Laser Welding (VIDEO)
Caption
Laser welding in operation, as shown by different cameras mounted inside the new welding hot cell jointly developed by ORNL and EPRI. This experiment laser-welded an alloy called stainless steel 308 to clad a radiation-damaged 304 stainless steel surface and thereby simulate its repair. The 304 material was produced at ORNL, then irradiated at HFIR. In the future, the facility at ORNL could receive aged, irradiated material from an industry partner. At left, the bright spot is the "welding action" area. At right, a black-and-white camera shows this area from a different angle.
