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?
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....
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.
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
