This a popular method for welding rails on site, as it can be performed in all weather conditions. This method uses a consumable electrode that melts to form a weld puddle, which is then covered by a layer of flux to protect the weld from contaminants. The resulting weld is strong, durable, and resistant to corrosion.
The void between the ends of the rail is filled with a continuous layer of fillet welds.
Permanent basic equipment: material for adjustment and preheating, a set of electrolytic copper blocks, power transformer and grinding equipment.
Consumables: specially adapted electrodes and heat insulation plates to protect the pad.
The technique requires qualified rail welders.
