Abstract
Aluminothermy welding is one of the most common processes in the railway industry. Nevertheless, this process leaves, locally, significant residual stresses that may, eventually, be responsible of the potential damaging process. These residual stresses depend highly of the preheating temperature. Failure of an efficient application of this preheating temperature is often pinpointed with the occurrence of significant internal defects and sometimes exposed cracks. In this study, we intend to highlight the correlation that bound the preheating temperature and the residual stress, and discuss the potential damaging risks.
