چکیده
Aluminothermic welding has been used to connect railway rails for over a century. This technique the advantages of flexibility, weld compactness, and simplicity. External energy is not required procedure. Exothermic heat produced by chemical reactions aluminothermic elements. To create quality welded connection, mold pouring system must provide uniform hot steel without turbulence, even dissipation or cooling, an acceptable micro macro structure free internal external faults. The design mould was constantly changing, necessitating costly industrial experimentation. As result, mould's evolving, use experimental procedures in settings. latest iteration model casting cavity improved adding hoes sand putting on both sides order more aquratly simuate transfer. Software programs are emulating conventional thermite connections save money effort timeconsuming testing. For 49E1 rail, NovaFlow & Solid CV were utilized simulate junction.

متن کاملAn Initiative Plan of the Equivalent Model for Simulation of the Welding Process
Many researchers content themselves with the 2D simulation of welding process instead of the 3D simulation, because of the time and the cost factors of the latter. In this research, the number of elements and nodes are reduced by an initiative plan (defining an equivalent model) for the simulation of welding. The welding process has been simulated by an uncoupled thermal-mechanical finite eleme...
