Question

Which of the following is not a factor for explosive welding?

(a) High relative velocity

(b) Less amount of plastics

(c) Proper orientation

(d) High pressure

I had been asked this question in unit test.

This key question is from Solid State Welding in portion Welding and Related Processes of Casting-Forming-Welding II

Answer 1

Correct option is (b) Less amount of plastics

For explanation I would say: While considering for explosive welding, the factors that one needs to understand is that, there has to be high relative velocity. There should be proper orientation and it needs to be kept under high amount of pressure.
