Looking good everyone!
Little update, I think I'm going to start selling longevity welders in case anyone wants one. Gotta make some money to stay afloat. I'm also selling the lotos brand stuff too. If anyone needs anything let me know
 
Great color and a steady hand Dylan0123!
Do you do production work like that most of the time (multiple quantities)? I always thought a bench/shop welding gig would be nice (I work on the road all the time) but I am afraid repetitious work would get to me.

Thanks. I've been blessed to be able to work at shops where I have one big job that is the "default" thing to do (it’ll last a few months or even a year), and when other small jobs come in I jump on that for a day or two and do some fabrication, then go back to the production stuff. And the main or “default” job usually consists of several parts that are slightly different from each other, so I can switch around when I get bored of one thing.

So I still get to learn new things and be challenged, but I'm not constantly stressed out with new stuff that I have to figure out and I can kind of go back and relax/de-stress on a repetitive job.

It helps that I can listen to a radio or mp3 playerand just rock out and crank out parts.

Anybody ever fall asleep mid-weld? I do it probably once or twice a week, haha. If that happens it's usually because I've been sitting for too long just welding non-stop so I get up and stretch my legs for a minute, chat with a coworker, grab a snack or drink and then I'm good to go.

I have a bad habit of staying up too late working on my Talon or reading the forums!

Looking good everyone!

Do you work at a welding supply store or something? Do you have a link to some reviews on those welders? Sorry if you've already posted some, I haven't gone through the whole thread.

My intent is to review some of the machines I plan to sell. Haven't gotten my hands on one yet. (the lotos that is)
I've used a lot of longevity welders with good luck
 
They won't let me. So once I sell some and get money I will buy one and test it.
 
Gamble, we've talked in the past about it but as soon as im ready I will PM you. I've literally, no sh!t here, written out 35,000 in checks in the past 11 weeks, maybe 12 now. Lol, brand new car(wrote a check for the total), normal bills, then just hired 2 contractors for a entire roof, tear off and all, and replacing every window in my house. I know the 200sx(think thats the one i wanted) is cheap and under a grand but i gotta get some more breathing room.
Wah wah wah, sound like a baby. Anyway, i will get one and i will hit u up first! I cant wait to get into welding. These pics make me drool. So many things i can build between a TIG and the litany of new machine equipment my dad has at his shop now. Cant wait. Maybe a xmas gift to myself.
 
Very nice welding. What is the average amps that you are pulling on the TIG when you are welding like this? I tend to just use my MIG but it doesn't make as nice of a job as this! I need to learn how to use my TIG effectively :p
 
I was tacking up a v-band with no filler and liked the way it melted so I gave it a try and did the whole joint with a fusion weld:

Weld looks pretty good. The only concern about filler wire would be same materials vs different. Given the application, I wouldn't worry too much about strength. Also concave welds, unequal leg welds, etc. are called out all of the time, so a perfect weld is soley based on application.

This is true however usially there is a finish(ground, chipped, peened, machined, or the weld has something fit over/on
Top of it or a convex or concave weld. They are hardly left at that, especially if said pipe is pressureized and under vibrational load..

If it's far under the car it may be okay but if it was connected to a turbine housing where it heat cycles high temp plus vibration, plus pressure, it can and will fail.
As
For filler 308 or 316 for 304 or 316 ss if joining carbon to ss use 309, carbon/4130 chrome moly 70s-2

What concern do you have? 316L filler can be used for just about anything. 308L too if you are a little cheaper on buying filler. You can use ER70-S2 to weld two pieces of stainless together and the joint will be plenty strong, just less corrosion resistance. For something like an exhaust V-Band, you can use any filler that is a steel derivative without issue.

Exhaust is not code or x-ray weld work :p

There is more to the world than pipe welding and while this is a tubular product, it is not a pressure/oil/etc. pipe. Your local knowledge based on your pipe welding experience has lead you to an awful lot of assumptions. Unequal leg welds or concave welds serve many purposes other than what you mentioned for your industry. The weld size for his application is likely fine even if it were at the turbine housing. However, filler metal selection would be key as metallurgical properties are of a much larger concern for fatique (both thermal and mechanical) in this application. As for my experience on the issue at hand. I am a welding engineer for a tier 1 supplier that makes exhaust manifolds and hot end exhaust components for most of the OEMs.
 
I weld 16 guage and other tubing too. Not all pipe, i was just thinking exhaust manifolds.. Thats why i said sch10 and 40 he asked what amps i was pulling with welds like that.

You could technically call an exhaust system a pressure vessel you know.

Engineers...

I'm sure Code 4 knows what I'm talking about.

For the oems... So cast manifolds and machine welded and bent exhausts?hahahaha
I'm curious what you are thinkingyou would use a concave weld for though. Ive only been into pipe welding for 3 months so don't talk like ive done nothing else but pipe when you clearly have no idea what your talking about LOL.

FYI I'm just a TIG welding noob trying out different things. I wasn't claiming a perfect weld, but it was my most recent. I still need lots of practice. Normally I use a 308L filler rod.

I do pick up some good tips from this thread. :thumb:

Here's a picture of the fitment of the v-band and the finished product:

Cast exhaust manifolds are pretty much a thing of the past. Stamped and tubular manifolds are what is commonly used now. Even some new turbine housings are stamped and fabricated out of sheet metal. Castings are pretty much only found on heavy duty truck and turbo applications at this point but we robotically weld those too ;)u

As for your engineer comment, I have to laugh. I did 5 years cumulative of hands on welding curriculum at two different schools before determining what I wanted to do. I prefer to not have to work over 40hrs a week to make great money. With that said, I have no doubts that I could secure a welding position in no time if I wanted it.

I'm not going to argue with you any more about what makes a sound weld because again, that is fully dependant upon the application of the weld.

No your doing really good i was just saying if you used filler you wouldnt have the under cut and would be a stronger weld, thats all :)
 
Bah humbug. It takes a LOT to get good pricing for miller or lincoln.
 
The most recent project that Todd and I did was my turbine housing.
