The video shows a person using a welding tool to weld a metal pipe. The tool is held by the person's hand and is applied to the pipe, causing a bright light to emit from the point of contact. The person moves the tool along the length of the pipe, creating a seam as they go. The metal pipe appears to be silver in color and has a shiny surface. The welding tool is also silver and has a cylindrical shape. The background is blurred, but it appears to be a workshop or garage setting.
