Abstract:

A welding technique for the repair of steel highway bridges is described. Recent insepction of steel bridges indicates that there are considerable fatigue cracks, which need some repair work, in bridges that have been in service more than 10 years. The demand for field welding in lieu of bolting has increased. The main problems of field weldign are welding under the influence of stresses, welding under the influence of vibration, and rewelding a weld with fatigue cracks. These problems are not common in new bridge construction. A series of laboratory and field tests on plate girder bridges has been conducted to assess the influence of these problems on the welding technique used in field repair. A recommended practice for field weld repair is proposed, and test results showing the effect of stresses, vibrations, and so forth are given. The welding technique proposed here has been successfully applied.
