"The purpose of this study is report the fabrication of the spot welder. Spot welders are used for welding between metallic samples. We research the electron emitters. Then we need a spot welder for making tungsten electron emitters. A spot welder is expensive. Therefore we decided to make the machine for ourselves. For designing the spot welder, we use conventional electronic devices. The spot welder was able to weld tungsten samples as a result. Therefore we are going to try to research the electron emitters using the spot welder for making the samples."
