Description
Summary:Welding has the vast application in ship construction, automobile industries, bridge construction, aircraft machine frames, structural design etc. Safety and durability of every construction mostly depends on the accuracy of welding joint. Therefore, it is very important to join metals without any defect. This research is done to ensure the impression of current and voltage on porosity found inside the welding joint and other defects. This is done to improve the quality of material. This research is carried out for single V-groove electric arc welding and inspected by Phased Array Ultrasonic Testing (PAUT) method. The investigation of this work is to make a comparison based on defects and porosity among the welding samples for different voltage and current.
