Sometimes, drumroll, my TIG welds turn out not too good. For example, they could have "warts", or some fillet welds are concave instead of convex.
By the way, why do some welds turn out to be concave instead of convex. Should I use less filler and run my torch slower, or some such?
Can I, in these instances of bad looking welds, run the tig torch over that weld again, without a filler rod, in order to re-melt the bead and improve its appearance. As it turns out, doing that does get rid of warts and it does turn concave fillet welds into convex fillet welds.
The question is, does doing so increase, decrease or does not change the strength of the weld. Any thoughts?
As an aside, I am hugely impressed with tig. I could weld thin things (1/8") to thick things (1/2) and the weld looked really nice too.
What I really like about it is that I can weld very small things, like welding little nuts to steel plates, etc.i
