A few guys at work wanted to see me weld some cans together. i wire brushed it after that's y i looks dull and like there was no pulse. i shouldn't have it looked real cool before... i'm just so used to cleaning my work.

 

Its better with beer cans, and when there still full.

 

how did you do it so smooth? did you use filler? how many amps did you weld at? i would really like to try this. today i welded some razor blades together. pretty easy. more info please

 

Aren't you supposed to cut the can then weld it?? I thought that was the trick. Either way looks really nice.

 

yeah thats not even the thin part

 

Yeah thats how Ive always seen it done....never seen anyone stack 2 together

 

I've always seen it done like above. <shrugs> Still very good. The smoothest I have seen.

 

X2 ive never seen ANYONE cut the side and weld it. seems like it would be impossible!

 

a guy that had done a weld test at a company that i worked for did a can cut in half and welded it back together.i didnt see it done.i have never felt the need to try it myself.plus i dont have a pulse machine.not that it stopped this guy.what he used was an old miller 400 amp machine the size of a refrigerator.

 

i want to see pics!!!

 

this was in 1997 and i didnt take any pics of it.i knew this guy pretty well and he is one of the best tig welders i have worked with over the years.this was also an aircraft company so he was certified to weld on faa airframes.

 

The positioner helps make it look pretty seamless. Lets see you do one manually.

 

I cut an arizona green tea can in half and tried doing a butt-weld. I had my machine set at like 6 amps or something ridiculous lol. After a couple tries I got one or two tack welds but never a bead lol.

 

my machine only has three programed start modes its on the softest now and i know it would blow a hole in it as soon as i strike an arc at like 2 amps.

 

It is possibile to weld it cut in half, but the cut and setup has to be perfect. The cutting is the hardest thing to do and get it perfectly even. Where i work we weld as thin as .0009 thick stainless, titanium, inconel and a few other exotics for the aerospace and medical field. Yes i mean less that 1 thousanth. And yes it is done under a microscope. Id really like to see some pictures of someone who has done the can weld after cutting it in half. Ill give it a try this week and let ya know how it goes. But thats got to be really hard to do. Thanks for all the feed back.

 

Ill take a pic the next time Im over at my welders shop, the can was completely cut in 2 and the can now holds water... hes ****ing awesome, and hes always got some kick *** project going on so its cool to hang out and watch/get in his way

 

I cut a can in half today to take a measurement.. It mic's roughly .0045. It is weldable however you need a machine with very specialized controls like start current, fully adjustable high freak, and the ability to control heat with pulse width and pulse rate. The machines I use can run at a 10th of an amp and they are VERY expensive. If there is someone out there who can do that weld by cutting the can in half and welding it back together with out special equipment for welding and cutting it Id love to see it. Never mind holding the thing in place with out a fixture... Cans are rigid until they are cut hahaha. It would be very difficult to do with out that stuff and the use of a positioner.

So lets see these pictures and what equipment they used.


And for the other guy that asked... A good general rule of thump is that it takes about 1 amp to weld 1 thousandth worth of material, depending on the material and about a million other things.

 

Ill ask what equipment he used too....and Ill even take some pics of the plenishing hammer he built....its one big bad ****

 

I did this already, but I threw it away, I'll weld up another when I get in the shop in the morning. Last time I did it I blew some holes in the thin part and had to fill it, so you could weld the center, but you can't get it clean enough. I'll try both.

 

heres my take on doing this by the side. take 2 beers. dont open them. take a wire brush and clean them. put clean gloves on. chug them. cut them(some how) then weld them. bam! that fix's the problem of cleaning the sides without crushing them. so.. lets see it! i cant even do the bottom of them yet. my welder only goes down to 10amps. BUT i can do it if i had some 1/16th filler. the 3/32 is to hard IMO. so again, lets see this!!!

 

Randy RMF posted his can i think a while ago and the razor blade one too can't find pics now though

 

I did a couple of razor blades a little over a year ago on a Lincoln square wave 350 when I was just starting to do fab stuff. I tried to do it last week on my Sync 500 but even the lowest current I can get from it is too much, melted like half the blade away instantly. I would try again but we're running low on blades

 

Sharp edge to sharp edge...no overlapping either!!

The razor blade thing happened about three years ago on here. RMF posted some. I tried but had trouble, then he gave me some tips by PM. Anyone saying it's easy...well, that's dependent on perspective. Once you know how to do it...it's fairly easy yes. Trying to get to the point of doing it though..ain't so easy.

Clearly more expensive machines are going to make that job easier as well.

I have some blades with a perfect bead...my boy took it to his work though. 20 year TIG welders at his work didn't believe it could be done, so he took it to them. Granted, TIG'ing for 20 years didn't mean much with these guys, cause their stainless welds I saw were garbage. Point is, I never saw my blades again though.

 

ive been tig welding for about 2 weeks and i fusion welded 2 blades by the tips together. pretty hard. went through like 10 blades trying. no way i could add filler lol

 

What kind of blades did you use? This kind?
