Can you repair cast iron with JB Weld?
Correspondingly, can you repair broken cast iron?
Frequently, broken cast iron parts are repaired by welding. Broken cast iron parts are not unusual, given the brittle nature of most cast iron. When castings are made, molten iron is poured into a mold and allowed to slowly cool. When this high carbon material is allowed to cool slowly, crack free castings can be made.
- Put on a dust mask, safety glasses and work gloves.
- Remove loose metal debris and rust from the pipe at the area of the hole, using a steel putty knife.
- Use the putty knife to fill the hole with cast-iron patching compound.
- Loosen and remove the nut from the bolt on a rubber-lined sleeve clamp, using a nut driver.
Similarly one may ask, what is the best glue for cast iron?
Choose a cold-weld type of steel-reinforced epoxy -- commonly known as liquid weld -- for your bonding adhesive. This type of adhesive typically includes two separate tubes: a hardener and a resin.
I am a professional tig welder and used to work at a local job shop one thing that I always hate is when someone brings in a case or any other aluminum component that they have tried to fix themselves, cast aluminum is very porous and the jb weld will get into the pores and it is almost impossible to weld.
