GAS WELDS - post pics of your work!

To learn the art, go back and read post 15. Then read it again. Practice, practice, practice. The thing I like about gas welding is, it happens slower and can be controlled easier. For hammer welding; you need the hammer and dolly in your lap, and a stand to hang the still burning torch, with the tip pointing away from the hose. Again, practice. I like gas welding exhaust. I have made several complete exhaust systems from engine to bumper with store bought mandrel bends and straights.

 

That is weird.......I was thinking today about the best way to recommend someone learn hammer welding and I remembered the first real success I had learning was when I ran my pieces thru a slip roll then welded them and planished them on an anvil with a curved point. Then I worked my way to flatter material.
spooky!

 

One of my dads buddys prefers to do all his gas welding with metal coat hangers and it is excellent work, he's a perfectionist. Anyone else do this?

 

Exhaust is awesome! I've only done one set of lakes hedders, and some 3" dumps for my stude so far.
A torch stand is a must! It should be tall enough not to singe the Pug! It took days to get the smell out of the shop!
I really like planishing stands for hammer welding. Most are cheap or free stuff I scrounged. My wife bought the cobblers stand for me for xmas. She rocks

 

great thread. thanks fellas..

 

You guys are artists. Just need to get a wrench for the acetylene and some rod. What's a good rod for steel? Is it the same rod that would be used for arc stick welding?

 

I use 1/16" mild steel. It's actually TIG rod. It's not art. It's craft. Artist ar born... craftsmen have to work for it!

 

Most good welders I know avoid coat hangers. They may have been made with a good grade of steel "back in the day", but I'm sure today, they are very low grade steel with lots of impurities in them (made in China?)
Do you really want to contaminate your metal with ****py steel?

 

Yeah, inna pinch, you can use hangers, but I wouldn't make a regular pratice of it !
A whyle ago back I was rebuilding a couple of thirty-two fenders, and needed to weld up some splits, at four in the afternoor on a sunday, I couldn't find any gas rod in my shop and spotted a roll of rebar ti wire, you know the oily, dirty black chit? I cut a couple of three foot pieces off, and wiped them with acetone as best as I could. The tacks I made came out clean and melted like ****er without any dirty cruddies in the molten welding pool. I figgered, what the hay, and welded out the splits and patches. The beads planished out very nicesly, and with a couple swipes of the file you couldn't tell them from the parent metal
Inna pinch I've cut thin strips from s**** fenders like from the vehicle your rebuilding, say 1/16 X 3' and ground to bare metal on both sides- works well, but ES 70 is still your best bet!

For good rod, head to the place you will buy your gas and ask them for the rod you need. Tell them you are new and what you plan on welding. Done buy a lot, keep it dry and keep it clean. Buy a piece or three of coated brazing rod too. A good braze is rated at 60,000 pounds. A fair gas weld is rated the same. When you get really good at steel and braze, learn about gas welding cast iron.

 

Tried gas welding for the first time on friday in the cl*** I'm taking. I really like it. I'm already wanting to buy a setup. This was the top angle on a little house I was building out of welding coupons. That was the mini-project for the night.

 

Nice job! It's kinda Zen like isn't it? It's one of my very favorite part's of the build process.

 

I use mostly coat hangers for gas welding. They have clear Laquer on them so heat up in the flame and clean off the residue with steel wool. I have been doing it for 50 years and it works great on exhaust tubing and sheet metal.

 

Thanks! Ya, it is. I started learning to weld with tig, now trying mig, stick and oxy fuel. I really like tig and gas because you can go slower.

 

"It's kinda Zen like isn't it?"
When I first got my little O/A unit I burned up the tanks quickly just standing at the vise burning rod! I'm not as good as you guys, but I'm better with my O/A than I am with my MIG, and sure enough better than the old stick welder I learned on.
Funny part is I'm left handed, and when people look at my welds the first thing they say is "they're going the wrong way!"
I'm subscribing! I've already learned to turn down my O2 pressure to help make the puddle easier to work! Looking forward to everyone's input. Thanks!

 

Everyone should learn to gas weld first, so much easier to see and understand. Bob

 

I*f you talk to guys that do a lot of Aluminum panel work a lot of them prefer Oxy/Acet welding for hammer and dolly work the gas welds are softer and more flexible than either mig or tig. You do need special welding lens for aluminum not your standard green lens. I stumbled onto a purple lens that I found out from an old timer was for aluminum work, I got it in a box of "Junk" at an auction. I did learn to gas weld aluminum and could run nice beads but haven't done it in years now. As for what can be "Gas" welded at one time or another everything was gas welded. I visited Stroudsberg RR Museum last summer and saw broken drive rods on what I think was huge steam engines that had been clearly broken and welded with gas welds lots of other areas also. We're talking 3 inch or thicker materials the "thin stuff" is over an inch.

 

heres a few pics of the rear cab corners of my F-! .New sections gas **** welded in and file finished. PB

 

Subscribing, this is a great thread. Im going to practice this before I start my 36 Sedan build. I am sure it will come in handy for the sheet metal work. Thanks

 

Practice is critical. Too many guys try to learn how to weld on their car. Get a good understanding of the effects of heat on the metal. Get a good file.

 

I am goin to have to take some pics,We still use gas to do 3/4 inch gas line services up north here....I did weld to my headers up with torch since they were run I chose torch because oil/gas in tubes over tig.Two p***...fused them up and put a hat on them...

 

Damn Fleet-master that looks great! Looks like I've got some learning to do!

 

thanks 28Tudor ! I'll try and post up a couple pictures that may help for learners later tonight...Its mid morning here at mo

 

I have recently gotten an o/a setup and with the information online and videos full of information I have been able to weld a patch piece into my bedside of my truck, and I welded up a crack on the other side. I am proud of the accomplishment of attempting to try it, but as stated practice, practice, practice. And since no one is lining up at my door I will practice on my own stuff until I get it right.

 

And since you guys like pictures

 

sorry but I think ill decline showing pics of my gas welds. ive been welding for around 40 yrs. my gas welds look like turkey ****. always have always will. lots better with mig and tig but aint noway in hell im showing anyone my gas welds...lol

 

right! I dont know how they teach now, but we couldnt move on to any other type of welding until we could gas weld first.
