Your beads look cold, just sitting on the plate with little or no fusion, looking at the pointed shape of the ripples you are moving too fast, and /or the torch angle is too low,

i think i was moving to fast but i did a test piece which i destruction tested and also cut n acid dipped,penetration was fine just trying different visual finishes

whats prefered in mig welding, the flat bead or the ripple effect..the only people who look at welds are welders so what the desired mig effect?

On structural I like to see nice even welds with well wetted in corners and even leg length. You can play about as much as you like on non structural but you've got to keep in mind the loads the finished item will be subjected to.

And welding inspectors who will fail owt that doesn't look right

It looks like you are weaving the torch backwards and forwards plus as Paul says the weld looks far too built up on the surface with a poor transition at the toes, they would fail on visual appearance alone, sorry fella
