REPAIR OF LOCALIZED DAMAGE IN STEEL BY HEAT STRAIGHTENING

The use of heat straightening to repair damaged steel is finding increasing applications. However, relative to the repair of localized damage, little information is available. This paper describes a methodology for heat straightening repair of typical localized damage such as bulges or buckles. The keys to a safe repair are outlined, and recommended heating patterns for typical types of localized damage, as well as methods for determining jacking forces, are shown. Experimental tests were also conducted where induced damage was repaired using various heating patterns. The data provides the basis for developing the most effective heating patterns. Use of procedures recommended here will result in a repaired member with strength properties similar to that of the original undamaged member, but with reduction in ductility.
