Preservation of Historic Iron and Steel in Bridges and Other Metal Structures

"Historic wrought iron and steel truss bridges that were fabricated between 1850 and 1950 are rapidly being replaced today with new concrete or steel bridges, primarily because of the lack of knowledge in the restoration of historic metals," explains Vern Mesler, Technical Careers Adjunct Faculty in welding. "We need to develop expertise in preserving the original materials by combining modern technology such as electric arc welding with historic methods like hot riveting. This grant allows us to train in those technologies."

Lansing Community College in Lansing, Michigan, is presenting a three-day workshop on March 8, 9 and 10, 2010, to introduce a wide variety of interested personnel, including State Historic Preservation officers, Department of Transportation officials, engineers, engineering students, general contractors, and historic bridge preservationists, to restoration processes of historic metals using electric arc welding, heat straightening, and hot riveting processes. Funded in part by a grant from the National Center for Preservation Technology and Training.
