Before I retired, I work at a nuclear power plant. We had a project where we installed a whole bunch of these for vent lines on various size lines. They were challenging to say the least especially when they were out in the field and not in the shop. Some required two welders, one on each side because it was impossible for one person to get around the weld-o-let. We did not predrill the holes because they were hot tapped later after the valve was installed. I wish I would have seen this back then it surely would have helped. Nice tutorial.

what does hot tapping mean

@anthonypuccio9575

It means you would do all the work with fluid still in the line. After you welded on the nipple you would install a ball valve with a hot tap rig which had a long drill bit with packing on the end to seal it. There was a vent line on it to catch the fluid and you would drill the hole without draining the pipe. It was challenging for us because we had to collect the chips and weigh them. They keep a little pressure (no flow) in the line to help force the chips out the vent line and into a bucket. Hope this helps. @@natenate2280

That final pass really looked good. When I start out I like a smaller cup with 1/8th Gap. You still get the penetration and it saves time. You can turn up the amps just a little bit with a smaller cup and go like hell. You seem to have more patience than I do. I slow it down at the end . Great Video, THANKS

Thanks bud, that small groove is just damaged cup.

do you run a wire brush down through the socket to clean the inner weld and see what the weld looks like?

Grab a grinder and open that gap, especially that part where you have lack of fusion or give your pipefitter to do that. Don’t forget, you don’t have to weld it if you don’t like fit up, soon as you put the tacks you own it!

Nice video and technique. What baffles me though that even now in 21st century in year 2023 people use obsolete radioactive tungstens.... I understand that some companies won't provide better tungstens but damn, they should really wake up.

@X3MTIG

Жыл бұрын

Hey bud, thanks for your comment. I agree with you, but it’s not only about companies being cheap or neglectful of their employees. The entire industry is like that. The main thing is, whoever is using thoriated tungsten, should be aware of radioactive dust created during the grinding or sharpening of the tungsten. That’s why respiratory protection should be used, and taken that seriously! It’s all about educating people, and I think many companies are failing in that segment.

@rixogtr

Жыл бұрын

@@X3MTIG Exactly, it's a huge issue. Also. Radioactive dust is being released while sharpening thoriated tungsten and with this I'm not sure what kind of particles does thorium release whether it's alpha, beta or gamma, but with the last two they penetrate through much more than just a paper filter. It would also make sense to discard the filters/the mask every time you sharpen your tungstens which is not very sustainable. Also, there are other tungstens that are far better performing than thoriated so really no reason why keep this obsolete piece of technology. Do some research on it and present it to the management team, alternatively contact OSHA equivalent in your country.

Beautiful work, but why the gap ?

They want full root penetration, that’s why you need a gap.

Сильно перегреваете метал, в сформированном вами соединении будет повышенная межкристаллитная коррозия. На таком токе нужно работать чуть быстрей. Нужно больше позволять остыть изделию между каждым проходом.

It can be confusing. You’d also want to level the olet to the hole. Sometimes the olet will be used to insert a probe into the pipe and you want the probe to be straight down into it.
