Do we have any welders in the house?? I was just wondering cause I am currently going to school to become one...

I wouldnt consider myself a welder but i can weld I do Tig/Mig weld every day at work Fiddled with alluminum a few times

....I weld bridges..........

...........well, before I got promoted I did............

........but I still weld when the need arises........

Thats awesome... I wanna go down to Virgina after I get out of school and weld ships or submarines. Something like that I hope!

Under water welding I always wanted to do that

aluminum welding is called brazing

Yea underwater welding is awesome. I hope one day I could get into that field. There are 2 types of underwater welding, one just like whats seen in the video above, and one where they put a capsule under the water like around a pipe, then you get into it, and you are in a dry enviroment, and you would weld just like if you were on land in a shop. I think both are awesome!!

Are you sure?

Geez I am confused, I thought brazing was different than welding.

My wire feed welder and that bottle of gas thingy, weld it all the time.

Maybe that's why I have trouble with that dang spool thingy, from time to time.

I can't believe LINCOLN ELECTRIC would sell me a dang machine, that is supposed to weld Aluminum, when I should be using my torch and brazing it.

Really ticked me off, when they made me buy those valves and that bottle thingy too!!!

BT, do you think they will give my money back?

I am pretty sure brazing is different, thats when you use oxgen, and acetelyne or propylene, or whatever gas you choose to ahha and you use brazing rod. Gotta get those temperatures above 840 degrees to do any brazing. Dont forget your flux!

Thanks for clarifying that, I thought I was loosing it for a sec there.LMAO

That Blazetoy guy usually knows his stuff, so I was worried. JK

Hey thats why I am going to school ahha. Dont get me wrong blazetoy bazing can be used to weld multiple metals together. So ya you can braze aluminum.

Yes but welding aluminum is not called brazing.

There will be tests in school grasshopper.

LOLOL !!!!!! Lets see now, Brazing.... HMMMMMMMMM Maybe you would use Braz.......OH WAIT, Maybe Brass, Yeah that's it Brass for brazing.

 

[gverb1219]

Brazing is done with any type of alloy, be it brass, aluminum, silver, bronze, etc......

Brazing is done by Oxy/Acyt torches whereas the filler material and the object reach the same temp or melting point and the liquids join to become one....

Brazing is not recommended for structural work as it does not hold up to stresses very well...

.....normally used in ornamental works or areas where you may need to join 2 dissimilarmetals.

For joining steel components, it is known as Braze Welding[/B], but it still is done with Oxy/Acyt torches.

For WELDING, you would use either stick welding or wire feed,.........Tig or Mig...

Tig (Gas Tungsten Arc Welding) welding is mainly used for stronger welding of thinner materials...........stainless steel, aluminum, and other alloys...

.it uses sticks or lengths of rods similar to brazing, but at much higher temps.....with a hand pistol that controlls the electric arc........all controlled by a foot pedal..........

Mig (Gas Metal Arc Welding)welding is a welding process auto fed by wire spools, which are the electrodes. Mig welding is very versatile and can be used for most any metals from the thinnest auto body panels to the thickest steels..........

Wanna know about cast iron welding..........

While lots of people say you can weld cast iron, you really shouldn't weld it with an arc welder......

The prefered method for repairing cast iron is to pre-heat it to about 1,000 to 1,300 degrees, and by doing so, you would braze or fuse the metal together.

We use Temperature Indicating Sticks at work of varing degrees.

You heat the cast iron up until the stick melts when you stroke it across the metal..............only then is the cast rady to be brazed..........

And what about Peening ?? Post cooling ??

Thats not correct when you weld aluminum the best method used is Heliarc (aka TIG) you have a better finish than MIG. And then its Mig I work with guys that have 40 years plus of welding all kinds of metal and they say for Aluminum the way to go is Heliarc. Anyone can MIG weld but its takes someone who knows the art of welding to master TIG welding. Brazing This is similar to soldering in that the added material is not the same as the base material a flux is required.
