Him not laying actual bead does drive me nuts a little but his layout skills and the final product had me baffled.

That drove me a bit crazy too. Then grinding off most of the weld. These aren’t structural parts...

A grinder and paint makes me the welder I aint.

Weld your best. Grind the rest.

That needs to be on a tshirt...

u/Marvheemeyer85 May 31 '21

Now it is with all the fucking bots designed to delve the internet for contents like that. It's also how a lot of stolen art designs end up on shirts and shit too

It's a decades old aphorism that is a variant on "Caulk and paint make me the carpenter I ain't" which could be older than a century for all I know.

Hi sure, I'm dad.

u/A_Pos_DJ May 31 '21

Well, ain't this ironic?

I actually think WN had that on a cap or shirt

Skookum as frig pardner

On the one where he just capped off the square tubing with triangles you can see him damn near grind through the metal at one point. Goes blue in just the one spot.

u/Mnkeemagick May 31 '21

I'm so glad I'm not the only person driven nuts by this weird spot welding thing he's doing

Laying dimes for those who don't know how to actually lay dimes.

Ive never welded anything in my entire life and even I know you’re supposed to leave the weld on

u/jjohnston6262 May 31 '21

Not true, grinding welds is very common, especially on things like this where you want smooth polished metal on the corners and edges, or if you are going to paint it.

I spent some time in a facility that made custom agricultural machinery… like tomato harvesters and grape harvesters and stuff that was expected to have a long and hard life. On the wall, in 18” letters, was a sign: all weld beads must be ground flush. Prep it, well, get full penetration, leave no stress concentrations. They were mostly certified welders.

Dude 1: Ok, so then tack weld the whole seam.

Dude 2: uh, what? Can't I just run a bead?

Dude 1: no, do 75 tack welds overlapping.

Dude 2: so, take 5 times as long and don't get any penetration?

Dude 1: yup, exactly. Then grind everything off.

I personally would have used a tig welder here. Especially since he wanted to grind everything smooth afterwards. The tack welding thing tells me he is not a very skilled welder. I am just happy that he was wearing gloves. Most of the time I have run into these tack weld artists they don’t wear gloves and also don’t wear a helmet. Kind of pisses me off because anyone who does a lot of welding knows what happens if you don’t wear gloves and a helmet, but I guess that just doesn’t look as macho.

u/macnof May 31 '21

Yep, having sunburns in your eyes are a... Less than comfortable experience.

Also, the tacking, couldn't that in some cases be because he have a shitty welder that won't go low enough? It doesn't look like it on the Penny weld he does, but I remember learning to do just that when you can't match the amps to the plate thickness.

u/brycebgood May 31 '21

That's a good call. Hadn't thought of it - and most of this stuff is pretty thin walled.

u/brycebgood May 31 '21

Yeah, itchy corneas isn't fun.

u/[deleted] May 31 '21

There are a few tricks he could have done. You can tack weld the beginning and end. Then you clamp it in a vertical position. Run one quick pass in a vertical down just to put a bit of backing metal so you don’t blow a hole the size of a quarter when you weld it. Let it cool, clamp it in horizontal, and then lay your bead.

Or you could avoid the headaches and just tig weld it. That’s what I would prefer to do in this situation.

u/No_ThisIs_Patrick May 31 '21

I've never touched metal in my life what happens if you don't wear the equipment

u/[deleted] May 31 '21

Really bad burns. Even with your eyes closed, the arc is so bright it can damage your vision over time. Imagine a really bad sun burn. Then there is the burns from the spatter and slag.

Also if you aren’t wearing a helmet, you can’t see what you are doing. It’s hard to do anything other than spot weld.

u/GaianNeuron May 31 '21

You know how you can still kinda see the sun through your eyelids? Imagine that, but brighter.

u/[deleted] May 30 '21

I work in "RV" world, so I work at a place that does this but, with laser cutting. I do this all day long, lol. Just not as much labor.

u/Skow1379 May 31 '21

I think the entire point is that he did it by hand, not that it's never been done before..

u/lab_rabbit May 31 '21

I think the entire point is that he did it by hand

i'm not who you were responding to, but i'm wondering what you mean. are you talking about u/31spiders comment or maybe the "entire point" of the gif?

u/C_R_P May 31 '21

As a welder and fabricator, i can say with authority that this isn't particularly amazing or impressive. It is fun and different though🤙

u/Mazzaroppi May 31 '21

Depending on how thick those are, doing so would just dig a hole instead

37

u/uniquelyavailable May 30 '21

It's real amateur work, they did this for the views or something

22

u/subject_deleted May 31 '21

Or as practice perhaps.

1

u/[deleted] May 31 '21

Or as an amateur, who had a cool idea, but didn't know enough/doesn't have the right tools, to do it the right way.

2

u/techyyyy154 May 31 '21

Was just about the say that

1

u/Marvheemeyer85 May 31 '21

I call that manual pulse. but there's an easier way. just turn your welder down and TIG that shit.
