Not sure how to ask this question and make it understandable but here goes. My welds seem to come out a little nicer using the 2% thoriated tungsten we have at my work (using an old Syncro 250) than when I'm welding at school using 2% ceriated tungsten on a new Dynasty 350 machine at school. Is it the different tungsten, or the machine? WTF.
This may sound a little funny, I like to have some music going while walking the cup, its a rhythm thing. John
you see that GOLD weld. Thats a near perfect weld, I mean the temperature is just right, to hot turns it dark gray. thats as pretty as it gets.
It could be the machine settings, it could be the tungsten brand, but my guess is that it's the gas. Occasionally you'll get a bad bottle, or one that's not as "pure" as another, or perhaps there is an air leak.
Welding is an artform but there are some simple rules that you have to follow. Buy the best machine you can afford. All parts must be squeaky clean. Fit the joints tight, you can't weld big air gaps. Practice, practice, practice.
This is one of the most inspirational threads of all time! I love welding and I strive to learn more and this thread seriously shows some beautiful stuff to strive for! Thanks to all that have shared!
Wow, some (most) incredible welds here, i can weld alright, but as someone said before, i´m better at grinding. Does someone have any good pics of hammerwelds? i have seen a guy here in Sweden that does it so good that you didn't see the weld at all! Some pics here belong in the Friday art posts!
We used to do that back in the 80's. Not easy to do. Don't have a tig so haven't tried it in a few years.
I love the old gas welds on my 27 body... just wish someone could identify the builder or its racing application http://www.jalopyjournal.com/forum/showthread.php?t=431579
My guess is that because one is transformer (sychrowave 250) whereas the other is inverter (Dynasty 350). High frequency I think makes the difference but I'm no expert.
His welds should come out similar whether it's on an inverter or a transformer, especially if he's welding steel. The inverter can make it easier to lay some nice beads on aluminum, but you aren't gonna find anyone that can tell the difference between an inverter weld and a transformer weld. FYI the welds in post 356 were done with a Synchrowave 350, the welds in post 341 were done with a Dynasty 200.
Can i see some Oxy Acetylene Welds i know there's some guys that can put down a bead like it's tig. If theres another thread i apologize and if you could point me in that direction. I searched and came up with nothing. Thanks Frank
i teach at a welding school here in western ohio...welds look really good. taught tig now for 21years. the welds to me look like ther were done with a pulser box built into machine ,what it does is goes to a high amperage then the puddle cools and you step ahead a half puddle.this is what gives it a row of dimes look.a lot of guys do this with there foot reastat or foot pedal. makes a real destinctive ripple some guys even go back over there welds to give a nice washed out look. still loooks pretty bitchin!!!!!
The only time I use pulse now is on stainless or sheetmetal and I crank it up to around 110pps, it helps with the warping and on stainless it gives you a cleaner bead without really effecting the ripple. I don't pulse on aluminum, just dipping the rod gives you those nice freeze lines
Don't know if anyone else pointed this out, but this is most definitely NOT Aluminum MIG. It is Aluminum TIG.
Most definitely the different tungsten. 2% Thoriated is the tungsten of choice for DC welding of carbon steel and stainless. Ceriated will work well, but will lose its sharpness and ability to focus an arc much quicker than the 2% Thoriated. This is because the Ceriated has lower current carrying capability than the Thoriated. With 2% Thoriated tungsten and when the machine is properly set up ,the Dynasty 350 will outperform the old syncrowave easily.
Donny B, I only wish I could fabricate that good. These frames are for the Hurbst Brothers off road trucks. Built in Huntington Beach at their shop. Don't remember the guys name, his nick name is "Dump". As for the time fabricatioin one of these chassis I would guess 500 to 1000 man hours. Rex
I would .... & your "purge system" is a great idea. I've used bicycle tubes but will try the tin-foil trick next time on headers. Thanks. Paco
