Some one told me they had heard from a fellow smith that white out could be used as a resist on the inside walls of mild steel cans; used in canister welding. Any one try this technique or no of another resist that is used on mild steel canisters?

Thanks Fred
 
Still looking for an answer.:confused:

I hope this is true. We have a good collection of mild tubing and box steel.:eek::cool:
 
I've read that several smiths are using Stainless HT foil to line the mild steel box and the foil prevents sticking so the box and foil peel right off with a chisel later

Is that what you want to use it for ?

Foil is ok with mild steel and stainless itself works; the white out would be the cheapest route if it works.

Thanks you, Fred
 
I've seen a jewellery supply of "Yellow Ochre" used in Mokume Gane as a heat protective non stick coating on the pressure plates.

I've also seen white out used as an easily obtainable substitute for that.


I'm not sure white out would be that cheap, unless you find how to buy it by the quart instead of the ounce.

I'm not sure of the source I saw for using White out

The obvious, is to purchase a small amount and try it. I'll post the results.

Hey Fred.
Back when I welded for a living we had some anti-spatter that contained calcium carbonate. It did a good job of preventing weld spatter from sticking to the work. I think it was mainly lime, we mixes with water and then painted on or dipped depending on the size of the part.

I realize welding in a can is a bit different but there might be a product from the weld supply that would do what you need.

There are other anti spatters that are solvent based also.
just a thought..
 
I have used the yelloe ocher powder several times. They suggested to mix it with water, paint it on and then it was ready to protect. I got into using alcohol with it. It will dry as a simple powder coating that bwhen barely touched it will come off.
Try a test coat of white out on a piece of steel , Fred. Frrank
 
I know of several mokume makers who use white out as a resist between the steel clamp block
and the mokume. One of them is Delbert Ealy.

Thanks Dan, I'll give Delbert a call and see what he's up to with that.
 
Any oxide will work as an anti-welding agent. The higher the melting point and the more reactive it is with oxygen, the better. Magnesium oxide, titanium dioxide, iron oxide ( yellow ochre), and a host of others all will prevent welding. I have heard of people using white spray paint ( TiO2). White-out seems pricey for more than a one time thing.

Get a pound of titanium dioxide from ebay, mix it with a quart of the cheapest white paint you can find, plus a pint of thinner, and make your own white-out. total cost will be about $10
 
Thanks for the recipe, it sounds worthwhile.

Just the other day I was researching making SS damascus. In one of the threads I was reading, the poster stated that he would get some red clay from his yard, mix some with water and make a slurry with it. Pour it into his box, coat the inside then dump out the rest and wiat till it was dry. Maybe do the same with a little satinite?

Red clay is fine silica sand and red oxide...or ochre.
Satanite is a silica, which is an oxide. Both will work well. All that is required is a barrier that will not break down or bond at 2500F.
Pottery slip would also be a great release/resist.
