    Re: Nuts turn WHITE when welded?

    I used stainless nuts. no coating, decent strength, don't rust, easy to find, nice and shiney when you are done brushing them. They aren't cheap, but neither is my time taking coating off.

    Re: Nuts turn WHITE when welded?

    Can't say I ever recall my nuts turning white when I welded but I do recall a few times in iffy situations where the little buggers tried to crawl back up inside me to keep themselves out of harms way.

    I am really disappointed that this thread did not go sideways, or downhill. Maybe the door was left too far open.

    Yep, a perfectly good thread gone down the tube.

    At least the OP now knows 1 reason why his nuts turned white.

    Re: Nuts turn WHITE when welded?

    I have never sweated the electroplated zinc (whatever) Now, the hot dipped stuff is another story, on pipe I'll get out the torch & heat/melt & brush it off or use a sanding disk to remove, it seems to load up grinding stones the way aluminium does.

    Yep... and they even have other shapes that make welding easier

    For regular nuts just look for the ones that say "steel" instead of "zinc-plated"
    For example 1/2-13 grade 5 would be one I commonly use. https://www.mcmaster.com/#95505a605

    From a google search I found the grade 8 tempering temperature to be 800F. Your just welded nut that's red-hot will definitely exceed this. So the fastener will be softer (and have lower yield strength) than it did originally. So there's no point in buying expensive fasteners that you're just going to ruin anyway.

    Your local DG Hardware should carry uncoated steel nuts, unless you nut then by the box load.
    At least ours does anyways.

    John, he's using a 7500 series; the 7502 which is the medium size, to be exact. Yes, the filter mount is the same as yours. The advantage of his mask over yours is mainly that it exhausts downward, keeping the face shield or welding shield from fogging up with your breath. I use the 7500 series also. I think the filters on mine right now are 2297's.

Quick pull down reseals the mask to your face and back to work. Most importantly, it fits under a welding hood.
    That's the same exact one I use, and it is a joy to use it to be honest. I use it while welding and any other chore that causes dust exposure, like chopping up bbq firewood. Sure it does get steamy in the hot temps because of humid breath, but then again all it takes is a quick rinse in the sink every now and again with a drop of nice smelling dishwashing liquid, and it's back to brand new. Just remove the filters before washing, of course.

    Anyone know if the dark gray nuts and bolts from TSC (Tractor Supply Co) have any problems being welded?

    It is. And if your it's turn white when welding, you're clenching too much.

    Re: Nuts turn WHITE when welded?

    The talk so far has assumed galvanized, uh, fasteners, but most hardware store fasteners are cadmium-plated, and I think they will smoke white as well, when very hot. And cadmium is probably worse for you than the galvanizing (although the volume of bad stuff would seem to be minor . . . ??).

    THANK you for that info, deafman!!! I've been getting the grey plastic one from my LWS, and it must be that my facial sweat or oils or whatever is toxic to that plastic because those grey masks tend to rot in a couple of years. Great tip.

    My old timer instructor said to drink butter milk after welding galvanized metal, but I don't know if the kind of milk makes a difference.

    My Dad always drank butter milk after, during or before doing a sizeable amount of welding on galvinized metal to combat the effects of the poisonous fumes. Seemed to work as he only got sick one time from the fumes 1 time in his welding career.
