  • Cagnazzi Racing garage .. or just Cagnazzi clock on the wall

  • chrome-moly frame ...??

    will they employ for me for TIG welding?

  • I think self taught welders regardless of what they weld should leave the advice to trained ticket trades people

  • try what you like , i bet you cant break them. great vid

  • What's wrong with those welds? They look fine, and are probably very strong.

  • and, yes, I understand this trike is hobby-engineering work and precision welding

    and most metal-works is done by robots and industrial machinery in Germany, Japan etc

  • weld weld weld

    weld ja weld

  • what i know about c/m tube welding is preheat and interpass temps are very important, but most of the things i weld are heavier wall .240 and up.

  • @martinmartiini its fucking youtube.. millions of dollars/euros or any other currency used each year on some internet leisure toy...

    Want another example? I'm pretty sure I can do this for nearly anything manufactured now.

  • Comment removed

  • @martinmartiini Welded benches, welded seats, desks, tables and many other things are quite a waste of welding then.

    You can make all of them out of wood and save the welding for something important.

    There is enough filler material and electrodes to go around. They aren't a depleting resource like Oil. In welding schools they have to throw away thousands of dollars of welded material every week but it gets recycled into new steel and fillers.

  • @HitachiHenemaru metal oxydise, so it is depleting resource and you cannot use metals endlessly. There is already global shortage of all resources, including metals. Only 10% of humans on Earth are capable of using metals because of shortage

  • @martinmartiini sounds like globalist b.s... shortage of all resources? you must be the "stop global warming" type

  • @MrChronicBlunts yes

    ..but .. how much iron is there inside Earth's core ???? 50%

  • @martinmartiini If they didn't weld this thing together good it would crack and break, causing a danger to both the driver and anyone near him. the exact same reason they make sure cars are up to specification.

  • that one guy said try doing that out of position that guys not out of position that is gravy im a nuke welder in the shipyard i weld in submarines welding that cage up is not out of position try welding upside down with two mirrors and getting 100% on x ray or ut wish all i had to weld was a roll cage like that

  • @MrGlockallday If you can use two mirrors... you dont need one at all YOU CAN SEE IT! 23 years of welding boiler tubes 

  • Dear Peoplewhothinkthisguysucksatwe­lding...

    just because his welds dont look all pretty and stuff dont mean its a weak weld. its pretty much like judging a book by its cover, justcause its not full of colors, it dont mean its bland and boring.

  • @MegaMarty46 definatly, these stock cars are for performance, not beauty

  • I know its really tough to just get to all those spots on that that car frame. The vid shows an easy spot where the camera can see the guy welding. There is all kinds of out of position spots there where I'm sure the welder has to stand on his head and cuss (and still produce decent work). Imagine crawling in and out of that frame to go grind your tungsten every time you dip it. Your skills and advice are good. Todd, Thanks for sharing. What was that number of tig rod you're running?

  • Oh gosh! My dreamjob! I always wanted to TIG weld something for automotive branch and what's really important and what would require responsibilty from me.

  • me gustaria que estubiera suptitulado al español se ve que esta interesante

  • It is all in the tie in. So keep working on it. it is all the same

  • sexy beads. :D

  • YOU DONT REALY HAVE ANY SKILL, YOU JUST SH..ING AROUNG, AND YOR WELD IS REALY FUNNY XXAAXAXXAXAXXAXAXA YOUR BEGINER IN FABRIC WORKING

  • @TarantinoCicka your obviously from greece

  • @TarantinoCicka learn to spell before you learn to weld.

  • @TarantinoCicka

    How about you have a nice cup of stfu and show better welds in similiar situation.

  • With the cro/moly it helps fusion and post weld heat if the tube is pre heated a little before welding....not much, just enough to sweat out the moisture (this is used on tubing thicker than 3mm as a rule of thumb). overly large fillets aren't necessary or wanted as the video explains, embrittlement is caused by excessive heat in the weld. Also the heat can be lessened by using the pulse setting when welding (if it has it). As for the foot pedal....ditch it and get a thumb remote!

  • @alibong00 no its says:" cooling too quickly causes embrittlement." hand or foot control is just personal preference.

  • @markbenoit Sorry I wasnt clear, using excessive heat in the weld, causes more grain growth in the metal adjacent to the weld than you want. This in turn causes embrittlement in the grain structure. You really want to keep the heat input to a minimum with low alloy steels. using the big unnecessary welds to heat the steel is just silly.....use proper pre and post weld heating and cooling to control the quencing effect of the parent material.

  • "welding chromoly we want to concentrate the heat in a same area" wrong! this is what tig welded does, not is what is needed for welding chromolly. concentrated heat causes the weld to cool to fast causing stress to build up in the welded joint. this is why gas welding aircraft frame's works so well. this is one of the biggest misunderstandings of welding chromooly.

  • @markbenoit exactly right! a more concentrated HAZ it quenched faster by the cold material ither side of it, leaving a more brittle weld and HAZ

  • omg, if i would show my boss such a weld, he would laugh, even my first wld was much better then this, & i'm a trainee who welded first at 17

  • this weld looks like shit

  • Bevis dropped the a and dyed his hair lolol

  • ..I've done a lot of TIG on all kinds of materials...this is a very good informative video, and pretty nice work for Chro-moly...especially using a foot-pedal...or maybe I'll call it the knee-pedal..?

  • Why don't you use a thump control rather then that foot control?

  • @Tigman309 'Thump' control...you playing drums..?

  • @Tigman309 besides the obvious?

  • great vids

  • wow....lookin at those welds. you better get better..!!

  • LMFAO!!! TODD BEVIS!! HE LOOKS LIKE BEVIS!!! ROFL!!!

  • great vid,do you heat tread the material after welding ?

  • Who knew someone named Bevis could be so smart!?!?!

    all joking aside great video but I'm curious about the preheating I've heard you have to do when welding chromoly

  • Thanks for the video. If one is right handed what is the preferred hand to hold the torch?

  • @themainproblem hold the torch in the hand you are most comfortable.

  • youtube experts. gotta love em!

  • @daytonamon40 yes me to \:)

  • engineers are worthless at actually welding or working for that matter. your welds are uneven and ugly. If my welds looked like that the inspector would say "um yeah thats not gonna cut it" and not even xray it. I find it funny that miller is a sponsor for this video

  • @eastsideCHIEF  i can weld very good and getting all the certs for that, but also am a engineering student. so i have training in both welding and engineer. so not all engineers are bad at welding, and not all are worthless. i got my automotive and welding certs down before i went to engineering. this guy seems a bit like he isnt the best at welding.

  • @lucasbmxMDK oh , and i wanted to say that ive seen better mig welds then this on that thickness

  • I used zig zag depending on the weld

  • Man that is one expensive helmet just by the logo

  • this is greek to me i just took welding got welding this year sku jus started trynin to learn extra by watching vids

  • i see the holes in yer welds @ 4:13

  • im not trying to be mean but your weld is ugly and lots of undercut.

  • for being a professional and engineer i would expect those welds to look better. im not a pro at welding, experienced but not enough YET to open a shop. those welds look like something i would produce. theres comments of its cramped, tubings hard. tubing isnt that hard, chromoly can still produce nice looking welds. and the spots they showed arent in cramped areas so there should be no excuse. not talking shit so nobody get all rah rah rah at me. just disappointed in the final welds they present

  • @dewhwut I have to tell u, I have seen very good looking welds fail. I have seen very ugly welds hold up very well and not break. I see it all the time in the oil patch

  • is it save to arc-weld without a machine that removes the fumes? thanks

  • the welds look like 'shit' because they're welding on effing chromemoly, remember chemistry? chromium and molybdenum both easily form oxides, thus the 'shit' you see around the weld is from very minimal heat that it gets hit with from the tungsten tip. these guys know their shit. @claymansrt also this.

  • man for those saying they look like shit, you guys should really try being cramed in between all that tubing with your hands and arms out of position and using a foot pedal with your knee to control the heat and show us all how your welds turned out.

  • @claymansrt i completely agree pretty much half of the people on here probably dont know shit ab welding im ab to go to diving school for underwater and that shit is gunna be fun

  • Comment removed

  • these welds look like shit....

    

  • nice speech..thanx!

  • At that level they should look good and work good , and that's with gas lens? Sawing machine technic ? Wtf ? Oh boy!

  • Dear Yankquie.

    95% of the world - and the people in it, use METRIC.

    The remaining 5% of the worlds population - composes the ENTIRE "US and A" - some of whom still use imperial..

    From now on, can you use METRIC.

  • I watch the movie and say that he is a hobby welder.

    Final weld the show was certainly the best weld and the fans the very weaknesses and I do not think such a weld is good is not good.

    melting ditch and pipe ... You suck and I'm Swedish welding Master

  • Heh heh m Heh, it's Beavis! Just kiddin man! Great video, I'm learning to weld too, looking for people of expert level. I'ma' workin on it! Your video is very informative and articulate. Wish me luck!

  • 4 ppl need to go back to stick?

  • that takes some skill to use that foot pedal in such a cramped area. good job.

  • What kind of tungsten are you using for chrome molly?

  • Seeing a strong weld and a good looking weld I'm sure are two different things. This guy is obviously a pro and knows his shit! Seeing those welds made me 'think' more about what I'm looking at when I see perfect looking welds in daily life......maybe they are not so strong but they look good? The car body covers all the work anyhow. And the car is obviously being rode hard and not falling apart. Great video!

  • héh_Î_fËel_sô_lóNÉlÿ_tÕdÃý

  • Wow ! no very good looking welds, but I'm sure are very strong.

  • that was very well said!!

  • when you loud mouths do your weld vids will see how you do!

  • the welds don't look so good. But i guess they will do the trick.

  • those welds at the end look like crap.looks like a novice did it.

  • @mrat455 wow so many welding experts here... do it better you fucker and upload a vid

  • @mrat455 there awesome you dick head!

    

  • One thing I've learned since I started welding last year, is that welders can be real self-centered assholes. Everyone thinks his welds are better than so-n-so's welds. If this guys welds sucked as bad as many of you say they do, I very highly doubt he'd be in charge of welding up these NHRA chassis. You guys are worse than a room full of Christians who think they have all of the answers. Thanks Todd, I for one appreciate the info you have supplied to us welders!

  • @PatrickONB

    No shit. The biggest regret I have in choosing welding as my profession is the over-abundance of self-righteous asshats who will look at a finished product and say "ah, screw that guy, his welds are shitty... he must not know how to fuckin' weld, man!" These are the same douchebags who couldn't pass a drug test if they prayed to the Lord almighty for 30 days (get it?), and never consider what conditions or machine a weld was made using.

  • Very helpful video. I've been kinda struggeling learning on my Tig. But my Tig machine is DC only no foot control only a dial on the main machine.  It's a great machine for the price. Looking at a Diversion 180 so I can Tig Aluminum. My miller 212 is nice and the AL gun is nice but Tig is so sexy. Need lots more practice, but practice is fun too. I tried DC Aluminum with Helium. A pro welder friend of mine looked at it and thinks it would work if it was cleaned better, oxide membrane.

  • Those are some shitty welds that they showed. Talk about not having pride in your work.

  • @sgtsocom

    What is wrong with those welds? They're on a fairly difficult alloy, properly spaced, bonded into the base material well, and showing a nice and uniform spacing between ripples on the bead.

    Anyone who has been assigned to a unit under SOCOM wouldn't make their online handle "sgtsocom," unless they were either a poser or an admin turd.

    Next time I have a problem with my pay I'll come upstairs to have you sort it out so that those of us with real training can accomplish missions.

  • @ekfinn LMAO, its a game you asswhipe. Socom, look it up.

    Also, those welds are shit. TIG isn't suppose to look like that. Their standards are obviously low, mine aren't.

  • @sgtsocom

    Yes, I know there are about a billion games with some variation of "SOCOM" in the title, all played by insecure twats who live in their parents' basements, never wore the uniform, and never faced evil on the battlefield and prayed he would return alive. Congratufuckinglations on having such a deep and emotional connection with a game that you chose to use it as your online call sign.

    Further, you are nothing but a punk unless you can post a reply video of YOUR chromoly tube welds.

  • @sgtsocom You should show us how it is done then... From all the TIG welding I have seen, these welds are fantastic... What do you think TIG welds should look like? A straight line across the material?

  • what's an 83 wall? i hate the imperial measurement.... hhhhhhhhhhhh

  • @Soundgarden8497

    0.083" I believe.

  • what material is the welding ROD made of ???

  • awtzz your welding is bad tahahahaha..........

    watch my welding not like that its very ugly weld thahahhaa

  • awtzz your welding is bad tahahahaha..........

    

  • Beavis....I miss him.

  • Naja ich weiss ja nich wo du Einbrandkerben siehst aber wenn du das sagst ...

    sagt ja schon alles das du zu Einbrandkerben nur Einbrand sagst ...

    OMG

    weil man braucht einbrand (ins material) Einbrand ist gut

    Einbrandkerben nich das ist ein schweißfehler

  • 2:04 for first weld

  • einbrand keine gleichmäßige schuppung und die schweißnaht ist etwas zu dünn...

    nicht sehr gut

  • All we have is scratch start tigs with no heat control it's a little tough to pass a xray test wish I had a peddle or thumb heat control I have used one and the differance is like night and day.

  • I would say this guy welded for 5 to 6 years... keep it up..

  • work for chromalloy florida 13 years.. you need more gas as you weld.....

  • Its 1234 add wire 1234 add wire 1234 add wire 1234 add its not like a sewing machine..

  • Thanks for the video.

  • Good Stuff!!

  • thats a nice video!

  • okej...vi tar det på svenska då...Jag svetsa lite finare !!! än på på filmen.

  • i can weld much beter then those tubes...... :)

  • @imenhoteb The tubes didn't weld the tubes, the man welded the tubes... therefore you cannot weld at all if you are comparing your welding skills to that of an inanimate object.

  • yuck yall wana hire a real welder <<<<<<<<<<<<,,, common that looks like shit i would not go 200+ mph with those crappy looking welds

  • I agree with slipstream84. I wouldn't run those @ 210mph I can tell you that....

    And if you're wondering, my welds have been 225mph, and 45 feet in the air @ 110mph.

    Beyond the welds pictured, great video. Good tips (although I disagree with you about staying close with the arc to the puddle.)

  • awesome, great bead. 

  • thanx for the vid

  • No offence dude but those welds look shithouse and slightly undercut.A weld that hot needs more filler to cool the material faster behind the arc,Fuck that pedal off and get yourself a kemppi pulse welder.

  • Nice Fab work but why are you using a foot pedal? seems like a pain in the ass using a foot pedal, Only need it for aluminum

  • @k9forkids and silicon bronze. Especially when running from copper to mild steel.

  • This is THE 4130 welding vid, THX. Also funny how last generations tanks, drag racers and BMX bikes all depend on the same material.

  • I tried to measure the voltage between the ground and electrode with a volt meter. The stinking tig machine killed my voltmeter. What's the voltage between ground and electrode?

  • Super video!

  • nice vid. 5 stars

  • How can you heat treat the frame made up of 4130, after its welding is done?

  • @AnshikaJ The advantage of tig is you don't require normalizing of the joints as it puts less heat in than mig. If needed, you heat individual joints rather than the whole frame.

  • @Flim63 where did you get this info? tig is really a disadvantage on 4130 because it lets the weld cool to fast it can be done. experts say you should weld slower with large fillet welds, flat to convex (not concave) allowing the joint to heat up evenly. more heat with the mig is a good thing on 4130.

  • @markbenoit do you have any idea what you are talking about?

  • @brian357 he certainly does, markbenoit is right in what he is saying, to really do things properly when welding 4130 with a TIG all welds[and there respective HAZ] should be stress relived, it seems to be a common misconception that using ER70-2 filler rod cancels out the need for stress reliving, it does not, while it is true the more ductile ER70-2 produces a much stronger un-stress relived weld than say ER80 or other filler material thats closer to4130 its far better stress relived

  • @brian357 yes i do i have done allot of research on this as well as i have been a race car fabricator for 18years. the link to the write up on this video even backs up allot of what im saying. Their is different info there, then is in the video btw. both leaving out allot of important info IMO.

  • @brian357 If you wanted a small haz you would use less amps and smaller rod. not what you want for welding 4130! note in the link on this page it says to use 1amp to every .001" thickness and to pre heat if the 4130 is below 60degrees f, they are saying this to make sure you get it hot enough so that it doesn't cool to fast.

  • very informative video.

  • top video!
