Einer, why are you trying to weld ally without filler rod?, It can be done but for bodywork it is not really desirable (for the most part).
Using a small amount of filler rod like I show in my youtube footage will yield better results. David

I try mostly because in some cases I cannot get to the backside for grinding/filing. Then filler "lumps" will make it more difficult to planish. And I must admit to some degree also for knowing I can do it when there is an advantage. But I take your hint and will instead try doing it with as little rod as possible and as evenly as possible.
Do you think the cracks are for lack of filler? I use 4043 filler rod. The aluminum is 10xx. I don't remember the exact number. I use a 2X reducing flame. Is that about right?

Hi Einer is it 1050A you are using?. I cut a strip from the sheet I am welding to use as a filler rod.

4043 filler may be your cracking problem. 1100 filler or a strip of the parent metal as David recommends would probably be better. |
