Anything welding

Seriously though, I would've instinctively gone with setting it up like the butt joint on the right.
Another detail learned.
Thanks Jon.

 

A little detail that my big brother and welder of many years never bothered to tell me about. At first I would bevel the back edge and butt them. But that does not leave much weld area, so then one day the light bulb turned on.

 

Big brothers are dicks.

So my little brother says....

 

It is very natural to set up the joint on the right, my teacher taught us to use the joint on the left for everything but very thin material.
Also when welding the joint on the left it's easier to weld the inside first and then the outside, if you try to weld the outside first you're more likely (actually, very likely) to blow through.

 

Use lower heat and or whip through the middle faster. I roll past the edge a bit also so that I don't melt the edge off and have an unsightly corner after grinding.

 

With which process?
With dual shield (What we used most with that joint) that would be the best way to do that
With MIG you could do smaller/faster circles
With 7018 I would tend to run stringers instead of a weave, or at least run stringers for root and hot and then cap it with a weave.

 

MIG. Haven't stick welded in about 20 years.
Dual shield typically only used in structural? My brother's shop uses it.

 

We practiced with dual shield for the shipyards, I'm not sure where else uses dual shield because my teacher was trying to get us set up to work either for a shipyard or NASA.
I went to school down south (South Ms) but have since moved up to central Va, from the little I have looked around here (I actually don't plan on welding for a career even though I have my associates in Welding and cutting Tech) most places use MIG or Stick.

 

By dual shield you do mean gas shield with flux core wire?

 

I think for ease of topic, we should limit the discussion to MIG and basic stick welding. Introducing some of the more exotic forms of weld is good, but may only aid in confusing newer welders.

In addition, I don't really want spend time explaining different welding types that are on the rare side.

We are considered hobbyists if we are doing welding for personal projects. Once you start getting paid to weld, a whole different bunch of parameters will apply. I really want to keep the thread simple and enjoyable.

I hope this does not come off as harsh, but we need to be realistic in our goals to weld for ourselves.

I've said before, MIG welding is the type of welding that is most user friendly for the home hobbyist welder. I can do many different types of welding, but choose to become proficient at MIG welding. If someone is asking for information on some of the more exotic welding types, you can color me gone.

 

Wow. Ok....

 

Yeah, I knew it was over the top, I don't know when to stop typing sometimes.

 

Yes, in school we welded with .045 flux core with 75/25 mix.
As Kirk stated dual shield isn't used for garage/hobby welders, however I like dual shield because of how smooth it welds and how well it flows.

 

Never tried it myself. I assume I could throw some .035 flux core on my machine and try it.

 

That is why I no longer answer stupid questions that have been answered times innumerable on this forum. Apparently I get a bit of an attitude.

 

Wait. Hold the presses!

I thought flux-core was for noobs like me because it required no gas. And that MIG was a step up. Similar welding theory for both?

 

Negative, Standard fluxcore wire won't behave with shielding gas, FCAW-S (self shielding) runs straight polarity whereas FCAW-G (dual shield) runs reverse polarity.

Gotcha. Had no clue the polarity was different
