[MW:2496] Re: Copper sulphate

While installing new nozzle, old will be removed for which weld needs to be removed.

Copper sulphate will help in justifying that all the clad material is removed & we have reached the C.S surface.

After the application of copper sulphate if the color changes to rusty sort this indicates the surface is C.S.

This is very important from welding point of view.
