A very large fillet in casting design also may cause shrinkage defects in the casting.

(a) True

(b) False

I have been asked this question in homework.

My doubt stems from Pattern Fillets in division Pattern and Pattern Making of Casting-Forming-Welding I

Correct option is (a) True

For explanation: In pattern fillets, a large fillet adds extra metal to the junction, which also may cause shrinkage problems due to the variations in the volume of casting. So the best design is to main¬tain uniform section thickness whenever possible in the casting design to keep the casting stable and strong.
