The invention of the Coldheat200 concerns a welding process for weld cladding of elastically supported or electrically insulated Vignole or grooved rails. During this process, the entire rail section that is meant to be provided with weld cladding is heated by the means of a magnetic field, generated by an induction cable that is placed on the rail.<\/p>\n\n\n\n

With the known welding methods of such rails, the occurring temperatures are considerably higher than 200\u00b0C. With the invention of the Coldheat200, a defined heat and precise temperature monitoring is being utilised. Existing materials are not damaged, defects and wear and tear of the rails can thus be eliminated and their life cycle extended – regardless of the type of system installed and even applicable to city railway tracks without any problems.<\/p>\n\n\n\n

A constant rail temperature over the entire length of the section that needs to be welded is achieved by lifting the longitudinal inductors from the rail at the start of the welding process and placing them back on the rail after the welding process is completed.<\/p>\n\n\n\n
