Thermit welding is widely used for joining railway tracks. It involves a chemical reaction (thermite reaction) between
aluminum powder and
iron oxide, which generates intense heat to melt and fuse the rail ends.
Key Points:
· It is a type of fusion welding.
· The reaction produces molten iron that joins the rails.
· TIG, CO₂, and SAW are not suitable for large-scale rail welding.
