That helps, but the best thing to do on aluminum is back off the pedal a little and add a dab of filler once you've backed off a little so the crater gets filled up.HAHAHA, sorry but that is pretty funny. Electricity + water = a hair raising experience.
IZ that looks very good on the aluminum. One problem I have run into is the weld pool at the end will cool too quickly and crack. I think you can slowly relax your foot toward the end of the weld and help to prevent any such problems. Keep up the good work!
Dips are spaced a little to far apart, they may look nice but having them spaced so far apart makes the joint underfilled as a whole and can lead to individual little stress risers at the dips.
Its also not clean enough, see the little specks in the bead? That is either grit from sand/emery paper or grinding wheels or oxides from not brushing off the alu. Grinding aluminum is fine with the right wheels, but you need to either go back over it with a carbide burr or a SS wire brush (NOT wire wheel) to get the embedded grit out of the material. Also even brand new aluminum needs to be brushed to remove the oxides.
Clean it, tighten it up and you should be golden.
