- When I was asked if I could create this Copper Havan Kund I was excited to take on the challenge. Personally I find myself most motivated to grow my skills when I am actually producing a project rather than just practicing. After CNC Plasma Cutting out the Side profiles and bending them into shape, the Brazing began and the learning really started!

Thanks for another cool video (and for having an awesome attitude)
working with copper is a challenge. As a plumber, I would have oxy/acetylene bronze welded it, under the butt welds I would have pop riveted a tab under the joint, using stainless steel rivets to hold the corner down, then drilled out the rivets and then spot welded over the holes. Interesting to see silicone bronze welding though, nice work.
that looks amazing! nicely done!!!
What an honor of a project
It came out amazing, the recipients were the ones that enjoyed it the most.
I think Tig would of been way better for this Project way more fine control over tig compared to mig brazing
I honestly didn’t even know you could mig Braze tbh.
@@MichaelSmith-sj5uk yep you can braze in lots of different ways
Or just soldering.
@@oxygenium92 true
Great video Richard Brother hope you and the family are well bro
Pretty cool project.
Personally i would have given 2 of the sides ears to overlap to the mating sides. Avoiding but joints. A pair of duck bill pliers could take care of the ear bends. Then i would have soldered the whole thing together. But then i'm coming from a metal and tile roofing background. So we worked on copper pans and flashing quite often and had the soldering equipment for it.
Came out awesome Richard... Nice job!
Amazing work Richard. Living in West London, regularly visiting Southall, one of the largest Indian populations here in the UK and Europe and having Hindu friends, I am happy to say that I learnt something today from a man, self claiming to be of many origins. I know you will have enjoyed the wedding because they have a great celebration.
You said the magic word. Solder. I would have soldered that whole thing.
I think you did one hell of a job. I have welded for 30+ yrs and I have never welded copper. So there is always something to learn. I can see it is a very expensive lesson when you mess up. Take care and stay safe.
Aluminum removeable backer chill plate and also back stitching would help. all in all it looks very nice!!! good job
I learn lot of things from you....lots of love from India ❤️❤️❤️❤️🥰
Glad to hear, how does this Havan Kund look to you?
@@42Fab YES..ITS LOOK VERY GOOD...TO ME...
Jai ho good job. Loved it
Bet you had a blast at the event
Nice Job but I agree, Copper can be difficult to deal with. Indian people are very nice and their food is Awesome. That was a great honor to be asked to make that.
I haven't been as well fed very many times as I was at that wedding
Place a large aluminum chill block under the corner seams, tack every 5mm while using a cold chisel to manually press the seam flat against the aluminum while tacking. Rinse and repeat until you have a continuous bead. Use wood or whatever under the chill block to increase its height as you move to the upper seams.
What is the sheet thickness size ?
If you ever do another, add tabs to the horizontal parts, and bend under. Then clamp both together when you start to weld?
yeah, not a bad idea. adding a back piece worked well too
I would have used TIG and si bronze or actual copper wire. That is the tool i have on hand. However excellent result. Good job man. I am Interested in this machine. Props.
I never tried to mig weld copper with my 220 MTS. But after watching this I’m going to try it for myself. I’m and old school HVAC tech. I just guessing here, but possibly just using silver solder w/flux and a old school OXY/ACC touch with good regulators may have better butt weld results on this stuff. The right small flame 🔥 just might work out. Heating both copper sheets at the same time slowly with a small touch flame dabbing with silver solder should flow smoother compared to heat generated by the mig. Just food for thought.
There are a lot of ways to skin a cat, I do it in the way the customer wanted and paid for.
Hi sir, looks amazing, my question is to braze brass to brass , 10mm round rods to 10mm rods . I have done some mig brazing but too much spatters and difficult to clean .
Spend the time to dial your settings in.
@@42Fab Do you recommend any good welding machine so have less spatters for brass to brass braze. I do not mind paying for good welding machine specially for brass brazing .
You are probably better off TIG brazing in that case. The HTP invertig 210 is a great add, I just picked one up.
what I on butt joints is the gun angle is to steep and argon coverage is not good need to more 90 deg don't get me wrong I have zero experience with copper plate on tube but looks good its hard to work with !! Do you how tig braze a lot less heat into the parts ? I would had tig brazed the mig to mush heat
mate if you ever get more copper work what i do is cut small strips of the same material you are using and use that as a filler rod, that way when you blend it you get a nice even finish, also tack your flats very 10 or so mm so it wont pull apart from you, and tig is the way to go. all in all great job
I have rigged copper with good results accept I had to use argon and they recommend helium but there was a shortage of it when I did it last year not sure about now the helium makes the amperage way hotter because the copper soaks up the heat very fast, and all that’s required for filler wire is stripping copper wire from household Romex wiring or for your case something thinner
Tig welding or carbon arc welding with silcone bronze tig rod will make a neat weld better then mig
Curious as to why you didn't just tig braze this? Or even oxy braze it. If you oxy braze it with a 000 torch tip, the braze will just flow into the joints and be silky smooth. You may still have to deal with warpage due to how thin the material is.
Lots of ways to skin a cat
That's a really expensive havan kund! Nice video mate
Custom is never cheap
@@42Fab i know, been doing for my car, consumes a lot of man hours.
That was unexpected but funny as... pulse
Nice job Richard !
1:20 it suits you well... you wife has something from Jasmine and with a white beard you could have ruled Agrabah ;)
Wow 400 dollers a sheet dang
Attacking that butt.... weld.
guys, this is not a braze. This process should probably be called copper welding. It is not relying on typical braze joint physics, instead it is relying on weld physics. A braze joint would require penetration into a lap joint of significant size, from what is defined as a braze, you do not have braze strength here, here the strength mostly comes from a fillet, not from a lap.
you cannot braze a corner joint. Not in a way that it would make sense to analyze the joint under the umbra of a braze.
the fluidity rating of the filler must be high and there must be a significant lap joint for something to be called a braze in my opinion. When people remark about how strong a braze is, that is what they mean.
the alloys used for copper welding vs true brazing are different. A true braze would use a silver solder or something that flows really well. Something that you butt together with a goopy melt is more like a weld.
Hey i´m seeing much spatter. could it be that the polarity is wrong? you know like welding with no gas flux wire you have to change the polarity otherwise you are getting much spatter... My theory is that if you change that you increase your economic use of the wire. would you confirm that?
This is silicon bronze wire being pulse welded. The machine is set up correctly, as is the gas.
@@42Fab ah ok thank you for your answer!
Did i see you weld over your tape?
Come on man!!
Painter's tape completely burns away well ahead of the arc
You should also 100% wear a resiprator when grinding at the end. All that crap gets into your lungs. Not good.
100% do whatever you want to in your shop
GOOD BUT NOT PROPOSED SIZE
How so?
You are simply better off Silver Soldering the joints with copper sheet.
Cracking job though!
I would agree if it weren't for the fact the recipient didn't want to see solder joints, which I find reasonable as they're ugly compared to a SiBro joint that nearly blends in
Your silicon mig brazing is horrible, but your finished product looks great. Congrats. Pretty wife, too.
How come no close ups of your welding ,metal finishing? Almost like your ashamed of your work
Just because you can weld copper with MIG.. does not mean its a good idea to do so. If the apperance is important maybe TIG would do a better job and its problably alot easier too because you get more control and leaves more room to deal with mistakes. You do know why you use MIG/MAG right? Its for increased production, nothing else; it gets the job done faster thats the only benefit. And I think youre actually welding that, not brazing.
i agree 100 %
He didn't weld, he brazed
@@janeblogs324 Alright, just looked as if he got complete fusion on some parts maybe he didnt. It got so hot he even burned holes in it, are you really sure? Definition welding: "join together (metal parts) by heating the surfaces to the point of melting" Definition brazing: "melts the filler material but does melt the base material, does not create a complete fusion" (means you just barely melt the surface). If the base material is so hot, there are holes in it that means you passed its melting point and there should be complete fusion.. can you really call it brazing then? I know you can call a dog a horse but it still does not make it a horse.
It's a braze. Nothing about brazing prevents a base metal from getting hot enough to melt away when errors are made, and I made some for sure
@@42Fab Great so with other words youre improperly using a method called brazing to weld with? I have to assume that your filler material copletely melt together with the base metal if you blow a hole in it. Because, that happens before you blow a hole in it right? Ok I want proof can you cut that piece of thing up so we can have a closer look at the welds. (its a joke dont do it).
