Conventionally, most of the welding processes were dependent on manual welding in the production of large tank for storing crude oil. In the present invention, horizontal welding is performed simultaneously on the inside and outside of the tank, and vertical welding is completed on one side by using a copper bar. By using the welding method and apparatus of the present invention, it is possible to obtain effects such as improvement of welding quality, shortening of construction time due to improvement of production efficiency, and the like. The present invention is applied to the fabrication of large tanks for crude oil storage.
