Aluminum Welding
So someone tell me if Im retarded. I know you can weld aluminum with a TIG or MIG welder but I don't know the first thing about welding in general. I have a flux at my disposal that I am gonna start ------- so I can learn how to get a bead going and ---- but I was wondering about Alum, is it harder to weld? What is the easist way and what is the BEST way to weld it.
I was talking with a friend about it and he said it might be easier than steel to learn with. I dont know a lot about it but I thought the temps were different and Alum needed to be hotter. someone skool me. |

best = tig |
Re: Aluminum Welding
You can TIG, MIG, and Stick weld aluminium. Stick makes a ------- mess. MIG is fairly messy trying to set your machine is a hasel for someone that doesnt weld aluminium alot. TIG is the 'fastest', easiest, and best way for a newbie.

Re: Aluminum Welding
I was only going to use the flux to get used to makin a nice bead and the basics. All though I think I am going to end up flux'ing the rest of the downpipe. I dont plan to be the next master fabricator but it would be sweet to try making my own mani's and strut braces. Cool ---- to play with in the new garage you know.

Re: Aluminum Welding
I meant flux core welder. I have mig 125a and the only thing I can weld with it is steel. can't weld aluminum with it

You can weld aluminium if it has a gas setup and teflon liner in the whip. Push Pull set ups work a lot better.

Re: Aluminum Welding
correct me if im wrong but you could possibly weld aluminum with a flux mig you have to reverse the polarity and use copper wire... ive never done it but i have had some people say they have.

Re: Aluminum Welding
We had a wire feed welder setup for Aluminum at my old work. I tried using it once. The ---- would feed so fast, I couldn't adjust it, and it burnt right through the metal in a split second. I gave up.

I could make you a nozzle that slips over the end of the gun that has a tube on it for argon. Teflon liners are cheap. |

Re: Aluminum Welding
how the hell can you weld 2 peices of aluminum together with copper? and no shielding gas? you've got to be kidding... give your head a shake, you might hear some rocks rolling around up there. :S
i've used the old copper trick with mig welding steel by clamping a plate of copper to the edge of some steel to prevent the filler material from going over the sharp edge i wanted to keep. |

Re: Aluminum Welding
I know this is a year old thread but I hate opening new threads when there's something out there already. I looked at this wire:
http://cgi.ebay.com/ws/eBayISAPI.dll...MEWA:IT&ih=012 And the seller told me it was a gas-less aluminum wire. Meaning flux to me. I have a cheapy Harbor Freight welder which works fine for what I need on steel but now for my race bike I need to weld some aluminum pieces. So yes or no? |
