turn up the heat for the inside 90's on the flanges, down a little for the butt welds. the heat for the weld connecting the two reducer pieces looks about perfect. some of the others I gaurantee you will crack, probably pretty quickly.
let a puddle form before you start moving
what wire setup are you using? some welds look like the wire is sticking a little bit or something.
if its flux core you ought to take some time to really learn how to use the stuff, its much harder than solid wire and gas.
you going turbo now?
Not that I'm ragging on you, but do a lot more test welding on scrap before welding a finished product that you're going to put into use - otherwise it's not going to last long.douglas vincent wrote:206er wrote:couple things about the welds-

I am using .030 wire, CO2....
I am getting better.
on the inside of the turbo flange, I also welded the inside and ground it down, that should help alot....
A lot of that is not accurate...scuzzy wrote:

Using pure CO2 gas, while that works, is encouraging oxide formation and will eventually trash the welds - sooner rather than later; get CO2 and Argon mix, like 80% Argon and 20% CO2
a little more expensive, but you won't get near as much splatter, the arc will be easier to control
I've also heard that a mix of 70% Argon, 28% CO2 and 2% O2 is starting to become more popular for welding steel, but I haven't used this combination myself.
Anyway, it looks like the pure CO2 is making your arc hard to control, dump it in favor of a mix and you'll have an easier time getting better
Just speaking what I know and have been taught, 555; and I thought he was using stainless, hence an argon mix would make it easier to weld.555BCTurbo wrote:A lot of that is not accurate...scuzzy wrote:

Running pure CO2 is not really a problem, apart from it just makes it more difficult to weld...as the bead is more likely to be contaminated... Your welds don't look too bad for a beginner, or for doing it on round stuff (total PITA!)
On your next bottle fill, I would suggest running 75/25 (75% argon and 25% C02)...That is what I use and the welds turn out really nice. (plus I have been welding for a few years lol)
Scuzzy, the gas you were alluding to is AB trimix...but it is a mix of Argon, Co2, and Nitrogen...and is used for welding stainless, which requires a hotter arc...so I wouldn't recommend its use on mild steel
Keep on truckin' Doug!!
