A pressure vessel model developed via submerged arc welding

In this paper a pressure vessel model is developed via Submerged Arc Welding (SAW) method. Storage vessels that are design for pressures of about 50kpa are regulated. The transportable gas container are not pressure vessels in themselves, however, the process heating equipment of steam or hot water generation are defined as pressure vessels. The manufacturing of these vessels follow certain health and safety regulations such as ISO9001:2015. Accordingly, a pressure vessel is designed to be fabricated using these safety standards. In this research the welding current, voltages, and travel speed significantly affects the tensile strength and the hardness. The first factor welding current of about 260, 270 and 280 amperes were used for the investigation. The results show high density and increased material tensile strength and hardness. The welding using SAW was done safely and each condition was tested a total of three times by using full factories design. All the components parts aligned properly, there was no misalignment that could be observed.
