how can you tell the haz on AL?

if you try not to stir the pudle with it they will last a long time :) , i buy only Weldcraft, it doesn't say where they were made, costs about 1 euro/pc , i think it's the cheapest weld consumable there is, don't even consider the cost of tungsten when giving a quote. wife goes crazy if she finds t...

damn, i get things wrong sometimes , you're right.

hey, good idea , this is what i know and tried till now. 95% of welds on stainless 304 or 316. gray(ceriated)=used to love them till i stumbled acros lanth blueish(lanthaneted)=this is the good stuff. red(thoriated)= radioactive krap, why use it when not radioactive better tungsten is available???? ...

http://www.hobartwelders.com/products/electrodes-wire/electrode-chart/ you have a chart here, it says that only 6010 can be used with an AC machine like you have it also says they don't make it in 1/16 , maybe you can find from other store some time ago i did some bodywork on a Fleetside, the damn t...

maybe you get some reflection light under the hood .

no, it's far from perfect, you just don't know that. Could you please enlighten us as to why these welds are "far from perfect" and possibly could kill someone? I'm trying to see what you're talking about but the only thing I'm seeing is the small crater left after the arc start in the be...

if all Jakeru said is not working , then you must keep the tungsten closer to the weldpool, i bet this is the problem.

mild steel will spark and bbl just like cast iron if you use too much amps or weld speed is too low.

who told you bodywork can be done with stick? Mig or fluxcore or oxy.

no, it's far from perfect, you just don't know that.

and for advise , go to UTS Timisoara and learn to weld before you kill someone.

de weld in the foto is defective anyway.

i cant make a nice weld around the small pipe like in the photo
it's more difficult than i thought
tomorrow i'll give it another try

wow, so welding is not that easy afterall, i bet a monkey can do it tho...

put some argon inside. and weld it with higher amps as fast as you can.

does the wife know about your new investment?
mine would have a brakedown ...

so you couldn't find argon/helium mixed in a bottle and decided to spend 12 hondred on a shiny box?

is dat a known (scientific) fact or something somebody told you? i belive the thikness of the bead has a bigger influence in failure of high heat sistems then a hot(ish) weld, and i've never seen a fully penetrated weld that looks golden on the outside, not on 1,5-2mm ss and not without backpurge

weld looks straight, looks a little hot to me... how thick is that material? when i weld stainless i will literally do 5 beads and stop postflow and start again after a 30 seconds for cooling. and you have seen my stainless welds :) it's not hot at all, the wall is very thin, 1 pass , freehand. if ...

it's 1,5mm wall , no gap 40A L1 , ~28 L2 , 1,5 sec l1 and 0,2 sec l2.

but that was just training in 6g pos and goofing with pulse. almost never had to weld anything at 45 in a factory, some 800 OD steam pipes ..

inside looks like this

i really want to see those "beads"

damn, i'm wishing for a 911 almost all of my life

about the second class, well u got some end craters that could be nicer

here's a 6g weld I did playn with some pulse setings, 304ss

don't worry about it, it's first class job, it's about 2 years since i welded some alu, if it comes out like yours i'll be pretty happy

p.s. i wouldn't work for somebody who owns a Datsun

the electrode should be grinded when it's contaminated, even if it looks ok but u know u diped it just a litle bit u need to grind it again. with the right size electrode, enough pre/post flow, u can weld hours , still i like to start the day with a newly grinded one. some types of tungsten may give...

Im in the same situation too except there are good places to work at here in south Carolina. we got a couple of nuclear plants and plenty of heavy industry comanys that i want to get into. but im fresh out of high school and got little experiance in a real welding work place. i can stick mig and ti...

it looks very nice, how's the inside?

i see nobody wants to answer your questions, i will try to do that. 1 , band saw blades, i've done it a few times with 1,6mm tungsten , would use a smaller one if availble, i can also say if a bandsaw will brake, it will have more cracks along so the weld might hold up but it will brake soon somewhe...
