Study and analysis of Electric arc welding in air and underwater by using the mild steel to check the skill of ultimate tensile strength

Abstract

The paper describes the behavior and fundamental process of underwater welding. Any repair method underwater will require the use of underwater welding. This paper presents sate of the art of underwater welding to assist the development in this field. Commercially available modern electrodes and flux cored wires of special type ensure good quality of welded joints. In this  paper we are showing the hardness of air welding with compare with underwater welding. We also shows the systematic diagrams which are suitable to indicated the all process.
