Abstract

This basic information on welded rail steel is very much essential to ensure the quality of weld. Thermite welding is mainly used in world. The reasons why the thermite welding method is widely used are that the equipment has good mobility and total working time of that is shorter than that of the enclosed arc welding method on site. Moreover, the operating skill, which required for thermite welding, is less than that of for enclosed arc welding. In the present research work,heat treatment’ technique was used improve the mechanical properties and weldment structure. The specimens were cut in the transverse direction from As thermite welded and Heat treated Thermite Welded rails. Specimens were prepared according to AWS standard and subjected to tensile test, Impact test and hardness and their results were tabulated. Microstructural analysis was carried out with the help of SEM. Then analyze to effect of heat treatement on Mechanical properties of their thermite welded rails. Compare the mechanical and microstructural properties of thermite welded rails with heat treated thermite welded rails.. Mechanical and microstructural response of heat treated thermite welded rail is higher value as compared toAs thermite welded rail.
