Re: Aluminum welding, oxide layer

Wow.

I missed some of this stuff.

So essentially the oxide layer is being sucked up by the electron flow and it's almost being ripped apart on a molecular level?

Re: Aluminum welding, oxide layer

Interesting, so how does that work?

What makes the oxide layer come off? It's obviously not magnetic so how come it just peels off when it requires so much heat to get rid of it otherwise.

Re: Aluminum welding, oxide layer

Interesting, So it's really the reversing of the current flow which breaks apart the oxide layer and opens it up to the base metal. I read it was bombardment of the ions but that's pretty general, I wanted a more in depth idea of how it worked. So the polarity reverses and that somehow rips the oxid...

Re: Lap Joints - Thick to Thin

You run the bead mainly on the thick side and just kind of dip into the shteet as you go, kine of like a Z or C or whatever you want to use, but you won't be able to run it evenly, like right in the crack like you normally would. I would TIG it if I could, I always do TIG over anything else, other t...

Re: Red hot steel

Well, it depends on a lot of things. How thick is it? Sheetmetal turns red in a hearbeat. 1/4" steel plate, not so much. Concave is not uncommon, it either means you are not adding enough filler or running way too hot and it's sinking, kind of like what aluminum does when you heat it up too muc...

Sometimes it can be difficult to notice the difference but if you get a bad batch of E3's or inconsistent results it can drive you up the wall whereas Wolfram's products won't do t...

304 stainless can have galvanic reactions to minerals in the water, and it seemed to be enhanced in water with especially low amounts of entrained oxygen.

Re: Heating up metal and hammering for better fit before we

Olivero, that makes sense. But is sheetmetal because of how much it distorts? Yes, but when doing sheetmetal you normally want a fusion weld which is done with no filler, that can only be done if the seam is tight, our rule of thumb is if you can see light through it, it won't fuse without filler, ...
