Wear during digging, scraping or dredging causes removal of metal from the extractive equipment being used, which means that in time, equipment will become inefficient or indeed, scrap. This paper broadly considers the various types of wear, abrasion, impact, friction, etc., and shows applications where they take effect. Having assessed the wear problem both academically and with case histories, the paper discusses the merits and economic advantages of using welded protective coatings. A general outline of the various processes and alloys that can be used for wear facing is included. Sufficient detail is given, however, to create an awareness of the importance of selecting not only the correct alloy chemistry but the optimum technique and deposition procedure, to allow a maximum wear life to be attained. Concludes with case histories of applications where welded protective coatings has been applied to substantially increase wear life, typical applications being dredging buckets and pumps. The case histories also include cost analysis details showing that through the use of wear facing alloys and techniques not only can the wear life of critical components be extended, but considerable cost savings achieved.
