Metal Fabrication

[Ramathorn15]

I’ve heard of contaminated gas or impure gas. Cylinder mishandled prior to fill? Saw some post where a dude was comparing airgas vs praxair or some other mix of suppliers and the difference was evident.

It's Matheson gas. I havent noticed the issue with the first half of the tank, but I don't remember if I did any grinding.

I kinda want to start making a grill. lets design one

what dont we like about this one?

I need one of these, I'll give you measurements.

The cost of steel is so high right now, it would probably just be cheaper to buy one.

Should start coming down soon

Ugh. Dealing with some random small porosity in the roots my welds. I've never had this issue before but of course it starts when I'm trying a production run. Only visible when I round off the weld.

I've tried:

Turning my gas up (all the way up to 40 scfh)
Cleaning surface more than usual
New tip and gas gas shield
Checking/greasing my orings and lines
Switching between push/pull
Shorting my stickout

Nothing's working. I'm suspecting that it's either bad wire or there's a leak somewhere that I haven't found.

Do you have a gas flow meter for your nozzle? Like this?

No. I need to get one. My tank is getting low so I'll grab one when I go fill it..

Yeah bottle regs can be off and too much gas will give you porosity.

also just get a spray bottle with dishwashing liquid and water and spray your gas connections and see if any are leaking

Also wind can be a fucker, something you might not think is strong can be an issue

gas at 40?

what kind of lube did you use?

Not in this crew, but I’m on episode three of Metal Shop Masters on Netflix and I’m digging it so far. A lot of creative talent and Jo Koi is the host…which is weird but cool.

Rae is pretty hot in a weird dirt ball kinda way like pump her outhouse behind a tractor type of weird

Long time no talk my dudes. I did a thing. Some how I convinced the ministry of finance to let me build a buggy. So I bought a frame.

Thought it was wind at first. So I closed the garage and did some beads but no difference.

Agreed

Cut back the front body mounts on the 4Runner over the weekend. MIG welding inverted was a bit difficult. Was able to finish without melting the bushing though.

I was having some issue's with porosity running dual shield. Ended up replacing the liner because it worn horribly, haven't had an issue since. So, maybe your liner is wore out and giving you fits.

If you’re having trouble with overhead, turn your amps down a little bit

I'll try and remember that for next time.

Overhead and vert up the pool can fall, so you usually run them lower, normal position it’s falling into the job

For anyone fabricating in a tight garage, is there a safe method? Would be worried of some rogue spark getting near an ignition source. Would like some sort of metal cabinet. Was thinking of converting a section of my metal costco shelving unit.

Use fibreglass fire blankets, and get a god damn exhaust fan to get the smoke out

Tig. Problem solved.

 

[PleaseEatSomeShit]

I dunno I’ve been cutting, grinding, and welding near all sorts of flammable shit in a tight two-car.

I’m amazed that I’m still alive tbh.

 

[PleaseEatSomeShit]

Finally getting around to doing something with this thing.

Raw steel is expensive as fuck. I can’t afford to finish this thing out as fast as I hoped.

After spending the last month or so chasing the porosity issue with no luck, I finally decided it's miller time.

Millermatic 211



Basically the same machine as the HF Vulcan I have but at least now I can get any replacement parts.
