What kind of welding rod is used for welding rail and ordinary steel?
With J506 electrode, but only in welding before welding on 60 degrees of groove; after welding, welding parts with dry lime insulation until the weldment in the lime natural cooling.
With J427 electrode, is now generally in accordance with the choice of high steel electrode types, such as manganese steel and ordinary steel, we must choose the basic electrode, with low strength steel electrode selection level, so choose 427 electrodes.Can check the specifications, such as: pressure vessel welding specifications, industrial pipe construction (welding) specifications, etc.
It can be welded with J506 and J507. However, if there is a DC welder, it is better to use J507 because weldability is better than J506. Slow cooling after welding.
1. welding electrodes for rails and ordinary steels:Dissimilar steel welds are made of materials with low strength grades. J507 electrodes can be selected with a diameter of phi 3.2 or 4, and ER50-6 welding wires shall be selected by CO2 welding.The 2. electrode (covered electrode) welding or welding filler metal in melting joint welding of the workpiece. Consists of two parts covering and core wire.
