Comprehensive study of laser cladding by nitinol wire

Abstract

Emerging trends in laser cladding procedure of welding by nitinol wire is finding its prominence in aviation, automotive, biomedical and thermal power plants as well as in precise repair work. Various parameters like range of applicability for laser deposition process along with new techno advent in additive manufacturing processes are making researchers to work in this domain. This paper focuses on the performance of the repaired component and economic efficiency of laser cladded welding by nitinol wire with the parameters ranging from micro to macro aspect, from low voltage to high voltage in hybrid environment procedure. Experimental analysis by Compressive and Impact test on repaired parts by Nitinol Wire through non-destructive testing machines is clearly discussed. This paper also gives briefly information regarding several methods used by additive manufacturing of different welding techniques by nitinol wire on base material. The properties of the repaired materials strength have also been discussed. Envision of this paper is to reconnoiter Additive Manufacturing, prevalently known as 3D printing. It is emerging in today’s development in manufacturing & repair techniques with advent procedure as a standard porter of the next generation industry to produce radical changes and consequently decreases the expenses in repair work & also enhances productivity. This paper also focuses on Additive technology by Laser Cladding technique which can successfully repair parts used in gas turbine engines such as vanes, stators, seals and rotors, and even geometrically complex parts such as airfoils, blisks, ducts and diffusers through different repair applications using LMD, AFM including repair of high-pressure turbine case and compressor front drum.
