Abstract

Weld cladding is a process of depositing a relatively thick layer of filler material of approximately 3mm on the base metal through welding so as to develop surfaces with desired properties. Cladding is usually done to increase the corrosion resistance, wear resistance or hardness of such base metals having inferior properties. Cladding improves the service life of engineering components, and also reduces their cost. In this paper, various weld cladding technique, and effect of process parameters on clad quality including microstructure, mechanical and other cladding properties are discussed.

Keywords

Weld Cladding, Cladding, Clad Bead, Dilution, Microstructure, Corrosion Resistance.

Abstract

Presence of burr at the edge of finished workpiece often leads to difficulty in assembly operation and injury to operator necessitating incorporation of additional processes of deburring. Exit burr formation by milling usually occurs when cutter moves out of the work piece. One method for minimizing this problem is to prevent the tool from exiting the workpiece while removing material. Burr formation can also be reduced considerably by edge beveling of the workpiece. In the present work, the influence of beveling the exit edge of the workpiece on the burr formation in milling has been experimentally investigated to find out the optimum condition to control the formation of burr.
