Abstract

A pressure vessel is a closed container designed to hold gases or liquids at a pressure different from the ambient pressure. During the fabrication of pressure vessels, it has been discovered that a common problem that always occurs is at the welding joint. This problem occurs because the correct welding process is not used, and this then leads to welding defects. This project was carried out at UMW Advantech Sdn. Bhd as they are the fabricators of pressure vessels. It aims to identify the types of welding defects that occur during the welding process, to determine the type of welding inspection that should be conducted with regards to the fabrication of pressure vessels, and finally, to suggest counter measures and improvements to solve the welding defects of pressure vessels. The types of welding defects will be determined by conducting a welding inspection which consists of non destructive tests such as using a dye penetrant, magnetic particle inspection, ultrasonic testing, and radiographic testing.
