A Brief overview on Cladding Techniques with a Reference to Weld Cladding Using Gas Metal Arc Welding

Abstract

Components working in a corrosive environment get corroded, and wear out fast.It requires frequent repairing or replacement. This results in low service life of the system, and adds to the capital cost. To overcome this problem, certain surface treatment technologies are used to improve surface properties of components working in corrosive environment. Cladding is one of the surface treatment techniques.Thermal spraying, laser-based methods, and arc welding are the techniques usually used for cladding. Among various arc welding techniques, gas metal arc welding (GMAW) process offers cost effective good quality weld clad. In this paper, a brief overview of different cladding techniques is made with a special reference to GMAW based cladding
