Apart from their common uses in fabrication, the various welding techniques can also be used to deposit metal as a coating or surface on a component. Coatings are sometimes employed in a reclamation procedure, but when utilised on new components can allow compromises to be made in terms of cost or mechanical properties which are not possible with a single material. A wide variety of coating techniques is currently employed in industry, but in this article only those related to welding processes will be discussed.
