Just welded with 7018 for two days straight, making ramps for the

And so I am wondering, will I benefit somehow from using MIG instead
of stick?

Mig is a lazy man's welder. Don't need to keep changing electrodes. As
far as I can tell it has no other advantage for most applications.


There being nothing wrong with that btw. Stick allows you to use a
smaller machine to weld thicker materials. An equivalent sized MIG
will be a big assed workhorse of a beast in most cases.

That being said..for normal 1/8-3/8' weldments..MIG works pretty
darned nicely and its a heck of a lot faster and easier to weld
aluminum with a proper feeder/gun than it is to weld with aluminum
electrodes

Ive got a MK products feeder and an Prince XL gun and welded up a
friends aluminum rear bumper on his racing pickup truck a hell of a
lot faster than I could have with TIG and did as pretty a weld as TIG

There is a place for all three technologies. With some over lap.

As the instructor in the welding class pointed out - with stick,
you need at most a 60% rated powered supply. That is, a powered
supply that can run for six minutes straight in a ten minute cycle
before it overheats. Which is just about the maximum time you can
weld with a stick before it is too short and needs to be replaced.
Wire feed, OTOH, can run without "time out" to replace a stick,
get some coffee, have smoke, etc.

Natcherally, Welders like stick, and managers like wirefeed. B-)

Except when they won't do the job - for various values of "do the
job". (I.e., How many units need to be welded before automating the
process pays off?)

Getting a good solid weld on a very short space is hard, but in this
case a crappy ugly weld is good enough.

But, Don, in keeping with the "haven't you just gone out to the shop to
make a somethin'" philosophy, WHY would you do a crappy job just to "get
by".

If you're already spending more of your labor than the part is worth,
make it nice.

That was why I recommended brazing. It's strong, it's easy, and it's
_pretty_. Slap a shot of rattle-can on it, and it would look like it was
forged from a single piece.

probably do it with .035" E70-S-6 and 75/25 mixed gas. Gives a nice

Steve, if "pretty" is the goal, braze it.

Easy, fast, and the nicest-looking weldment you'll get between any two
pieces of metal. Plenty strong.

Lloyd
Particularly if you drill the big peice to pretty well slip fit the
round bar in - and sweat braze it. No need for a fillet braze in the
application- particularly if all you are doing is holding the pin in
the hole. You can make a very solid and almost invisible joint.

Would that be a flux coated rod, and getting it hot enough to flow like
a solder joint? That sounds pretty nice. The hardest part would be
getting the hole drilled in the flatbar.

Steve

Simply fire up the TIG welder and use it on uncoated braze rods. You
dont even need to slag off the bubbas.

I braze a fair amount..and havent used a coated rod in at least 2 yrs

Hmm. Interesting. I'll have to get some brazing rod and try that
with my little HF tigger. I hadn't thought to braze with a TIG.

Lloyd

My philosophy is to make a part when it takes less time than trying to find an already made part. I am about ten miles from any industrial supply, so I tend to make things instead of buying. I make things strong enough for the use they will get. If you stick weld the rod to the bar with a gap and then flip it over and run another bead , you are likely to have a slag inclusion. But the part will probably last longer than I will. Would not recommend doing it if there was any stress or it was made from steel that is notch sensitive.

If you can stick weld that well, wirefeed should take you until lunch on
a bad day to learn.

But should he? Does he need to learn to use wire feed?

The reason why I am asking is that we have both a stick and mig
welder, and I historically used only stick.

As with any weldment, it depends on what you want for the finished
product. Strength? Looks? Both? MIG does have flaws, cold lap and
lack of penetration/fusion being the biggest. Unless you use FCAW, and
then, you get a lot of spatter at times. Whatever you welded with 7018,
I would trust ten times than if you had welded it with MIG, ask the guy
who had his spare tire arrangement pass him on the Interstate.

As with learning to braze small items to make intricate or small things,
it depends on what you are doing, and what you want the final outcome to
be. I have seen some of those sculptures that guys do in gas, and cut
out leaves from sheets of materials, and they are just beautiful. Yeah,
it's welding, but only slightly.

Steve
When learning to MIG weld I was aware of the ability to make good
looking but poor welds, so I learned to weld with it properly. My MIG
welds have the proper penetration and are as strong as other types of
weld using the same materials. It seems to me that learning to MIG
weld properly would be a good idea. Besides, it's fun. It is the only
method with which I can write my name legibly.

It is just a torch, but with a very high temperature. So it does not work well with ordinary brazing rod. The high temperature boils the zinc. Get some silicon bronze rod. It works really well.

If you do the welding and watch the puddle, you can know if a mig weld is good.

Like Clare said. He would trust a mig weld done by a welder that has demonstrated that he is a good welder.

But if you are not sure that you can tell that you are getting good penetration by watching the puddle, then you had better have a way of testing. I trust my mig welds especially the ones made with dual shield wire.

To me it is horses for courses. The weld needs to be adequate for the job. One could make these parts from stainless steel and tig weld them. They would look great and work well, but for this job it would be wasted time and money.

@speranza.aioe.org:

I love 7014, but to get any kind of a vee in there between the two
parts, I find it difficult to get a good solid weld in a short space. I
end up with slag inclusions, or burnthrough, or just slag. Yes, I will
probably do it with .035" E70-S-6 and 75/25 mixed gas. Gives a nice
appearance, but one must do root preparation, or get a cold lap weld.

Steve, if "pretty" is the goal, braze it.

Easy, fast, and the nicest-looking weldment you'll get between any two
pieces of metal. Plenty strong.

Lloyd

My point was that I personally find it difficult to get things "pretty"
when there is only a short run of metal, or basically a spot to weld,
doing it with a rod.

A friend of mine was an inspector on a job we were doing for Banister
(the Alaska Pipeline people) through the Atchafalaya swamp. I asked
Francis what made a good inspector. He said that the average human can
spot 90% of bad welds just on appearance. After that, it gets internal
and complicated. I have found that if a weld looks "pretty", it's most
likely sound, and done with knowledge and skill.

Although, I have said (and offended some people by saying) that I could
teach a chimpanzee to wirefeed in less than a day.

Steve
I've seen a lot of "pretty" Mig welds that were not worth the scrap
value of the wire used to create them.


Gunner nods his head and still wonders where that tire went.....

ROTFLMAO. I dared not bring that up. Thanks for the laugh. bseg

Larry...I thought you knew me better than that. I admitted it when
it happened. I didnt "not talk about it"

I knew that. Remember, I've brought it up before, too.


I thought others could learn from my ****up. And Yes..I do make an
occasional one. Like welding boat bunkers up and forgetting the ass
end of the boat was hanging from an engine hoist and not forming the
curve in the bunker....sigh

Ayup. I remember that.


I never hide from my mistakes or ****ups. Thats what pussies do.

Nor do I. If we don't learn from our mistakes, we chance making them
again. Talking about them increases acceptance and learning.


Fortunately..that one wasnt quite..quite as spectacular as the tire
episode....
Sigh

It is just a torch, but with a very high temperature. So it does not work well with ordinary brazing rod. The high temperature boils the zinc. Get some silicon bronze rod. It works really well.

Absolutely!!

Don't heat the rod, Don, heat the work.

Brazing is _soldering_. I normally don't even have the rod in the 'zone'
until the work is hot enough to flow the filler.

I have a reasonable amount of silicon bronze on hand. It works much better than brass. Especially true if you are brazing galvanized steel. Probably costs more than brass since it is almost all copper.

The only way to braze PROPERLY even with a gas torch. Heating the rod
with a gas torch can work well in combination with heating the work if
the rod is a bit too large for the job.

Yes, that 7018, if it is there, it will hold.

Bit late to the party (thread) here. I will add that i don't use MIG
where high forces are involved. its just too easy to have a nice
lookin' weld with poor penetration using MIG.



I feel exactly the same. If I have a 7018 weld, and it looks half
decent, I am completely assured that it will hold as well as anything.

i
In a situation where all welds are x-rayed I'll fully trust a wirefeed
weld. In robot welded structures, I'll pretty well trust a wirefeed
weld.
If I know for sure that a welder is an excellent welder, I'll trust a
wirefeed weld if he can show me a test cupon of the same type of weld
with proper penetration.

And what if you are operating in the real world?

Where you do not have an X ray machine?

i
Don'r need xray to check penetration on a test cupon.

the rod is a bit too large for the job.

I normally braze by heating the parts and when I think the parts are hot enough touching the rod to the work to see if the parts are hot enough to melt the rod.
You get other clues as to how hot the parts are by what the flu is doing. Ecept when tig brazing , there is no flu.

( I spilt beer on the keyboard and now I can not type the letter between w and y in the alphabet.)

When using a tig torch and silicon bronze, it is okay to let the arc touch the rod. When using fuming brass, letting the arc contact the rod, causes the zinc in the rod to vaporize and causes a mess.
