Question:

506 welding rod whether welding pig iron?

506 welding rod whether welding pig iron?

Answer:

Type J506 electrode, belonging to the low hydrogen basic electrode, the weld metal with better crack resistance, DC arc welder used reverse polarity (wire clamp electrode connected to the positive electrode holder, welding stress +) can not cast iron material.
Pig iron is the bulk of iron ore that has been cast after the first smelting of iron ore. Smelting again, removing impurities, adding alloys, etc., is cast iron. Pig iron belongs to the semi-finished material of cast iron.
No welding rod can weld pig iron. They include grade J506, model E5016, low potassium hydrogen type leather, low alloy high strength structural steel welding rod.
