Hello,
Lately I have been doing a lot of tig welding on steel parts without filler rod.
I call it fusion welding but not sure if that is correct.
I am really happy with the results, excellent looking welds and strong enough for the purpose.
My questions relate to the process and do's and don'ts if any, thoughts?
I get a bit of under cutting on fillet welds, the inside corner of square tubing mitres, not a problem as it looks quite good and is very clean. Any flat welds are amazingly almost flush with the surface and at worst just below.
I can post some pics of the results but I just sent out a large order and didn't take any good pics of those welds.
I have been welding mitred frames out of square tubing mostly, it is fast and there is no cleanup after, the weld is smooth, clean, flush and looks good. I have only recently been able to do the "fusion" welding because I am cutting my stock with a semi-auto cold saw and the cuts are superb. The joints fit nearly perfectly right off the saw and are very easy to weld without filler rod.
I have a Miller 200 synchro and an air cooled torch. I use the rare earth tungstens which IMHO are excellent.
Thanks for any input,
Cheers,
Michael
