Thin 4130 chromoly tubing can be welded without a preheat as long is its .120" or below in wall thickness.
This chunk of 4130 absolutely needs a preheat of around 500F.
4130 is a hardenable low alloy steel and can have hard and brittle zones if allowed to cool quickly.
Preheat slows the cooling rate and by using a preheat as well as er70s2 filler rod, a ductile weld can be made.
Sometimes 4130 chromoly is welded with matching 4130 filler rod when it is heat treated to full strength after welding.
In this case, the part was stress relieved in a furnace after welding and was not required to be strengthened by heat treatment.

Your videos are always very informative, and your professional commentary and methodology is always a plus. Thanks

[@EnsignRho]

Love your videos. Would like to see more with recruiters / advisors who can prepare people for getting welding jobs, taking welding tests, what pitfalls to watch out for, etc. Really enjoy those.

[@erikd116]

You remind me of my welding instructor Victor Garcia. Not a social media star or well known name but a man of pure worth and dedication to this craft. Completely forthcoming with any and all knowledge, never agitated or even.. He volunteered to start a welding program at Washington State penitentiary. Tall order!!. A decade later and he's literally changed 100's of lives and dramatically shifted the future of society's wellbeing. I've got nothing but love and respect for people to go the extra mile and give without expectations. It's a beautiful thing I enjoy practicing every chance I get.. I learned from the best in the worst place!!. Thank you Jody.. you helped get me a job I really wanted and deserved.. nerves kick my backside so I used your video for repetition and visioning..!!

[@jd784]

I always appreciate the knowledge you freely share. Thank you

[@weldingtipsandtricks]

A few weeks ago, my machinist friend brought 2 parts for me to weld. I already posted the first part where I used a 2 pass weld to achieve the leg size specified on the drawing. For this part, I used a somewhat different technique.

[@darrenbrown2744]

Since this technique works for this crack sensitive alloy, I'm assuming you could use this for a medium carbon steel?

[@gabrielharris1845]

Laywire technique looks pretty cool. That is something I need to try with my powertig welder.

[@ronjackson1416]

Laywire technique produce great looking welds, but, not the best technique for welders just starting tig welding , because of the possibility of lack of fusion. The only way to determine if you are having lack of fusion, or cold lap is to X-ray, or cut and etch the weld samples.

[@renevanwijk9653]

you are amazing..greatings from Holland

[@brianwalk108]

Unbelievable skill

[@DirtyBikerbits]

Hey Jody, thanks for the videos, you're a huge inspiration, I literally started my career as a welder thanks to your channel. Ok, so here's my question. When you get given weld specs(I.e fillet size etc) how do you know when you can do multiple passes to achieve the fillet size? I've been reading up on welding theory and came across some information on minimum fillet weld sizes for a given thickness/range of thicknesses. Do you do any math work(I.e figuring out what minimum size fillet for your first pass) or do you just go off of instinct?

[@hussein.Alkabi]

Jody, First off I love your videos. Very informative, professional and you’re a master of your craft. I have been wanting to weld up a small money safe.

[@mrdauntl3ss]

So I got a job at a train yard and j never used a welder. They said fine I can learn. 3 days in I love it and could easily weld flat. The problem is I have to weld overhead horizontal and vertical with one pass on two plates. The steel had to break not the weld when they bend it I can never get a clean weld that has the heat pass through and it digs pretty bad on the overhead. We use Miller arc and a wirespeec of 4 and heat 24

[@Martuszewski]

What about pudding out on end. To keep it from cracking and concave?

[@amacca995]

Silly question but would you be better off reversing the direction so that the termination is not all at the one end? EDIT noticed you replied to another viewer asking the same question. Sorry.

[@winonabigbrownbeavereater2218]

Backstepping is also good mig welding on aluminumin

[@budd1814]

Very nice pictures of your weld Bob Ross.. Wait.. Wait.. Jody. A Question,, yes preheat,,No post-heat??? couldn't you use a mig and get the same result with the pre and post-heat? by putting it in an oven to keep the Brinell hardness in check? What pre heat did you start with? 700?

[@PrettyHateMachining]

Just curious, is there any reason you didn't go with something like ER80S-D2 for this weld? I use it for welds like this and it's fantastic, but I do not claim to be an expert (or even close to it). Your wisdom is appreciated.

[@Tuan86tn]

[@harryhino2267]

I have noticed that you rest the electrode on the weld during the post flow at the end of your weld run. Why do you do this?

[@DilipDilip-yq9bg]

Nice welding

[@uradumby25]

You preheat so you can get penetration or so that it doesn't cool too fast and crack? I am very curious about how to maximize the thickness of the material you can weld with a TIG welder.

[@aidancrawford9989]

How do you get the arc cone so narrow? On our shop's tig machine it seems to be very wide and I can't do a fillet weld properly. I could just be bad but idk.

Not sure why you chose to have the torch floating instead of using the internal surfaces to rest the cup in. Was it because you didn’t want to create scratches or is there another reason?

[@GoFishingOrGoHome]

How many amps do you need to weld this

[@ninjajames2928]

This guy is like the Bob Ross of welding

[@zEr0ic3Gaming]

So with something this thick, why didnt you bevel? Is there enough weld in there that it's reinforced enough to hold, regardless of the tension something that thick could go under? (Even if it isn't)

[@rhansen435]

Looks like a disc style control valve.

Re: Crater eye.... first pass … right to left. Would it help to run the second pass left to right or am I overthinking it ?

[@weldingtipsandtricks]

sometimes I do that. switch directions to even out stress. But wasnt really worried about this part because it was going to stress relief heat treatment after welding. distortion was not an issue either since the overall dimensions of the part was at least .050" oversize for final machining

[@justinhall8318]

Youre not over thinking it. I was honestly about to ask about the left to right thing until I came across your comment!

[@honda8354]

The taper of the tungsten,in relation to the diameter, should be 2.5 x,correct?The taper looks shy.I'm asking this for educating myself,because I use this as a guideline when I sharpen my tungsten. Any feedback will be greatly appreciated.

[@weldingtipsandtricks]

Charles Moore 2.5 taper is a good rule of thumb but for high amperage, less taper works fine and can get better penetration

[@deghgcx]

Wow..! Verygood

[@freesaxon6835]

[@nanukhapunga]

aftr few weeks? m right jody? bt nice tips..thank you w.t.a.t

[@dfza4866]

Forgive my ignorance, is that size weld joint strong enough for a 1 inch+ part. Penetration? Beveling the edge not required?

[@weldingtipsandtricks]

Daft Funk the drawing had a weld symbol requiring.250” leg size and I met that. The thickness of this part is more for dimensional stability than strength alone.

[@dfza4866]

@@weldingtipsandtricks thanks for reply would have helped if i had read your first comment explaining the task. As a matter of interest if you were welding for strength on the part what would the procedure be?

[@Kingfranz]

Why just 165 amps? Why not 200+ for that thickness?

[@keegan7ThatMe]

The thickness I don't think is an issue since he preheat at the beginning. 200+ could make it to hot and cause a slew of other issues.

[@YszapHun]

​@@keegan7ThatMe i'm no expert but if it's metallurgically stated that this certain material does not like to be heat treated by having extreme temperature differences a.k.a. welding stone cold material with 200+ amps, then it is advised to preheat and use less amperage to make it less of a "heat shock" for the metal
