Maximum bead width??? The two statements are contradictory
1.)"I went and looked at the WPS and it says OK"
2.)"He claims we will have to exceed the maximum bead width"
You haven't stated what code your working to, so I'll give it to you by Section IX:07
QW-253
has a change in diameter as a non-essential variable (QW-404.6)
a change in diameter > 1/4" is a supplementary essential variable. Meaning it will not typically apply unless impact testing was required and or code/spec
I don't think that last one will apply given your talking about going to to 5/32".
> Heat input under QW 409.1 is a supplementary essential variable. Again, the same clause for impact testing and or code/spec
QW 409.1
(a) Heat input [J/in. (J/mm)]
Voltage * Amperage * 60
over
Travel Speed [in./min (mm/min)]
(b) Volume of weld metal measured by
(1) an increase in bead size (width * thickness), or
(2) a decrease in length of weld bead per unit length
of electrode
Therefore, if he has a leg to stand on, it will only be in that the volume of weld metal is increased/bead size increase.
That has to be in the procedure qualification record the WPS was developed from.
But again, it's a supplementary essential variable, and only applies if impact testing was required, or the referencing code or spec makes it an essential variable.
So depending on what the PQR states as defined by referencing code/spec, he may or may not have a leg to stand on.
However;
"I don't care, I'm overriding the procedure. Y'all ain't putting slag in MY weld!"
That statement was completely out of line, and unqualified. If in fact the WPS allows it and does not conflict with the requirements of the code/spec then it shouldn't matter. As for putting slag in, I fail to see where that comes from.
I suggest being careful on this one. He sounds like he's got an attitude to me. Even if he is correct in regards to the heat imput concern listed above, thats a piss pour way of going about letting you know, and definetly a BS statement in regards to the slag.
My opinion for what it's worth,
