WMHAZ vs. weld beads

[durrerav]

Ok so I have been given a question to answer and it is as follows:

There are two pictures one of Tig cold wire and one of Tig hot wire macrographs that show the weld beads. I am asked if the number of WMHAZ = the number of weld beads minus one. I need help figuring out what this means. I can't find anything that talks about this relationship being true nor do I know how to determine whether it is true. Any help would be greatly appreciated as I have spent a lot of time searching the internet for this relationship.

Kinda hard when you don't know what you're asking for with such an odd math problem.
Whats WMHAZ?

XL83NL,
Taking a guess I would say Weld Metal Heat Affected Zone but I feel the same way as you - haven't a clue what the question is ?
Cheers,

I don't think that trying to answer an unclear question is a useful exercise.

Anyway, assuming that WMHAZ means indeed "Weld Metal Heat Affected Zone" as suggested, one could say that the number of retempered weld beads is indeed the number of beads minus one, as the HAZ of the last bead would remain untempered (by a successive bead).

Whatever that may mean.
