Doesn't look like you have much of a weld gap; without one, you'll warp the metal easier.
You should also clean off the undercoating near your weld; otherwise when it burns it will contaminate it.
I use a roloc #30 or #40 sanding wheel on a small 90° angle grinder - much less aggressive and more controllable than the angle grinder. For final cleanup I use a #50

What he said and hold your stick out to a minimum. You want the arc to be small, cool and a small puddle. Yet you do need to see the weld from the backside, no more seam.
I weld with as small a stick out as I can. I have to look from the side because the gas nozzle blocks my view I'm so close.
Don't always believe in the gas flow setting nor the position of the nozzle on the threads. You can grind the nozzle at an angle too, if that helps.
Weld in 1/2' segments and move way far way for you next weld while the previous area cools. Snip off your wire before you start each time. Wire brush the previous weld before starting your next segment. Start your puddle in the old weld, not next to it.
Go slow and stay cool is my weld motto.
