Question

In fusion welding, welded pieces are kept together under pressure.

(a) True

(b) False

The question was posed to me during an interview for a job.

I would like to ask this question from Weldability in section Welding and Related Processes of Casting-Forming-Welding II

Answer 1

The correct answer is (b) False

To explain I would say: In fusion welding, the welded pieces are not kept under pressure, instead they are welded first and then allowed for some to cool down. It is in pressure welding, that the welded pieces are kept under pressure for some time.
