I am starting on welding aluminium,and the type of joint is in this way the thickness is mm.1.5 :
_|
so that the two edge have a light in the corner proximity.
I have tried in a lot of ways, but every time when I go on the external corner the edge is melted.
I try also with filler-rod with very bad results.
If the joint has no light and one edge is over the other I can see the puddle of the melted aluminium and I can weld with good results.
Has anybody an answer at my problem ?
