Welding of an element of a track unit and a rail section without adding any material

摘要

The stretch of rail comprises a railway switch element ( 12 ) made from high-alloy steel, in which at least one alloy element has a content equal to at least 5% by weight, and a length of rail ( 14 ) made from steel, connected to one another by a weld without deposition of metal. The length of rail ( 14 ) is formed from a medium-alloy low-carbon steel of which the carbon content is less than 0.55% by weight.
