Analysis the Effect of Welding Current Using Radiography Test, Penetrant Test, and Magnetic Test Methods on Corrosion Rate of Pressure Vessel ASTM A 36 Materials

A pressure vessel that functions to store liquid or gas which is often used in the oil and gas industry and has a pressure difference on the inside from the outside. Pressure vessels have several important components. These components are interconnected using a welding process. The welding process is carried out by many variables that determine the result of the welding, one of which is the strong current. The welding results are not spared by the existence of errors in the welding process. These errors are in the form of welding defects which can interfere with the quality or quality of the welding results. To be able to detect a defect and to be able to determine the quality from the welding results, a non-destructive testing process is carried out. The non-destructive test used in my final project is using the magnetic test method, penetrant test, and radiography test. this can find out the type of defects that occur in the pressure vessel and can determine the best type of Non-Destructive Test method for detecting a defect in the welding results carried out in the pressure vessel manufacturing process. welding defects that occur. In addition, additional tests will be carried out in the form of corrosion rate testing using the weight loss method with variations in welding currents which will later obtain data on the relationship between strong currents and the corrosion rate that occurs.
