Question 1:
Illustrate the concept of dilution specifically in fusion welding of dissimilar metals.
Question 2:
Write down the different techniques to control dilution? Discuss.
Question 3:
What do you understand by the term nugget? How the size of resistance spot weld is determined?
Question 4:
How does the spot welding diverge from roll spot welding and projection welding?
Question 5:
Illustrate the effect of fast and slow cooling on microstructure of low carbon steel weld metal?
Question 6:
Why is it that residual stress tends to become less of the problem that faster you’re capable to complete the arc welded joint?
