Question

Which of the following is used to visualize the heat flow and temperatures during welding?

(a) Weld decay

(b) Intergranular corrosion

(c) Tablecloth analogy

(d) Weld decay and intergranular corrosion

This question was posed to me in an online interview.

The query is from Eight Forms topic in division Eight Forms of Corrosion of Corrosion Engineering

Answer 1

Correct answer is (c) Tablecloth analogy

For explanation I would say: Tablecloth analogy of heat flow and temperatures is used during welding. To visualize a mountain like a block with the rise and fall of each stripe represents the rise and fall of temperature in a welded plate.
