Cooper Union FSAE TIG weld alloy steel uprights

[westwater73]

rubbish get out your saked

[ieatls1]

Jesus those welds are ugly as sh*t. You need alot of practice and less filler.

[mksav1]

tatty and messy

[jamesch13]

@mksav1 thanks for the helpful comments

[MrThegurew]

lookin good :) get your self some aluminum blocks or pucks to rest your hand on :) much easier to keep the hand steady, if you havent figured it out by now, dip on the outside of the puddle :) much more puddle control when you dip

[lb4906]

It doesn't look good to me. Way too much filler? It should not mound up like that. Looks like a mig weld now.

[jamesch13]

The way they're jigged up none of the important dimensions change appreciably, and the bearing bore is machined after the part is heat-treated.

I don't know how you can say they're "not that good" when you don't know their weight or stiffness. I assume you mean mill them out of aluminum? Two words: endurance strength. Aluminum doesn't have it. Steel does.

[PittFSAE]

@jamesch13 You guys build your uprights similar to us, dont listen to the *cough*fags*cough* who think milled aluminum is the only way to do it lol.

[plumbix88]

I don't understand one thing. When you weld the pieces don't they move and contract? and your upright is not that good. Why don't you mill them?

le mec, ilsoude comme un pied.

ugly

[tommenh89]

My profession is welding tig and mig. Manufacturing products for the oil/offshore industry in Norway, so sorry for my bad English :)

[tommenh89]

Wow, nice work, man! Kudos for the nice jig!

On the other hand, you should use more heat (10-15A) when welding the area around the cylinder, and a little less heat (of weld faster) and filler on the area where the plates meet to form a fillet. You should also practice more on welding with even motion / heat dispersion.

This comment is not meant to be negative about your work in any way, only contructive ;)

[beserka04]

Yo man , respect , i understand what your saying , most guys put their welding videos on here of the best welds they ever done and which they pobably have made hundreds of them so they got real good at it. And your right its most of the time all about the strength not the looks. KEEP IT UP DUDE DONT LISTEN TO THESE REJECTS THAT THINK THEYRE AMAZING AT WELDING

[jamesch13]

Thanks man!

[jordzzzzzzz]

sure its strong enuff.. but if it was done right it would be strongest.. we always want the best weld

[jordzzzzzzz]

3 words. Walk The Cup. thats a waste of time tiggin like that.

[jamesch13]

I did walk the cup on the fillet welds were I could... please tell me how to walk the cup on an outside fillet weld and I will.

[jordzzzzzzz]

go up a cup size... and its not really a walkings the cup. more of a glancing back n forth. what ever you do im just sayin keep the ceramic on the metal. helps with shielding. arc length, haz.

[sooom3]

i cant tell what this guys saying either, but those welds definatly look like they could use some work : /

[jamesch13]

I'll just point out that when most (not all, but most) welders show a video or pictures it's of one or two parts with not a lot welding that they spent a lot of time welding to make sure they looked perfect. I did all of this, including prepping, jigging, tack-welding, and seaming between 4pm and midnight one night, and like I said before I did all of the seaming in 3 hours (from 9pm to 12am). And, well, they've held up under brutal race conditions, I think that means more than a "pretty weld."

[fubang500]

HOLY FUCK another welder with a good job that cant weld lumpy FIDO ASS WELDS you put rage to shame with this shit and yes if i had a cam and wasnot focused on just making the best welds i would and could show your ass up

[jamesch13]

Haha, thanks? I'm confused, are you saying you'd show MY ass up or "rage's"?

[bodybager]

What filler did you use and what kind of post weld heat treat did it get?

[jamesch13]

ER80SB2, the same filler I used for my AWS and ASME welding certifications. The uprights were treated to Rockwell C 24-29, a good compromise between strength and ductility.

[rv7kid]

dude nice welding man and krazyraver69 why do u shut the fuck up cause lets see you do a better job asshole

[gonzalo85]

Hey man!! those are some tight uprights and welding! I have a lot of questions for you, we are from Venezuela and making uprights like that is better for us cause we don´t have decent cnc machines on campus, but are they strong enough? what is the thickness of the chromemolly sheet? this year we machined ours out of a 6063 aluminum T6 so they were light but we were basically specting fracture, so we are looking forward on making stronger uprights.. And why do you use pulse on the TIG?

[Jok3ri]

The pulsing makes the weld look like a line of overlapping coins, what does it do to the strenght of the weld, i dont know..

[jamesch13]

Not quite, dipping the filler into the weld makes the "stacked dimes" look, pulsing the welding current (at 20Hz in this case) changes how the weld pool flows and improves penetration with minimal increase in heat input. I do increase the current via pedal control when I dip the filler though, but that is different from the auto-pulse from the welder.

[krazyraver69]

ehh i would prob expect the welds to look a lil better but im nt saying they arent sound welds.

[jamesch13]

well when you seam weld 4 uprights in less than 3 hours (from start to finish including breaks) then you can talk some smack

[d3javoodoo]

NIC3!

[jamesch13]

Thanks Alvin, you're awesome. ;)

[AwesomeAlvin]

wow those are some pro uprights and very nice welds.
