Exothermic welding factory price for rail industry or cable to rail(IEEE837,UL,IEC,CE,ROHs)

DW-exothermic weld powder(low temperature heat) developed by Sunlightweld can prevent the production of martenite and bainite during welding, and now is mainly used for rail flow line, rail return line, rail jumper, rail bond(continuous line), and rail cables,etc. Because of its good conductive performance, reliable connection effect, persistent vibration-resistance characteristics, it has been widely applied in the subway, light rail, trams and railway transportation.
