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?

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?
