| Structural wrought iron was used extensively in the second half of the 19th Century to construct bridges and buildings throughout the United States. Many of these wrought iron structures are still in use today, and are in need of repair and renovation. While many methods are used for the repair of these structures, there is no published, pre-qualified welding procedure using modern welding technology for the repair of historic structural wrought iron. This thesis investigates the ability of a specific welding procedure, using modern welding technology, to repair structural wrought iron samples which were removed from a historic bridge. Additionally, the physical properties of this historic structural wrought iron were tested and documented, in an effort to increase the data available to engineers who are tasked to work with this unique structural metal. |
