Abstract
This paper presents a review of the recent work done on annealing of dissimilar metal welded by SMAW, with the focus on improvement of microstructure and mechanical properties of specimen. Annealing is used in industry to improve the desired mechanical properties of metal such as increasing machinability, strength of material, hardness and removing stress from metal. The papers for investigation in this work were considered from 2010 to date 2021. A total of 20 research papers were chosen for our consideration after an in-depth examination of several such papers. In this paper covers the all the technical aspects which affect the quality of SMAW welded and annealed joint. Effect on all the types of joint configuration is studied. All the technical aspects of heat treated all material is covered. Effect on material quality of basic parameters like annealing temperature, heat treatment process, welding Current, welding Voltage has been studied. Finally, the area on which further more research can be carried out are identified.
