1.	Lack of filleting of sharp corners in the casting design can cause hot spots in the casting.(a) True(b) FalseThis question was posed to me in an internship interview.This interesting question is from Pattern Fillets in section Pattern and Pattern Making of Casting-Forming-Welding I
Answer» The correct choice is (a) True Explanation: When filleting of sharp corners is not done properly, then it causes an interruption in cooling of casting that basically creates localized AREAS that solidify very slowly than the rest of the part, this result into the FORMATION of hot SPOTS in the casting, which causes VARIOUS defects in the casting.
