosion resistant cladding layer which may contain chromium.
Laser cladding is used to produce the corrosion resistant cladding layer, which advantageously tapers along a length of the end portion of the tube. The tube may be swaged before or after the cladding is applied and suitable heat treatments may be performed on the bare or clad tube to develop suitable properties in the tube, the cladding, or a tube-cladding interface.
