چکیده مقاله
In this research, the main purpose of the study was to weld two branches of rails with a length of 36 meters and turn them into a branch of rails with a length of 72 meters Common methods for rail welding, including flash butt, naro gap welding, and termite welding, should be reviewed and open post welding tests evaluated and described The results showed that the CE carbon for the produced rails in Isfahan Steel is approximately equal to 0 887 which was very high and will face the problems of rail welding such as high hardness and cracking Due to the high hardness and high amount of carbon in this alloy, the highest hardness is observed in welding, which can be considered due to the fineness of the grains and higher cooling rate, as well as the high heat received inlet Dueto the heat, the hardness decreased a little, which was due to the resulting grains due to the decrease in the amount of weather during Research has shown that ultrasonic welding test is the best method for inspecting rail welds and it is possible to check defects with a normal 70 degree probe The results also showed that loading rails with a length of 72 meters can be performed after welding with the current conditions
