7018 Welding Rod Youtube. I have got the bead down with 7018 if they run the same. This rod runs completely different from the 6010 and 6011 rodsit is much smoother and easier.
Cast iron can be tricky to repair because it wants to crack from welding. It is a mild steel rod that is coated with a low-hydrogen iron-based flux compound that vaporizes to shield the molten weld bead from contamination by air and moisture. The coating put on this rod to prevent it from taking on water during its manufacturing is the reason why it takes in so much water when it is taken out of its package.
The 7018 welding electrode is very popular for its versatility and flexibility on various types of welding purposes.

But if I am doing critical work or welding that needs to comply with structural welding codes like AWS D11 I use 7018 rods that are fresh out of the can or kept in a rod oven. This rod runs completely different from the 6010 and 6011 rodsit is much smoother and easier. Make sure your electrode holders are in good shape.
