Can a threaded joint be welded?
yes ,we can weld this. welding is the process of joining two materials .we can join this by spot welding or by arc welding.
What is temperature embrittlement?
If a loss of ductility caused because of temperature, it will be temperature embrittlement. When welding, if cooling rate not controlled, it will leads to faster cooling(Martensitic zone) and will produce brittle structure which normally defined as temperature embritttlement.
What is a structure that uses melted joints like soldering and welding?

Can weldding cast iron?
in order to do welding of CI first it is pre-heated and then welding is done on it and after this very slow cooling is done by putting it in pit and then covering with mud due to this CI retains its ductility
What is the advantages of postheating during welding?
Basically to prevent the weld and metal from cooling down too quickly which can damage or destroy it.
Why silicon dioxide is a suitable for welding blankets?
because it has many strong covalent bonds in a lattice structure (such as diamond)
How prepare welding procedure specification?
