A method for welding rails at spaced facing frontal ends of the rails is disclosed during which welding material is supplied into a gap between said frontal ends. Part of welding said frontal ends is carried out using a laser beam for performing a laser welding process and another part of welding said frontal ends and supplying welding material is carried out by an arc welding process.
