| Abstract | ||
| Steels of high carbon content,. in general, have high strength, that makes them needed in many engineering applications. However, the repair of components made of such steels through maintenance by welding presents a major problem. Therefore. in the present investigation a trial is made to find out a way to facilitate the welding or such high carbon, high strength steel with the objective to improve its mechanical properties. Preheating to different temperatures was carried out on different carbon content steels before butt weld joints were made. The joints were subjected to tension and corrosion tests. The results showed that there.is a relation between the preheating temperature and the carbon content of the steel of interest.~he~ showed that preheating in the range of 100-150°C improved the tensile strength of the tested steel of carbon content of 0.6, 0.9 and 1.55 wt.%.,Little improvement of ductility has been noted. Also, the results showed that, little effect for preheat on the comosion resistance. | ||
