Orbital Welding is the type of welding when the arc of the welder will rotate up to 360 degrees. It is usually used on a pipe or something like a pipe. It was first introduced in the 1960's. It was used as a way to eliminate the contamination of water systems. It helped to decrease the spread of bacteria in the water. It was also used to purify gas and decrease the chances of a water leak. It is used for several different things like putting fittings on regulators, gauges, pressure transducers, and valves. It can also be used for welding gas panel lines, gas panels, and some of the components on a regulator or other like device.
Aerospace companies are now learning to use orbital welding in their daily welding. They use it to weld titanium fuel lines, hydraulic lines and components, and aluminum ducting. Pharmaceutical companies are also using it. They use it to weld CIP Skid, WFI Loops, Diaphragm Valves, Diaphragm Pressure Gauges, and Clean Steam Systems. There are several advantages to using orbital welding. The first advantage is that the welds can be repeated without a problem. The second advantage is the tube bore is more smooth and even. The third advantage is a smaller heat zone than any of the other types of welding. The last advantage is there is less defects in the metals like cracks. It is a harder type of welding to learn but well worth it in the long run because of its quality.
