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