mormanman Posted October 26, 2008 Posted October 26, 2008 WW, do they hold? And another thing I think is funny is if you've ever looked under a school chair (the blue ones) the welds are awful. I think its funny. But they hold. So? Depends on your definition of good.

marks265 Posted October 26, 2008 Posted October 26, 2008 http://img360.imageshack.us/img360/1678/27518668gp8.jpg Warez, It looks to me like you have the heat about right. I think your problem is how you are holding the rod. You may want to try washing the rod back and forth a small bit so that it does not look so cold at the bottom of that particular weld. If you don't weld every day it will be hard to get that 1st class look you're looking for. IMO that almost looks to me like a 7018 weld. Each rod is usually printed with which type of rod it is at the electrode holder end. Overall I think ya did good
tentacles Posted October 26, 2008 Posted October 26, 2008 Hell, it's hard to get a 1st class look with any kind of stick weld, without a good inverter welder and serious practice/skill. The problem may be the 60xx series rods, they aren't terribly good though how strong does this need to be? No wire machine there?
WarezWally Posted October 26, 2008 Posted October 26, 2008 (edited) Because the square tube is relatively thin I dont have much time to build up a large bead as it will cause distortion / blow through. The things I dont like about these fast freeze rods is that I have to weave it up and down in the joint with 7018 series I could just drag it and the bead would look much better.

mike_au Posted October 26, 2008 Posted October 26, 2008 I'll have the be careful not to get too close when I get pictures of the mill I'm putting together. If you are criticizing those welds then I wouldn't like to hear what you have to say about mine
tentacles Posted October 27, 2008 Posted October 27, 2008 mike: I think he's mostly referring to the butt weld there, not the fillet. The fillet looks fine though with perhaps a bit more material than strictly necessary.. but more is better than not enough, and perhaps most of the load (whatever it is) will be in that direction. My question, though, is why not stainless steel? Shit's cheap now as scrap/salvage, we're only giving .10/lb for it.
mormanman Posted October 27, 2008 Posted October 27, 2008 My question, though, is why not stainless steel? Shit's cheap now as scrap/salvage, we're only giving .10/lb for it.Probably b/c Stainless steel you need TIG for. Correct me if wrong but I'm pretty sure. TIG or Oxy, they're like the same almost (I do know the difference BTW) but TIG and Oxy is almost gone. I don't know anyone that can TIG but one that can Oxy.
tentacles Posted October 27, 2008 Posted October 27, 2008 Naw, you can stick, MIG or TIG SS. You can use oxy to silver solder or braze it if you have the right solder/braze. Stick on SS can actually make some very nice looking welds.
Bonny Posted October 27, 2008 Posted October 27, 2008 Started to weld up a few lab stands and the welds are utter shit, I'm fairly sure its the 6013 rods that I have. Couldn't find any 7018 rods in the store so I grabbed a box of these hoping that they would be ok. shit shit shit shit Unless you are just learning, or tacking maybe, throw the 6013's (farmer rods) away...total garbage rods. They will work but leave an ugly finish and are not very strong. I would say after looking at your pics to go with a smaller rod. The bead size is much larger than needed. To avoid burning through, use a whipping motion, moving ahead of the puddle and then back into it, allowing it to cool a bit before adding more material. Hell, it's hard to get a 1st class look with any kind of stick weld, without a good inverter welder and serious practice/skill. I'd have to disagree here, if you know how to weld and do it correctly, IMO, stick welds are nicer than MIG welds. An inverter is not needed, just a machine that delivers a nice DC arc, AC arc welders are crap. Stick does take WAAAAY more practice though, where MIG can be reasonably learned in a matter of hours. @mormanman: You don't need a TIG for SS. Stainless can be welded with a MIG and arc welder as well as TIG. Stainless arc welds are very beautiful, and take a concave shape. Also SS arc welding rods can weld unlike materials, carbon steel, SS and they will even (somewhat) bond with cast iron.
WarezWally Posted October 30, 2008 Posted October 30, 2008 (edited) I was eying a nice DC inverter at the hardware store, could have gotten it for a decent price too but I really want to either get a TIG or oxy set. Sucks that its impossible for us to own our own bottles and the rental is expensive. Edited October 30, 2008 by WarezWally

Almost any TIG you may buy should have stick welding capability. That's shitty if you can't buy any bottles though.
WarezWally Posted October 30, 2008 Posted October 30, 2008 Argon is about $60 for a med sized cylinder and rental is about $15 per month.
Bonny Posted October 30, 2008 Posted October 30, 2008 Argon is about $60 for a med sized cylinder and rental is about $15 per month. The rental is the real killer...unless you are going to do a lot of welding and won't have the bottle around for long.
tentacles Posted October 30, 2008 Posted October 30, 2008 Wally: You aren't ALLOWED to own cylinders?! Here it isn't easy, but you can do it. I own my CO2 and my argon cylinders. The real trick is finding some place that will fill the cylinder with the mix you want. CO2 is easy, because fire extinguisher places will fill em cheap. But argon (or god forbid, a mix!) you've gotta go to the places that fill them and talk to, generally, the manager. Phoning will get you a sales rep that is keen to lease you a tank. I own my argon tank for less than a 3 year lease would have cost (for a smaller tank!). Using 80cf of argon/2% CO2 will likely take me the rest of my life, lol. It's absolute shit if you are legislated away from owning a tank. Some nanny state garbage, I expect.
Swede Posted October 30, 2008 Posted October 30, 2008 That IS bullshit. Can you own a SCUBA tank? Same deal, pressurized gas at 3,000 PSI+. If anything, the SCUBA cylinder is more dangerous, because they are built lighter, and thus are a bit weaker. One thing to watch out for when you own a cylinder. It might take years to go through 3 or 4 fills, and eventually there is usually a periodic inspection (visual + hydro test) that the cylinder must go through before it can legally be refilled. No biggie, but it is part of the cost of ownership. I've used nothing but argon so far for TIG. I'm not a certified welder, and I'm not welding airplanes or any other critical application. If I were to have one welder, I'd choose TIG... unless your goal is welding fences, trailers, other large projects. TIG is slower than other processes, but it can do it all, and is very clean. You can TIG weld in your living room if you wanted to. BTW TIG fill is also numbered... it's not just stick that carries a numeric designation.
rocket Posted October 31, 2008 Posted October 31, 2008 Sucks that its impossible for us to own our own bottles and the rental is expensive. Did you go to BOC? I went there a couple of months back to look at getting a O2 bottle refilled but to be tolled no one one can buy/own a cylinder. For the amount of time I would use Oxy it wasn't worth renting the bottles. $140 for the year BTW then the gas on that.
WarezWally Posted October 31, 2008 Posted October 31, 2008 There is nothing stopping you legally from buying your own bottle but nobody will touch it let alone fill it, it will be a very expensive doorstop. There are 3 company's that sell industrial gas, none of them will allow you to own your own bottle, they spin some bullshit about safety but when push comes to shove its all abut money and they can make more off rental. I would love to have a TIG and oxy fuel set but the cost is insane.
Bonny Posted October 31, 2008 Posted October 31, 2008 If I were to have one welder, I'd choose TIG... unless your goal is welding fences, trailers, other large projects.

BTW TIG fill is also numbered... it's not just stick that carries a numeric designation. If I has to choose only one welder, I'd definitely also go with TIG, but ONLY with a machine that can also do stick welding, which is my favorite...especially if doing anything outdoors, no gas to blow away. MIG is by far the fastest welding and easiest to learn though, and you can weld Al and SS with fairly well with it too.
mormanman Posted October 31, 2008 Posted October 31, 2008 Man I hate being sick and sore at the same time. I also hate doing PT with the Marines. My God if you have insomnia join the Marines for a "fun" day of PT. I got home after an hour of that shit and dear lord I was out like a light being hit with a hammer. I slept like a baby for 14 hours.
WarezWally Posted November 2, 2008 Posted November 2, 2008 (edited) A bunch of racist fuckwits turned up to work today, realized I was going to get an earful as soon as I saw their car bonnet. Damn shitty neighborhood Edited November 2, 2008 by WarezWally
TheSidewinder Posted November 2, 2008 Posted November 2, 2008 If I understand that picture correctly they'd be ultra-nationalists maybe, but racists? (Or was that just the beginning of their ignorance?)
Richtee Posted November 2, 2008 Posted November 2, 2008 as I saw their car bonnet. Heh...sure they weren't gay activists? Who else would have a bonnet on their car? ;{) I love the variations in language...SOO much fun to be had!
oskarchem Posted November 9, 2008 Posted November 9, 2008 (edited) My mom just made me stop pyrotechnics.... One flowerpot too much (But god was it loud. Loudest thing I've heard, well maybe my salute shell was louder)... I'm so depressed, this is seriously going to be a big change. I've been doing this for the past 3 years... Not that I'm a big pyro that can make flawless 8" double petal shells, but still, I liked making fountains, small toilet paper shells, etc... My god I'm pissed and at the same time depressed... At least I can still fly... Edited November 9, 2008 by oskarchem
elstevo Posted November 9, 2008 Posted November 9, 2008 Stop pyro...Dude that totally sucks, im sure there was a loophole in what your mum said, my mum doesnt mind me doing the hobby as long as I dont get hurt, though a year and a half ago i burnt all the skin off my hand with pyro stuff. Id be gutted if i had to quit pyro... Id feel empty... Come fly down to Australia make some shit in the desert!
