starting tig

[tracer]

is there any good you tube or other sites to show techniques of tig welding?

i am trying to start without filler rod, to try and practice gettting the pool sorted.


what other points can i practice?

how far should the tungsten be out?
whats the best shroud to use for general useage?

when ending a weld, should the tip stay above the weld as gas is still coming out(is this to cool the last bit of weld?)

ali or steel?

if you ever need any help tracer come round and i will teach you a few bits and bobs wi the tig.
most techniques are dependent upon the weld needed. ie fillet , but, outside corner etc etc etc

starting with steel

thanks wscotty

ive found it easier with stainless tbh. flows nicer. just remember to clean the steel really well. no rust oils etc. make sure you sharpen the tungsten the right way, leave it sticking out from a no 7 or 8 ceramic around 5-8mm for butt and o/s corner and a little more for fillets around 10mm.

try butting 2 pieces of 2mm ish steel. dont leave a gap or if you do make it small. i'm not an expert with tig so anyone who feels i am giving sh1t advice let me know.

oh try outside corner. its quite easy

normally only for stainless as it stops oxydation as the weld pool solidifys

Using 150x50x3mm lcs or s/s (thickness can be less) clamp them together in a vice like this> II< then autogenous (no filler) run along each edge till fused together. Good exercise for arc/hand and eye co-ordination.

Cheers.........

Ps, if using say 3mm thick, clamp together you will now have 6mm to fuse together.

tracer, have a look at this: http://www.millerwelds.com/resources/TIGhandbook/

Got me started quite well, learnt the lingo and some of the basics. Rest is down to practise practise practise... Which I've not done too much. Alu is hardest, thick mild and stainless is fairly easy. I've got a pedal which I've found helps a lot with the power. Enjoy!!

i know off topic but
everyone say aluminum is hardest i learned it and it was easier for me then steel might have been the machine but aluminum is pretty easy flows well and some time you will get uniform welds

That's what I thought too. At first...

Are the rods you were using for steel definitely and without any possible doubt TIG welding rods? Turned out I was using gas welding rods (not triple deoxidised or anything like that) and they made mild steel TIG a real pain. In my defence I'm not the first. Turned out mild steel TIG really is easier.

some were some might have been but with a welding instructor who has no clue about tig im not sure they were thick and copper coated but the teacher bought them and he thought the gas should be set at max regulator goes at which was almost 50 cfh
but we had a professional welder come in and show us how it was done and his welds looked perfect
