I am posting 30 videos in 30 Days for August …customer appreciation month at weldmonger.com. Lots of deals and giveaways going on too but you will need to sign up here weldmongerstore.com/blogs/weldingtipsandtricks
Thanks Jody, you've done a lot for the welding community.
I love that even tho this is just a sample piece you still finish it like a work piece. How you do anything is how you do everything.
Some people piss excellence, and jody tells me the e's and c's hurt like a bitch.
Jody there may be guys "doing better" on the internet, but a huge pile of the welding videos out there are hacks making junk. Happy I found your channel all those years ago. Keep up the excellent work.
the daily videos have been so nice, i love seeing that there’s a new video to watch every day. thank you Jody!
Oh yeah!!! Great way to start my Sat. morning by watching a TIG socket welding video.
Jody I absolutely love all your videos. You are hands-down the best educator on TH-cam when it comes to welding without a doubt. But I fear some of these videos are getting a bit mundane. Repeated video shots and stuff like that. It's hard to keep my interest. I will watch from beginning to end but it's getting hard you keep my undivided attention. Love you Jodi
Thank you so much for your videos at work. we would use 309 stick welding to weld mild steel to cast steel coal pipe and worked great.
Love your videos and the store…have learned a ton and your customer service is top notch!
Great stuff! 309L is a wonder rod for sure. And having a 3 jaw/turntable like that is invaluable for almost all small and large round work, for any process. Saves tons of time and minimizes start-n-stops.
great video jody! we use to watch your videos in our welding class in boces. everyone actually payed attention when the videos played. you have a way of making things make more sense. thanks for all you do for this community
I would be proud of those socket welds,thanks for all your instructional videos🤗😎🤗😎
i love how your videos always correlate to what im learning in my day, i just got my first tig job out of welding school at a local community college doing stainless work, theyre having me build some saw horses where the legs are made up of carbon sqaure tube, I am using 309L 1/16th on the top 2x4 stainless square tube, Im absoulutely loving it there but thank you for all of your knowledge!
Looks pretty darned good to me.
Great information! Thank you very much!
I’m trying to learn everything I can before I buy my first TIG.
Love your content, thank you very much. You're a great teacher, learned a lot from you
Always appreciate the tips and tricks.
Love your content mate!
Thanks Jody, great job and information and demonstration. Practice and knowledge of the materials and proper rods to use works great with time. Fred.
I like the features of 309l. Nice welding after a long time away.
Thanks Jody.
Thanks for the tips😁👍 great refresher. I had forgotten about the 2 pass minimum. 😂
invaluable, thanks
Beautiful!
Well done 👍🇧🇪 .
Rad dude, thanks for the tips. I was wondering why you were posting so much content.
316 works really well too,
Thanks
Fantastic info
Ohh! Perfect timing, I'm building a mud pump out of some dissimilar metal scraps. I have 308h stick rods on the self. I'll check to see if you have a video on the 308s if not I'll grab some 309s
Yes sir anytime you can use a positionare or a turn around it is a lot easier than doing in a stationary position but damn you sir have great skills in tig welding great looking welds
Отличное видео
Que de détailles comme d'habitude
Merci
Impressive!
Yet again a really excellent presentation, this is interesting as I have a situation to weld a carbon steel hydraulic fitting into I THINK a cast steel cylinder I've been putting the job off as I can find very little on what filler material to use and I wonder if this would be the answer
Great video. How do you feel about 316L for the same range of applications? Our local supply sells me that for the same price as 309L. 6:42
Good video and nice welding examples. Always be careful mixing stainless and carbon steel in real world applications as it can cause galvanic corrosion with the carbon steel as the anode. You can get away with it with large carbon steel mass and small stainless mass but the more stainless to carbon, the greater the corrosion. Isolation kits should always be used when joining carbon to stainless in a system.
I have used 309 to join carbon to stainless before, but never on just carbon steel. How well would it hold up on just welding stainless to stainless? Last year I welded up some stainless on a pin-plow for a bowling pin setter machine for my buddie's bowling Alley . I did not know for sure the type of stainless so I went with a 308 rod. But I almost went with a 309 as it is a stainless part but it is not really in a stainless application. A bit of surface rust won't hurt. In fact I repaired about six of these same panels about 20 years ago for the previous owner before my buddy purchased the place. I used a 309 then because I took them to work and welded them and it was the only stainless rod we had at the time. LOl
I looked my old repairs over last year when I fixed this part and they was perfect. I did not have any stainless rod at the house so I tried to buy the right filler. I might would of been better off getting 309 and had what was left around as a good all purpose.
309 the magic rod
“Lots of room for improvement”. Are we looking at the same weld?
What do you set your machine to for stainless steel
It looks compulsory a video about the E309L welding rod
What do we have to do to get you to write a book with all this information so we can reference it on the job ?
What would be good for Chrome Moly to Carbon?
What filler is more stronger Er-309 or Er-312?
Глаза!!!)

Now show tig welding Duplex to 316 stainless steel.
"I've got lots of room for improvement here..." Can someone tell me what's wrong with this weld? It looks perfect to me. It's what I'm looking to do. What's wrong with it? I just can't see it...
Wouldn't the RPM vary with the diameter of the pipe to stay at 1/8" per second?
Yes. That's what the marked tape trick is for; the "write it down in a handbook" would be for that diameter only.
Technically one could calculate the RPM using some math... but if the positioner's speed isn't accurate (or one isn't good with math), the tape trick works well enough. If it works, it's right!
Can someone explain the "gap" that is required? Where is it, and why do you need it?
Between pipe OD and socket. Gap is to allow for shrinkage so cast fittings don't crack.
@@mitchdenner9743 I ended up googling it. The gap is actually between the end of the pipe and the bottom of the socket.
"One of the requirements of the fabrication section of the American Society of Mechanical Engineers (ASME) Section III and ASME B31. 1 Codes is that when assembling the socket joint, a gap of 1/16" must be provided between the inserted pipe and the bottom of the socket."
When fitting a socket weld it’s typical to shove the pipe into the socket as far as it will go. Once shoved in take a soap stone or magic marker and draw a line around the pipe right up next to the fitting. Once the line is drawn pull the pipe out 1/8” of an inch. This will allow you or the fitter to get the pipe and socket fitting both square and plumb. If you shove it all the way in and don’t do this the pipe and socket will be locked into a position where they can’t move at all. Now achieving square and plumb will be impossible. You can buy a ring that is bent 1/8” that can be placed in the socket fitting to make the space for you and sometimes it is required. When required on a job they will x-ray one every once in awhile to make sure you are installing them. Hope this helps.
Why do socket sleds gotta have a gap? To compensate for shrinkage?
To compensate (allow) for expansion during the weld methinks.
My instinct says for getting enough penetration deep there in the join line where it counts, let enough metal fill in deeper and make an internal surface and not just a round lap joint that has already a weakness, in the shear surface line. But I wait to be corrected on this one.
@@nikspanakis but that gap what looks to be a 3/32, is inside the socket, it’s not where he put his weld. So he’s not getting any sort of root penetration.
The socket is cooler than the pipe in operation, causing the weld to be in tension. Over time, this causes the weld to crack.
@@fztfabs65
Socket fitting welds are filled type, not groove or butt. The gap is for pipe expansion so no thermal stress happen in operation when the pipe runs hotter than the fitting.
Jody. Rpm= surface feet per minute/diameter* a constant number of 3.82. Your moving 1/8 of an inch per second. 1/8 = 1/96 of an inch * 60 seconds which is your feet per minute this is .0104 *60 this will always stay the same cause your 1/8 travel distance is your sweet spot divide this by the diameter times the 3.82 constant and voila no more guessing
My bad 1/8 is equal to 1/96 of a foot
I didn't get the "gap" purpose.
It has to do with allowing expansion of the pipe within the fitting I’ve been told
@@JFROMM454 Thanks
Are there fumes you need to be worried about when welding stainless?
Yes, chromium hexavalent. Should use localized exhaust and papair hood (positive air pressure)
What about the rod itself?@@mitchdenner9743
