Abstract
This study is conducted for the investigations of two different welding processes on mechanical as well as metallurgical properties of 63 mm thick high carbon butt welded steel. Two different types of techniques namely Submerged and Flux Cored Arc Welding which are widely used for their high quality deposition rate utilized for join thick plates for pressure vessels. These techniques provide high volume of weldment as compared to other traditional welding technique. In this study SA 516 Gr 70 steel plates with plate thickness of 63mm is utilized to investigate the properties like mechanical and metallurgical on butt weld joint with different welding process such as flux cored and submerged arc welding process. After the specimens were welded with submerged arc welding and flux cored arc welding process all samples were subjected to radiography testing, stress reliving and destructive testing; which states that the results found to be best when submerged arc welding process was used.
