1.	Which of the following parts of castings are mostly salvaged with defective cast cooling bumps?(a) Piston(b) Cylinder(c) Connecting rods(d) Gas turbine partsThe question was posed to me during an interview.My enquiry is from Salvaging Techniques topic in section Salvage of Defective Castings of Casting-Forming-Welding I
Answer» Correct option is (d) Gas turbine parts The explanation: In salvaging of gas turbine castings, parts are EXPOSED to the one side where high-temperature fluid medium has cast-in bumps on an opposite cooling surface side to increase heat transfer RATE. This MAKES uniform cooling of the casted PRODUCT to have negligible defects in the casting.
