here are some industrial welds. i don't think anyone has posted these kinds of pics here before.

All welds were done in position and by procedure using Hobart Fabco XL-71 0.045 fluxcore wire.

2 pass uphand connecting a 1" plate to a 3/4" plate

2 pass uphand connecting a 2+1/8" SCH160 pipe to 1" plate

another 2 pass uphand connecting a 3/8" wall 8x6 square tubing to a 1/2" plate. also shows a circle i freehand cut with a torch (1+1/2" tip oxy acetalyne)

one of the 2+1/8" sch160 pipes welded over another weld, on the left you can see where i didn't chip the flux off the one weld. all are uphand 2 pass welds.

the blue helmet is my flip lid helmet, on the right is my auto darkening helmet, the pole sticking up out of the center of the deck is where my suitcase wirefeeder hangs from. in the background is a truck that is nearly complete.

another angle of the deck i'm working on right now, in the absolute foreground on the left is my ugly homemade tool (it's a tack bar, hammer, pry bar, and chisel all in one, and yes i know it's ******* ugly but it works!!! haha) behind that you see a bessey clamp, and the blue thing behind that is our 500 ton press/brake.
above the deck you can see 2 of the 3 winches that are going on my truck (the one in the background only has 1 winch, so as you can imagine my truck is a expletive of a lot bigger haha)


in this fuzzy *** pic you can see a winch tractor being stripped for its new bed which is being built on the side of the shop that is not shown in the pics. you can see my toolbox, my work bench, and one of the welders behind the truck.

hope you enjoyed the pics. i'll try to get more as we progress on to the more showy stuff like the tig welds

 

Not bad. I remember doing those types of welds in class. Vertical up was my favorite for some reason. The very bottom pass (the one under the cylinder) looks like it could be a little bit tighter but hey....nobody's perfect and Im sure it's a good weld. Where do you work? Im guessing that's where that was taken?

 

it is actually a better weld than the ones that are exposed, it's probably just the angle of the shot that makes it look butterflied (shrug)

yeah these were taken at work and i work at a fab shop in rural alberta. heh, sorry i can't say the name, it might violate the privacy agreement thing.

 

whats the reasoning behind using flux core ?

i've been to a few places here that manufacturer skid mounted equipment trailors all use mig. I actually know a few people that do the same job as you and they use mig. (@ warrior)

is it an engineering spec or something?

 

I wish I could weld vert good like that

 

No ****. I hated vert up when i was learning. I've only done stick vert up though so it might be a bit different. I kanda want to try a mig machine now and see what I can do. Looks good though.... way more consistent than me.

 

this fluxcore has pretty much the same properties as ER7018 welding rod, so we use it for the strength. that piece with the uphand weave of the 2 1" plates is engineered to load drilling rigs on to the truck. things that are incredibly heavy (i don't have an exact number but i think in the neighborhood of 100 ton? i might be way off though)

 

this is not one of our trucks but it gives you an idea of what kind of weight they are designed to withstand.

 

Looks good man. I HATED using fluxcore in class...in fact i hate using fluxcore anywhere But its alot easier to use when youre doing monster welds like this.

Just wondering...why dont you guys spray arc? Drew worked at Deere-Hitachi and thats the process they used. And they did welds that would see tons of stress so im sure itwould be strong enough. Doesnt really matter though cuz the fluxcore will definately get the job done.

I hated vertical up with fluxcore. But i only did it a couple times cuz Hub made me lol. I loved it with solid wire though!

 

it's just a small fab shop that i work at, flux is what we have to work with so it's what we use. it's faster than stick and it works just as well. we do a lot of misc side projects and repairs for people as well as the trucks, but the trucks are our bread and butter. heh

 

first off im a noob and i suck at welding, so dont get mad at these dumb questions.

why is there not too much spatter from flux core. I get spatter like you wouldnt believe. Is it from the verticle metal, so it falls off, or are your settings just dialed in that perfect.

Second, what is your method of welding, it looks like (((((( starting out at the bottom and working your way up correct?

sincerely,

the welding noob

 

Because this flux core machine is far better than the machine you are probably using.

my old instructor works for ZieglerCAT and told us they use mainly fcaw and fc + CO2 - reasons being: it's way cheaper on an industrial scale (millions of cubic feet of argon isn't cheap) and you get more penetration for any given voltage - so you save on gas, electricity, and not having to buy higher powered welders

 

we're using stargold c25 argon co2 mig mix as shielding gas, just standard shielding gas for solid wire as well as flux. works good.

the lack of splatter is because my machine is dialed in really well for the wire and the shielding gas helps as well. and yeah because the machine is a bit beefier than yours (28v & 350amp is what my settings are at and the machine isn't running nearly full duty cycle.)
