Abstract
Welding has the vast application in ship construction, automobile industries, bridge construction,
aircraftmachine 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.
