It is simply improper technique.

i said that like 2 months ago and was called an idiot on here.

i also second penetration pics. no sense backpurging if you arent getting through the material

 

Im not condoning it, I just recognize a pedal-pumped weld bead when I see it.

If u are referring to my welds then u clearly are just posting on here to get your post count up

No problem. I'm just not a fan of pedal pumping. It's really more difficult than welding properly, I think.

Don't think I've never been called that.

Are you welding every day, once a week, or what? Just be careful and watch what you read on the car forums. There's a lot of bad habits and bad advice on them.

Yeah im welding about every day. Yeah ive read alot about how people think it should be done. i dont take there advice.

welp, you figured me out kiddo!

 

the welds don't look pulsed (or pedal)

i'm a pulse fan. keeps the heat soak down. lets me weld more at a time without cooling. little bit slower, but gives me a little bit more control.

breaking habits is the hardest part of welding. everyone is an expert these days. looks like you figured out how to sift through the BS.

TIG welding is probably the last type of welding where I would worry about a respirator.

It's slowly becoming known that even TIG welding of stainless and aluminum can be hazardous. In time, I think we'll see more and more things being used, like respirators. I kinda dread it, but there may be no avoiding it.

 

if the rod contains thorium you really should wear one
its radioactive. but i dont think its used much anymore..i dont weld for a living so i wouldnt know i just did a paper on radiaon exposure from welding last year.

The welds look nice... I don't care what technique anybody uses to get a nice looking quality weld even if someone says it's "improper." Whatever works for you do it.

 

2% thoriated electrodes are all i use

 

industry here has set a standard that in most plants, petrochemical, oil & gas, even fertilizer plants, are requiring that welders, fitters, and helpers all wear respirators when working with stainless and aluminum.
it's just becoming habbit, same with wearing safety glasses under your hood. you just automatically do it.
the 3m speedglas helmets with the forced air filter system work really well for this stuff.

i hope you dont keep them in your pocket then. and weld in a well vented areas. especially when grinding the tips.

I've carried 2% tungsten in my pocket, in nuclear plants. These were places that wouldn't allow me to carry tungten out of certain areas...but nothing was ever said about carrying the stuff around.

There's very small amounts of radiation emitted from tungsten. You can get more exposure by working in a coal mine, or iron ore mine or steel mill. I wouldn't doubt that you expose yourself to more radiation by smoking cigarettes.

It is a good idea not to ingest (breathe or swallow) the dust though.

 

its not alot of exposure.

The estimated effective dose equivalent to an individual carrying three thoriated welding rods (0.9 g thorium) in a shirt pocket for 2000 hours (40 hrs/week x 50 weeks/year) was 8 mrem..


you get way more then that from a simple chest x ray.

i get about 25-30 mrem a month according to my dosemeter.

but im only a student x ray tech working 2 days a week. thats almost nothing u get way more going out in the sun.

but deff inhaling the stuff will do alot more damage.

 

wow looks good

i thought dosage was measured in sieverts, micro-sieverts, milli-sieverts etc. i've never worn a dosimeter that read in mrem before, but you're right the oh&s working limit is much higher than a piece of tungsten will ever put off.
i carry mine in a copper tube that i made so that i always have lots of nice sharp tungstens of different lengths for different tasks.

edit: i see now.
Equivalent dose is often referred to simply as "dose" in every day use of radiation terminology. The old unit of "dose equivalent" or "dose" was rem.

Dose in Sv = Absorbed Dose in Gy x radiation weighting factor (WR)

Dose in rem = Dose in rad x QF

1 Sv = 100 rem

1 rem = 10 mSv (millisievert = one thousandth of a sievert)

1 Gy air dose equivalent to 0.7 Sv tissue dose (UNSEAR 1988 Report p.57)

1 R (roentgen) exposure is approximately equivalent to 10 mSv tissue dose

 

ya sievert is metric.

oh man all those units and numbers are bringing horrible memories back from my radiation exposure class haha

 

looks good!

its way too consistant to be pedal pumped... i say it was pulsed...

as far as the radiation produced from thoriated tungsten, if you are so afraid of the radiation, use Ceriated tungsten...
