2% carries the heat better, I've founded with 2% if you accidentally dip the tip goes all furry and the heat isn't directed as much.

with aluminium is not much use, the ball dances around and doesn't seem to stabilize.

I'm sure it was walked, the cap is walked for definite, I didn't take photos of the cap because it was wire brushed with a steel brush so it's got specs of rust on it. how has he/she got the protrusion on the root? I've tried small and big gaps, high and low amps. I can get the ripple affect by walk...

use some foam or for welds close to the purge hose stainless wire wool or wire pad.

hi all been a while since my last post, been super busy. anyway i was removing some pipework from site today and came across a 8" - 6" reducing piece that was no longer needed. i new the welding was good because it was on a caustic acid job, anyway cut a long story short, i was amazed by t...

Hi guy Im trying to learn to walk the cup inthe 5g position, in need to learn for a job i want after my apprenticeship, my tutor doesnt know how to so ive been watching YouTube videos. I know the technique and understand how it works, but when i try my puddle seems to wash away from me and when goin...

I was modifying some pipe work another company had done it was schedule 10s stainless steel. I wasn't allowed to take photos but the closest I could was this photo on google http://www.tiptig-international.com/sspipingprint.html It's the second row down, third one across. I know this is that tip tig...

My boss is an alright guy, it's just I want to push my skills to the limit. There's only two welders at the company my mentor and me, before I was an apprentice there was only one welder. My mentor can't walk the cup so I have to learn from youtube videos. Ever since I passed my codes in tig he's no...

I have seen guys walk the cup on 1/2 inch pipe and it looks good but sometimes you can see a lump in the tie ins, I'll try and get some photos of some. I don't do much cup walking, 90% of the work I do is schedule 10, plus If my boss sees me practicing on plate or pipe he don't like it even though I...

Purge set up was 15-20 cfh these pipes were quite long, I allowed it to purge for about 3 minutes. I didn't walk the cup because I'm not confident enough to do so, I didn't want to slip and create an oxidised area. Plus to be honest I wouldn't practice to walk the cup on schedule 10 pipe and risk bl...

hi guys just a quick upload of some of the work ive done. i wanted to take more pictures but halfway through my boss told me it was a rush job so only a few pics. these were welded more or less in the 6g position (it was an aprox 45 angle, you might notice the cap is in a different direction to the ...

I'm an apprentice and I have passed two codings. I need to pass for my apprentice scheme full tig which I have passed. I also need a tig root with a stick fill and cap. My boss says I need to use e6013 for the test, but I've never heard of a test using e6013. Apparently all pipe welds on carbon stee...

Hi guys, I'm using 7018 low hydrogen electrodes, I can't seem to run the first bead on the cap, it runs ok but when I chip the slag of it looks like it has cold lap on the bottom, like a lip on the bottom toe. I run horizontal between 115-120 amps. The runs on top look we'll fused its just the first...

Thanks for the great comments guys, much appreciated. I'm a apprentice at the minute, I've been welding pipe for around 8-9 months, I'm in my second year at the moment. The face welds on the flanges were made with the aid of the tig finger, so thank you jody. I used a large bore gas lens for the fac...

hi guys,

just a few pics of some flanges i welded, some 2" and 3", all welded in position (no rolling), left and right handed.

all comments are welcome

thanks

Hi, Wondering arc on stainless steel is a pain especially on thin material. Try a really fine point on the tungsten with no contaminates on it. Even try a 1/16 tungsten. Use just enough amps as it takes to just form a good size puddle on the thicker material and add filler (1.6mm) then wash the pool...

That ok bud, post some pics when your done.


Cheers

Ive always looked up to jody and his welding and thought of him almost as a welding Yoda, we all appreciate the videos he supply's us with, just a quick ask though. It would be interesting to see stick and tig welding inside corners like on angle iron and channel. I've done a little tiging and stick...

I've heard of people using wire from mig machines with fine delicate work, but for your job, 1.6 mm if fine. As its carbon steel cup size isn't that important any size from 5-9 cup would be perfect if you have a gas lens that would be a bonus, but its not necessary. Just remember with thinner materi...

Thanks for the great comments guys.

Much appreciated.

hi guys

just a few pics of some of my work today.


im just an apprentice at this stage so go easy on me.

all thoughts are welcome.

these are suports for a manifold.

If you have a 1/16 electrode then use that, the arc cone will be smaller and give more control on thinner material. It can be done with a 2.4mm electrode and give pretty much identical results its just skill of the operator, as you mentioned this is your first pipe weld. Just take it steady, use low...

Thanks for the advice guys

I've tried the technique with mixed outcomes, do I aim the filler into the arc or pool and how do you build metal on the inside of the pipe when welding overhead.

But I can't seem to find a balance on the surface tension with the filler rod and it wond build on the inside.

Hi, You can Use 309 stainless steel wire but because its a exhaust manifold it will be constantly doing hear cycles of heating and cooling, as stainless has a different coefficient of linier expansion, the welds hold for a while but probably will crack along the toes of the weld. I've done weld repa...

I find a small wire wheel on a small cordless drill polishes perfect.

Or if welding stainless steel use the pickling acid paste.

Hi welcome mate,
