Re: [MW:11479] Dilution

But there is 0.5mm difference between two readings. There can be a case where chemistry is meeting just nearer to 0.5mm but it will be not be reflected in chemistry results. S this may give deflection in original result. And one more thing I want to ask is what is the effect of base metal thickness on dilution? Is there any formula co-relating base metal thickness and dilution?

For this particular question i am suggest you to take chemical analysis for the sample at each 0.5 to 1 mm steps by chipping method. For instant result you have to take multiple points by PMI method.

Dear Maulik,

The formula which u have given is correct. But for % of element in weld metal will vary bead by bead. And also for which element shall we calculate? Because element wise laso dilution will change. So in this case what should be taken as reference?

Dear Vicky,

 

Dilution= [% of a element in base metal (by PMI/by TC)-% of a element in weld metal (by PMI/by Chemical testing)-%of a element in filler wire (got it by TC/SEC IIC)] whole divided by % of a element in base metal.

 

Then deduct product from 1 & multiply product to 100.

Dear sir,

           How to measure dilution in Electroslag Strip Cladding (ESSC)? From macrophotograph it is possible to measure are of diluted base metal and total overlay area. But how to check dilution by chemistry method? How much is percentage dilution expected in ESSC? With higher strip width does dilution changes? What will be effect of base metal thickness on dilution? What are recommended base metal thicknesses for using 60 and 90 wide strips?
