I think you should write to some of the major welder manufacturers as it might be something they would like to investigate and the publicity around something like this certainly would not do them any harm.

Yes and I really know now why it's called a pressure welding test.

Ok, I see it all much more clearly now. Thanks

If I'm not mistaken the flux technique is called vapor-flux. I did a heap of welding with it years ago making motorcycle accessories, clip-on handlebars, carriers, crash bars etc. We linished and polished all the steel tube components first, then used vapor-flux with Oxy-Acetylene and Bronze filler...

Looks like bronze to me. There is a guy in the UK who posts on Instagram who does some amazing work using a torch that puts the flux in the flame. Seems to be really popular over there for for custom motorcycles Sent from my iPhone using Tapatalk You mean Oxy torch? How to do...And get the 'Stack o...

Hmm..Colour suggests bronze?

[quote=" Kemppi, still made in Finland. Did a little welding on ali with a mastertig if I remember correctly. They make very good machines as well. EVM, German made, considered to be the Rolls-Royce among welders in Europe Fronius, from Austria ?, high end machine spoken highly about. [/quote] ...

I gave many, many test's to welders in preparation for boiler repair jobs down thru the years. I have seen funny things happen in the test booths as a result. Had I talked with some of you blokes a few years ago my welding experiences might have been easier. I passed the TIG pressure test 2 years a...

That's not odd, that's standard procedure, and you'll never have to worry about that ten-year retest. Buying the bottle was almost like buying an agreement with your supplier. They have no reason to check their records for a contract when they can sell you gas. Steve S[/quote] In that case, definite...

Ok thanks Mike, but odd thing is, they swap over cylinders which means I no longer have the one I started out with.

These are the best gloves I've ever used. Bought a few pair and then could never find them again here in Oz.

I like!
I bought my own E size cylinder here in Oz but I never checked about what happens when it reaches the end of its lifespan, 10 years I think. Also, my gauge shows Co2 at around 500 kPa.

I'll probably get a geared 12v servo motor, with maybe 5rpm at the shaft and gear accordingly. Need up to 26mm per minute but next question is that of the return contact. Maybe a small copper arm, spring loaded to maintain contact while the work piece is turning. I think I have the purge attachment ...

That said, the Kj/mm is an upper heat limit, or travel-speed quantity, as was mentioned by another. Just stick with the WPS amps, and move fast enough you don't make it black, and you should be fine. Steve S[/quote] Thanks, but I have to admit it's got me in a knot and I'm thinking now of making a m...

I was given all the details including the amperage range and travel speed, I just haven't included all of that here. It would be great to see all of the settings. Might put everything into perspective a little better for others to follow. Thanks Trevor Well, the procedure was supplied 'In confidenc...

Yes, those blades on an angle grinder(or ankle grinder?) look diabolical but how about the twin blade saws with counter-rotating blades? I've never used one but would have to be a vast improvement over single blade running in one direction. In boat building I've used routers without any issues at al...

There should be given the amperage range to follow. For example 70-90 A. That kj/mm is heat input and it's bit weird that it is given if amps are not. Voltage does affect to the heat input as well, but usually that is not given for hand welding due to change of your tungstens hight. 10 volts refers...

Yes.

Some newbie weld engineer was trying to use his new vocabulary. All he really said was, "DC-"

Ha!..Thanks Steve, confirms my suspicions. Thinks...Must remember to read between the lines.

Yes, Speedglas 9100 is definitely the best I've had. Took a bit of setting up but once done, very comfortable and it switches off automatically after 20 mins. when not used.

Thanks and is dc,-ve to torch possibly just a technical way of saying dc-?

WPS for TIG states; Current and Polarity, dc, -ve to torch and I haven't seen that before. I'm doing stainless, so dc-.
It also lists Arc energy range to 2.5 kj/mm and Voltage range of 11-12V? Both of which I've never seen when talking TIG.

Thanks, I almost didn't make it! On the 3rd pass of the test in 2G position I got a nasty gas bubble which I've never had before and I was about to throw in the torch. I decided instead to grind it out and continue....It definitely pays sometimes to hang in to the very end. Otherwise I might have be...

Hi all,
After all the drama over the cause of my problem, I've come to the conclusion that it was the wire type. At home I was using ER70S-4 but I should have been using ER70S-2, "SuperSteel" which is triple deoxidised. Anyway after all that I finally passed the #7 certificate.
Thanks, Jeff

Hi Steve, Thank you and to others for the supporting comments. So, if Argon/Helium, do you have an ideas or experience of that if it's used on low carbon steel? Greater heat input yes. As for your experience with Tungsten electrodes, if metal dust ends up in a tool kit, which it inevitably will, the...

Hi Mick, Yes, very good info in all those. Makes it look easy....Ha! If only. Cheers, Jeff Hey there, I wish i knew about Jodys' vids when I did my number 7. Most of the time I was flying blind. I told a recent group about them and they loaded them up on the teachers laptop in the class room. Mick
