It depends how non continuos. The critical thing is not to overheat the cro mo. With thin walled tube and constant arc the weld is too cold at the start and too hot at the end if you get it just right in the middle. This technique gives a high degree of control over temperature and penetration by manual variation of stitch and gap time but you must always be careful to blend one stitch into the next. Use a hotter setting than you would for a continuous weld on the same material.
How hard would be to add a steering wheel insted of the classic recumbent steering? I know it will be heavier, but I don't really care. Looks so much funnier.
@dodden1 For small numbers a mandrel bender is used. Cromo will tend to kink if not constrained in a former while being bent. For large numbers a press is used (Outsourced from Taiwan)
what type of tig welder,size.Did you design the bike and all the assembly jigs ?Is this your company ? thanks for posting,giving the rest of us a little insight into what goes into building a recumbent trike.
The noise during tig is pulse not AC. AC is good for Aluminium. Pulse is not necessary but it helps get a nice weld with a little less heat and good penetration on CroMo.
Is TIG welding the standard for bike building? I would have thought that MIG would have been more common... but I'm certainly low on the expertise on MIG/TIG. TIG sure gets some nice results tho.
I have a hypothesis about why recumbents are notoriously poor at climbing hills when compared to standard bicycles and what to do about it. People who understand mechanics know that you can transfer the most force into turning a crank when the force vector is at 90 degrees to the crank arm. But there are some additional factors to consider: First is that straightening and bending a knee is a complex movement and probably has a "power band" (to borrow a phrase from internal combustion engines) that may not coincide with the 90 degree angle mentioned above. Secondly, you can stand up on a regular bicycle and get full advantage of this power band by storing potential energy using your weight and allowing gravity to buffer putting that energy into the crank at the best moment. Thirdly (and perhaps most importantly) while you are standing on your pedals (pumping), you can shift your weight back and forth slightly so that the 90 degree angle mentioned above is not just a passing flash but can be extended through several degrees of rotation. Some, if not all of these issues can be mitigated through mechanical design changes. Possibly a sliding spring loaded seat, an elliptical sprocket, springs elsewhere designed to buffer energy, or maybe something besides a crank attached to a sprocket to transfer leg motion to the chain.
I've been welding and fabricating for over 20 years working in sheet metal shops and aircraft manufacturing plants I'm a cyclist myself, I ride over 15 miles a day on my bicycle. I've often wanted to build a road bike myself out of aluminum stock and of course it will be tig welded, I would also be interested in building a trick also. I am interested in getting into the business of manufacturing custom made bicycles and have large shop I could work out of at my home
Also I have never had a weld failure using stitched MIG (have done probably over a thousand frames this way) but I still prefer to TIG thin walled cromo.
Expensive but worth the price cause the enjoyment one gets by riding those trikes is beyond words.
Hey Dude ! You are very good welding ! High Quality ! I might be to buy Recumbent Trike, as soon.
Un bravo artigiano, ne restano pochi.
High quality work there !
Came for TIG welding, stayed for Chega de Saudade, my favourite brazilian composition
Fantástico. Soldador de mão cheia, curtindo Beatles e Bossa Nova
Nice man! Professeonal made👍😉
When is part 3 then.

what size pipe is that and how thick is the wall on the center beam beautiful
Wonderful work, How can I have one frame in India ? Can you ship it? At least give me the dimension & angles.
Thanks in advance

Gr8 vid! I see you were using Pulsed Tig. What were the settings?
beautiful
Parabens linda musica...trilha maravilhosa
Me siento taaaaan inutil jajaja me asombro tu video, excelente trabajo. Saludos
Awesome video, and great job. Thanks

Hello nice work.
Why does it makes noice when you tig weld? Do you use Alternative Current?
Nice music by the way.
Best Regards
Высший пилотаж.
Cool bossa nova music !

Bluuplanet : what when you are 65 on medicare, u gonna ride a trike run your mouth.
are there prints that you can buy to make your own trike.
the song is really nice! brazilian ReB
nice welding tutorial!

Mostly Tigged but some trikes were migged. Brazing only for bidon bosses, cable guides and clamps.
welding a non continuous arc with the mig, doesnt this make for a weaker weld?
How do they bent the tubing for the seat?
i love your job !
A música é brasileira, traz paz ao ambiente de trabalho
How did you get Bill Murry to do the brazing job ?
+Rocky Styer LOL -- did not see it till you mentioned it - bill in his younger days for sure!
brazilian song is really nice!
Awesome job! why are you making spot welds one behind the other when mig welding , instead of making a countinuous weld ? Thanks
Stitch welding with the MIG is a great technique to control penetration into thin walled tubes.
This looks so easy with a TIG Welder. I used up 100 electrodes with my stick welder and it looks shocking.
clearly, the horn on the chop saw is the most critical part of the entire process.
Also I have never had a weld failure using stitched MIG (have done probably over a thousand frames this way) but I still prefer to TIG thin walled cromo.
I see some aluminum trike frames being hyro formed,i'm guessing its safer,less chance of damage.
Eu coloquei logo negativo Por que você não conversou nada só colocou fundo musical o vídeo ficou sem explicação então nota
I guess this is why they are so outrageously expensive
Isaac it’s unjustifiably expensive. You can build your own for 20 times less. It’s not like the king of England built it.
Jeep Rubicon I don’t have the skill set to build it, wish I did since building your own is so satisfying
Greenspeed GT 3/5 ??
Hola soy de Argentina cuanto sale un chasis de esas bicicletas
@wranga88 no it does not...what you do is weld until you see the puddle start to fall through then you let off...its just as strong...
ta euvi o video mas oquie isso????.
Классно! Молодец!
wow----
TIG is standard. MIG adds more material therefore weight and is generally less attractive
minuto bom, conto custa cada um! gostaria de atiquerir um👍
a qui no Brasil não se ver muito essas bicicletas ✌
Welder tutorial? 😬
uau very nice. like

I WATCH TOO MUCH VIDEO ON YOU TUBE SINCE 2011. THIS VIDEO I SAW THAT TOO MUCH BORING AND I WANT TO SLEEP..
Since its outsourced from taiwan I will not be buying one. There are plenty of guys making bikes entirely in the USA.
dude this is made in Australia.. not taiwan.. did he look chinese to you?
enjoyed your video.. i wish i had access to a TIG to learn on..
