You should do a video on the gear used to start that process such as how you cut the tubing at angles. What machines do you use to lay that out to begin with.
I wouldn't use this lay wire technique as you won't get good penetration. It's also worth mentioning weep holes so your weld doesn't blow out near the end as the gas builds up inside the tube and has nowhere to go.
@Tommy S I never said he needed to backpurge. You don't need to backpurge 4130. Lay wire technique is fine for certain things but I wouldn't use it for a cage. I can tell as someone who has a lot of experience with chromo tubing that this man does not. If you're going to show something like this, on a channel this big, get someone with more experience.
Can someone include the stress relieving process that happens after welding? Everyone always seams to just skip this part of the process. I’m currently working in the aviation industry and all my 4130 weldments require stress relief after welding.
Can someone tell me why people say chromoly tubing is stronger than mild steel, when mild steel has a higher tensile strength, the chromoly is more rigid though.
Exactly. Use chromoly because it creates a shell around you. If you used mild steel it could crush around you a lot easier. Tensile strength is different from hardness
4130 has a higher tensile strength than mild steel, even cold worked mild steel. Its why 4130 exists. 4130 is steel and therefore the same stiffness as mild steel, Youngs modulus.
Love this ... would love more moto sports welding tips
Your video is the kind I really like and appreciate: all meat with no fat! VERY well done!

Excellent video!
Quality welds and quality information 🤙🏿👨🏾🏭💰🔥
Especially the first one, looked a little grey. See that a lot on here with tubing and no8 cups. Bigger cup + more flow. Jazzy 10 or fupa 12
use a gas lens
Great video!
Dude you are awesome brilliant work thanks for sharing this video.
Very nice, subscribed.
What tig welder was used ? Miller Electric TIG Welder, 50/60 Hz, 26/6A, 38 lb. ??? Thanks!
Miller Dynasty 200
Nice work.
nice!

Hes not back purging. Also looks like he got plenty good penetration at the end when it shows the completed weld.

Go to his Instagram, it's all pipe. Which is fine, he's really good at that. But my guess is he doesn't mess with chromoly too often.
@@yakswelding86 i must have misunderstood you, sorry i just assumed you meant welding gas. Also i dont use instagram so i havent seen his other work
Appreciate this video alot!
🤙🤙
Bless Enjoyed the video; however, show us the settings. Thanks 😊
Would like to see how you operate the pedal while working in a contorted position on a real chassis, upside down on your back....
I'm doing this right now on a real chassis. It's a nightmare.

Why er80. Ive always been told er70 is best for 4130n to avoid brittle welds.
I wanna know if chromoly actually cracks because its more rigid compared to mild steel
It can crack. That's why you can't mig weld it or get it too hot when tig welding. Other ways it risks cracking.
*2:15** What amps? Or did I miss that?*
Chromaloy is also stiffer...compared to mild steel
You would definitely trust components made by this welder. His emphasis is always on detail and quality. Great video again from David and WeldTube
same Youngs Modulus
Just keep the wire in the gas envelope and you won't oxidise it.

Exactly. Use chromoly because it creates a shell around you. If you used mild steel it could crush around you a lot easier. Tensile strength is different from hardness
Wrong. The mechanical properties of 4130n far surpass mild steel in all areas.
4130 has a higher tensile strength than mild steel, even cold worked mild steel. Its why 4130 exists. 4130 is steel and therefore the same stiffness as mild steel, Youngs modulus.
