Post a pic up of your best welds

[Roadsailing]

because i have no life lol and just like sharing shit with you guys :D

if you can find some metal discs roughly the size of 20 cent coins you can make some nice cubes/other shapes for not much money...

If the details are correct, the car running this setup ran a 10.something second pass.
Mind blown

Also puts all the welds in this thread to total shame.

i'm imagining a long diarrhea sound accompanying each bead, I've definitely done worse though.

^^ straight from sloppy mechanics!!! some of their shit is funny, scary and some just works

not mine, but had to share

That could well be your problem, the fixed shade 11, I typically now use between 9 and 10 for the normal low to
mid current MIG and TIG I do, especially with steel or stainless. Aluminium, where the amps might be up around
170-190 I would use 11 maybe 12. And when doing really thin stainless I may be down to 15-30 amps and use
7 or 8.
As I have got older I am pretty sure the sun has got weaker. But as others have said, good working light or
helmet light can help too.

Ok I'm even more confused now. I changed over the gasless wire, change polarity etc, as I ran out of solid core wire.

When welding I noticed I was getting the nice sizzling type noise when welding I never really got when using gas. Not much splatter, and I could actually get a half reasonable weld.

Why is this? Its like the shielding gas is doing nothing.

Gasless wire or any kind of Fluxcore will weld much different.

The profile of the wire and the additives with the flux give a higher deposition rate than solid wire. The downfall is less penetration into the parent metal.

[snavy]

Yeah but I thought gas welding gives a better weld? I've used gaslesss only a couple times before I got gas.

Either way why can I get that nice stable sizzling sound without gas, never with gas its not as stable and seems to splatter more? Its like I never can adjust the welder properly with gas?

Let me guess...little 220V 140A hobby shop/home store welder?

They simply aren't made to really "run" gas, they're optimized for flux-core wire and can't really push the power that solid wire needs. Not really that they can't provide the current, just that the voltage regulation isn't as good as it really should be. The flux-core wire has less metal in it, so it melts faster, plus the vaporization of the flux core helps get more heat into the wire. Deposition rate goes up for the same current/voltage, so wire speed has to go up, too. Also, Flux-core is configured (normally) as Electrode-positive. This also heats the wire more than it heats the base metal.

Now, as to why the penetration is *better* with gas welding, is because gas-shielded MIG welding is done with Electrode Negative polarity. In this configuration, the heat is focused on the base metal more than the electrode metal. The most heat energy is transferred to the weld puddle in EN, and this hot puddle melts deeper into the base metal. When the polarity is switched to EP, (as is used with flux-core wire), then the major part of the heat energy is focused on the electrode, and this makes the weld puddle cooler and less penetrating than on EN, Also heat energy is dissipated through the electrode into the shielding gas and electrode holder.

Ah I have a cigweld 150 Mig. So bigger mig is required!

Thanks for your help!

Isn't the electrode polarity the other way around? My manual tells me when using gas to have the electrode on positive, its reverse when gas less wire is used.

Did some welding this week:





And made a collector this arvo


I still need to work on my out of position stuff.

[Nacho]

Tidy!

Good old Hardox, the poor mans armour. 450 in 4mm is good for most handgun rounds up to .44 mag.

Remind me if I ever try to kill you to stab not shoot.

[Commotion]

We are using 6mm Hardox. I like trimming a 4mm piece of the edge of some scrap and giving it to people to try bend with their hands. It blows their mind how strong it is.

[Gin Kii]

6mm Hardox 500 will defeat AK-47 .

man I've fucked some drill bits drilling that shit and bisalloy
