welding wire tensil strength?

[aametalmaster]

Mig has always been the quick fix, cheap alternative used by noobs and others to have one method of slapping lots of metal on a joint without considering the penetration effect or joint strength.

This will no doubt open a can of worms for all the Mig lovers, either flux cored or solid.

I don't agree if you are talking about MIG in general but i do if you are talking about gasless wire.
Now gas flux core is completly different and thats all our shop uses for steels up to 2" thick. I weld pressure vessels everyday with gas flux core and they are tested to 1500 psi and some of our big weldments weigh 60 tons. Just my thoughts...Bob

Lots of structural work done with innershield, they are not likely the same wire as Joe is using but some of the highest quality work is done with it.

Joe,
Never stop asking questions. Even tho in some of the threads you asked a question and got a smart a$$ comment (s) like in this thread, never stop asking. I think your doing great for a 16 year old. As you learn to weld you have to know your filler metal as well. A Lot of good would it do if you knew how to weld but, you were using the wrong filler.

Here is a good rule of thumb. Most structural steel has a 36,000 psi min. yield point and the tensile strength is 60,000/80,000 psi so most 60xx 70xx rods/wire would work,. Some cases you may have to use 110xx filler, all depends on the job/material/plans.. But anytime you are working with engineered plans you have to go with what the plans call for if you agree with it or not..

All of what i weld is mild steel with 0.30 wire of 0.35 and i try not to ask a lot of questions because it seems like all i do is take up threads but thank you

Joe,
This is why the Hobart weld talk is here. To answer questions, share ideas/projects and yes to brag a little..
So the bottom line is,,,ask away I am sure there will be someone here with the correct answer..

You are lucky too young man because you get to play with a MIG at 16. Most of us had to wait a few more years until the mig welder craze caught on and they were cheap enough to own one or two of them. I was 18 when i got my first Miller 35 and i didn't know a thing either. Come to think about it i am 54 and still don't know everything and i have run hundreds of migs...Bob

Hey there Bob,
I am not the 16 year old. But I know what you mean. I was 26/7 before I owned a mig it was a Millermatic 250 of course before that I only had them at work.. But it's nice owning your own machine..

Unlike what the twerp thinks, I had no intention of my reply being interpreted as a "smart a$$ comment". I meant exactly what I said, word for word. Read it and comprende.

Yes, it says your one... Hey how do you know I was talking about you unless you think you are one as well.. I suppose you think a person needs to learn to weld first before being able to adjust the parameters on a machine they are using?? Welding, filler and machine all goes hand in hand and all three needs to be learned at the same time, and lets not forget safety either.
I suppose you would want a weldor that knew how to weld ask you which filler to use and have you set up the machine parameters,,,,,,,Yea right.....

Flux Core Joe,

Check out the various topics at the "ESAB University" here: http://www.esabna.com/us/en/educatio...university.cfm

actually i have only 110 welders ive owned small flux core welders under 100 amps and ac buzzboxes under 100 amps yeah i will admit i am lucky in that sense.

Hi all, just my 2 cents worth, if you're using Mig for your main welding source, I wouldn't consider the aspect of tensile strength of the joint......for that to be a real factor you'd have to go to a stick weld situation.

Mig has always been the quick fix, cheap alternative used by noobs and others to have one method of slapping lots of metal on a joint without considering the penetration effect or joint strength.

This will no doubt open a can of worms for all the Mig lovers, either flux cored or solid.

If you think flux cored Mig is the way to go for all your welding needs, you do have a lot to learn.

Ian,

Thank you for your insightful comments! I work in a manufacturing "job shop" that does a couple million $ a year in sales for 100 or so different customers...including a few global companies you've all heard of. First thing tomorrow I am going to tell the company president that all those MIG welders we have are only for quick fixes and noobs.

Even though we've never had any parts rejected for poor weld penetration or joint strength, I'm sure he will run out and replace them all with stick welders. He does have a lot to learn.


@FluxCoreJoe: Keep asking questions. It's the only way you (and people like me who don't -until now- feel comfortable posting) will learn. I and many others are learning right along with you!

Short circuit MIG gets a bad rap as it is possible for an inexperienced person to deposit metal without getting good fusion; this process is generally prohibited in favor of spray arc in nuclear and military work. Most small rigs (including my 210) really can't support spray, so some people look down on them. That being said, I am sitting on several millions dollars worth of miltary spec equipment assembled with E71 wire feed.

while im here i oughta ask another question why is solid wire cheaper than flux core wire? i see 10 pound spools of flux go for alot and 10 pounds of solid wire is like 30 bucks is it because of the flux coating in flux core or is it just one of those things

Joe,
Never stop asking questions.

there is a saying, the only stupid question is the one that isn't asked. its a good saying but it is b.s.

some people like to ask questions for the sake of asking them. ever have someone ask you how long the scale was they were holding? where the heck is sundown when you need him?
