Welding

[DataXUnknown]

I was wondering if there is a huge difference or not between an electric welder and a normal welder that uses gas. I'm looking to weld my BOV flange and I'm a newbie to welding, my friend has an electric welder but he says it probably wouldn't work for that.

I'm not too sure how much a shop charges to weld it on, because the guy just told me $75 an hour (don't really think it would take an hour).

Oh and the pipe is black, I don't think it's aluminum but I don't know what other kind of pipe it would be.

Stick a magnet to it and see if it sticks. If so its metal and you can weld it. The best would be TIG for that application. But yes a Gas welder will give you a stronger weld and it looks alot better b/c you don't have all the splatters.

If its aluminum then you need to take it to somone who has an aluminum TIG welder to fix it for you. You can't weld aluminum with the same welder as steel unless its a Mig and it has the aluminum gun with its own seperate spool.

all welders are electric.
Mig/Tig are both gas shielded. It is possible to use a Mig without gas, but the weld will turn out like crap, especially if you arent a great welder to begin with and even if you are.. it uses flux to shield the molten metal, so it wont look good or penetrate very well. An Arc welder (stick) is not gas shielded and is more for farm equipment or structural stuff (large pieces of steel)

If the metal you are trying to weld isnt steel, then you'll need alum wire setup. Also Alum is more difficult to weld, so for a novice it will be very difficult.

as a side note, tubing is one of the harder things to weld successfully (especially for a novice) and due to the heat on the part you are going to weld, I would highly suggest taking it to a reputable professional welding shop. Welding is fusing the two parts together, alot of people approach it like "metal glue" which it is most definately not.

take it to a smog shop, should be like 10 bucks

Actually the majority (if not all) of flux cored welders use a CO2 sheilding gas. I"m not talking about those shitty little 115v flux cored welders you can buy at a local car parts store. I'm talkin about a real flux cored welder. Which, by the way, has incredible penetration. And can look very appealing.

And, MIG, cannot weld withou a sheildingt gas. Real flux core can't even weld without a sheilding gas.
For those who think flux core and MIG are the same. They are definately not.

Thank you for the help guys, this information will come in handy when I get into making a cage and maybe welding a differential. I'm going to try the weld on sunday for my BOV. This is going to be interesting haha.

def take it to a shop if you dont know how to weld...if you were to do it yourself that could be some bad news.
id just get it done the right way first..but thats just me

GOOD LUCK either way

I guess I wasnt entirely clear as I was giving general info on the topic.
Yes, MIG uses a shielding gas. Argon/co2 mix usually.. though Co2 can be used by itself.

You can weld with a MIG machine without gas, I've done it. You put the flux core wire in it and change the gun/hose/tip/wheel.
Not all welders are capable of this, and obviously a normal Mig machine without the conversion wont work right.

Not sure what you mean by "real flux core"

In any case, to the poster: Take it to a pro welding shop... or practice on other non important stuff..

stick welding is shielded... just in a different way. When the stick is melting the coating evaporates and that is the shielding gas

Yeah I know.
Next time I post any info, I'll be sure to cover each and every possible detail to prevent confusion.

ok sounds good. haha. just messin man. Its just for whoever is looking at it. i was just helpin ya out

[just1pepsi]

oh, no worries. lol

^A "real flux core" uses a C02 sheilding as. Unless it's one of those cheap ass 115v welders you can buy at a auto parts store.
I have NEVER seen an industrial flux core welder that doesn't use a C02 sheilding gas. IT is almost a given it will use it. Especially for structural welding....
