Metrode Railrod description: This electrode is especially designed for the butt welding of rails with square preparation. It can also be used for welding similar cross-sections such as bars, thick plates, flanges, etc. The electrode is specially designed to enable good fusion to the side walls to take place without excessive slag interference. Weld metal has good resistance to collapse under compression by rolling loads. Applications include rails for rolling stock and crane rails in dockyards, mines, steelworks and petrochemical plants.
