Pressure vessels and piping constitute the maximum percentage of static equipment in any oil and gas facility. Separators, drums, desalters, columns, reactors and heat exchangers are only a few examples of the numerous types of pressure vessels used in the hydrocarbon industry. The design of welds is critical to any pressure vessel fabrication process. As part of weld joint fit-up and proper alignment prior to welding, tack welding is done between the pressure vessel components (such as the shell, dish ends and nozzles) prior to the initiation of the actual welding process. This is a common practice during pressure vessel fabrication and repair. During the fabrication process and any repair
