A person is welding a long, steel frame in a large, industrial workshop. The frame is composed of two long, parallel beams connected by several crossbeams. The welder, wearing protective gear, is working near the center of the frame. A crane hangs overhead with chains attached to the frame, possibly used for moving the structure. The workshop is large with high ceilings, concrete floors, and many windows, and contains other metal structures, equipment, and tools. Sparks fly as the welding torch is used on the metal frame. The camera moves slowly along the frame to the right.
