1.	In which run weld, in ordinary steels, the grain refinement takes place?(a) First(b) Second(c) Third(d) FourthThis question was addressed to me in an interview.This interesting question is from Metallurgy of Weld topic in section Welding and Related Processes of Casting-Forming-Welding II
Answer» Right answer is (b) Second The explanation: A MULTI run PROCESS causes a good AMOUNT of grain refinement. With every proceeding run weld, it normalizes its previous run. In ORDINARY STEELS, grain refinement takes place in the second run.
