Raffus,

What you want to see is, that line where the two parts meet, fully melt. That line should go away before you add filler.

In your picture, you're tied to metal above and metal below that part line, but the line is still clearly visible.

Make that line go away, and you're golden, since your bead looks great.

Same thing Steve said bead looks fine but need to fuse down in the joint make sure it joins but not bad for first one.

To make it easy, have a look at the other side of that weld, and you will see that there are just two plates standing one on the other. That is not what you want. In a good scenario, you would want to at least see some melting at the other side of the weld.

Edit: the beads look better then mine on most days ;)

When welding fillets you will not get full penetration and will not see a bead on backside. Trying to penetrate that deep is not necessary or advisable. You just need to get to root and get corect fillet size. You will prolly over heat material trying to burn all the way threw and create large HAZ weakening parent material. It is important to get in the root as the others stated above. Here is a decent link on penetration and it gets into fillet size also.

Seconded. Unless it's thin material. Like 2mm and under.
