Any fabricators using the DcH2000 cobra

[StinkBug]

torches are handy for things other than welding i cannot imagine fabricating and repairing without the flame you cannot do it all with a tig

I fabricate for a living, and my O/A tanks have been empty for years. Just sayin.

Torches have their place, and sometimes they are the right tool for the job, which is why I own one. If we're talking about welding aluminum though, a TIG is the right tool. Now if you have a torch already, by all means do it that way. It just seems silly to me to spend a not insignificant amount of money on one tool to do a job, when there is a tool much more appropriate available.

Props to you guys who have mastered it though. That's some definite skill for sure. In no way am I bashing the process or the people doing it. I'm just looking at things from the financial standpoint, knowing what tools I use to pay my bills every month. I own both, one gets used almost daily, the other is collecting dust.

agreed a standard torch is the first welder a guy should buy if you want to fab in steel but get a tig for ally work
after all a lot guys working on sickles are doing frame work etc that requires bending steel tubes and whatnot
how the fuck do you heat and bend a piece of steel cold ?
do you not use the torch for annealing aluminum when needed when forming it and it work hardens ?
do you not use a torch to preheat heavy thick sections of aluminum ? before tig?

xb33bsa he must have some way around all that and does not need a torch for any of it

like us old school fabricators Nothing like a rosebud when you want to soften some metal up

 

[xb33bsa]

yeah ;D he proly just talks on the the metal to heat it up ;D

 

[cxman]

ahh A "Metal Whisperer"

he needs a 5 lbs abc fire extinguisher right by the door

cxman that is very kind of you! We clad the shed with concrete hardy board the inside walls will be covered also. The floor will get some form of plating. The bottles will be moved outside if we choose to weld inside. Everything between our fabrication shed and this one will get stabilized decomposed granite (better than concrete because of spills
Etc.)

good you keep yourself safe !! if you want / need the extinguisher just pm me a paypal addy lol

i dont want to step on any toes but i would like to see you have a safe fun experience

hey cxman and it's Zeke and I want to thank you very much. We will probably need it. Hahaha!!

keep him safe and teach him how to do it all!!! have fun

 

[canyoncarver]

Let us know what you think of that Cobra torch. I've been looking at them too. Nice playground upgrade!

 

[oldskool]

Sweet, can't wSit to see what y'all do with it!!!

how the fuck do you heat and bend a piece of steel cold ?

I use a tubing bender for bending tube, a sheet metal brake for bending thin stuff, and a 50ton iron worker for bending thicker plate. None of those require any heat. Take a look at my last build thread here: http://www.dotheton.com/forum/index.php?topic=47694.0

Or this link for the kind of thing I usually work on. http://www.pirate4x4.com/forum/general-4x4-discussion/833930-mishka-new-sfr-single-seater-buildup-21.html

Like I said, torches have their place. I just dont often have the need for one for the work I do. There's no reason to heat up a piece of metal just to bend it if you have the proper tools. For forming compound curves into sheetmetal sure, but heating up a piece of tubing to bend it is just hack, and isn't exactly great for preserving material strength either.

The day we got our torch we also got our new Vintage Bike magazine. This magazine is amazing! Look what was inside!

So the magazine give us the history of SIF bronze welding. We have seen it done before on Cafe Racer TV and the first thing both Zeke and I said was wow that is beautiful so we research some more and we find this http://youtu.be/ZlLV0P6uGDw

 

[Texasstar]

We know from watching Topgear that the Ariel Atom was at the top of the board once upon a time as one of the fastest production cars and we asked, "why would they use SIF bronze welding on an Ariel Atom when they could have TIG'd?" Junior told us that chromoly distorts when TIG'd and you have to hold it in a jig and let one part cool before you do another part. Then we learned that the oxy acetylene with the right technique doesn't distort the chromoly as bad. So why didn't Ariel Atom use a TIG?

 

[cxman]

the first type of welding i learned was braising it is how we used to fix everything from exhaust to body work

 

[rockcitycafe]

there's some other stuff going on with 41 series and tig, and if a post weld heat treating is done, there's no reason not to use tig, but oxy is usually used on 41's with bronze because the cool down time is a lot longer than tig and peak temperature is lower. with tig, the high heat and fast cool down causes a smaller grain size to form in the weld zone, which increases the hardness but lowers the tensile strength, leading to the common failures of 41's in weld zones. this can be avoided by heating the weld area pre and post welding with a torch, allowing the tig joint to cool down at a much slower rate
