In fifth grade a boy tried to impress me by swallowing a whole tadpole live and I punched him so hard that he puked and the tadpole was fine.

First off: unbelievably excited about Sun-Spider, AKA Charlotte Webber.

Second, my multiply-disabled chronic pain ass has zero patience for any of the fuckers who are talking shit about the concept (including people who say that someone who uses a chair part of the time is 'faking' and acting like this makes it bad rep when disabled folks have been telling you for decades that there are ambulatory wheelchair users).

third holy fuck i need both her dress and costume

Do a DannyMay crossover AU draw! Personally, I'm playing with Danny getting mistaken for a Witcher in my prompt rendition of the Crossover prompt, but do whatever makes your heart sing!

👀 or... if you want,,, what about a Danny in Wonderland crossover with him chilling with the Cheshire cat

Oh my friend you don’t understand how much I love Wonderland so played with some ghost zone wonderland Tea party kind of vibe I am so sorry this took so long

Ooh first time ever pipe welding

A little too hot but not horrible

Not even once

Friends don't let friends weld globular transfer

I need a new job

How does welding work? What’s the stuff you use to bind the metal and how do you get it on the metal?

Fortunately I am a welder on this blog! (I mean I’m the same person running both blogs but hey! I do what I want

Ok, so first thing is what’s welding? Basically if you have two things you want to weld together you melt them where they meet, and sometimes add filler, which melts in to fill the gap (but sometimes you don’t need it) and the two things become one thing. You can weld lots of different things, like ice (a fun little project you can do in your kitchen, useful for ice sculptures) and plastic (although epoxy is easier and more reliable) and, of course, metal.

This is different from glue where you start with two things and glue, and you end with two things and glue, but they’re stuck together. Welding starts with two things and filler, and ends with one thing, because you melted the base material and filler, and fused it all together.

Now for how to weld metal (below the cut)

So the two most common kinds of welding are arc welding (split up into consumable electrodes, and non consumable) and oxy-acetylene welding (aka gas welding), and there’s 4 manual kinds of arc welding: stick, mig, flux, and tig, and they all weld in different ways, but the basic concept is heat up the metal until it melts, add filler somehow, and keep it clean (getting rid of oxygen is a big part of welding).

Basically you keep a weld clean by using some sort of shielding, stick and flux use flux (wonder why they decided to call it flux welding), and mig and tig (and sometimes also flux) use gas (usually argon) and that pushes away the oxygen and other air so the weld doesn’t get contaminated. You can weld in a vacuum, (like in space) without shielding, but most people weld on earth so shielding is easier.

Ok, now for welding with a consumable electrode. This is stick, mig and flux welding. The electrode and the filler are the same thing. When the electrode touches (or get’s really close to) the base metal, it creates a really hot arc or electric spark (kinda like when you zap your finger on the doorknob times a billion or something) This heats up the electrode and the base metal so much that they melt, and the electrode kinda explodes, and shoots metal down to the base material.

Now how do you get filler to the arc? Mig and flux welding have a spool of wire that comes out of a gun. You pull the trigger, and the gun shoots wire out and you weld. It’s kinda like a hot glue gun, if the gun used wire instead of sticks. Because you can use really big spools (the ones we use at work are 16 pounds) you almost never have to stop in the middle of a weld because you ran out of filler.

Stick welding uses a stick electrode instead. So you clamp the electrode in the stinger (what the electrode holding clamp is called) and then when you strike the arc, you move your hand closer to the weld as the electrode gets shorter. When your electrode gets too short, you stop and grab a new electrode. Sometimes this happens in the middle of a weld, which isn’t ideal, but you just have to deal with it.

via GIPHY

Stick welds and mig welds can be either oscillated or not depending on the application, so sometimes they have ripples, and sometimes they don’t.

Finally we have torch welding. Tig welding uses a non consumable electrode, and is mostly the same as gas welding because of it, only using electricity instead of fire. Even though it doesn’t use fire, the business end of a tig welder is still called a torch.

via GIPHY

You can see the electrode (the big orange part) the arc (the shiny white part) and the filler being added really well in this. If you substitute the electrode for a flame, then you’re gas welding. Think a blowtorch. You use the torch to melt the metal, then you hold a rod of filler in your other hand, and dab it into the puddle made with the torch. It all melts together and you get a nice little weld

Usually torch welding ends up looking like little beads, because you have to dab the filler in to get a proper weld.

And there you go, a very beginners guide to how to weld. And if you’re like wow, I didn’t know any of this, don’t worry, it took me a couple of days before I knew any of this either.

Just a little restoration project I’ve been working on this week. Finally finished painting it up

Gee I wonder if I got enough penetration lol

Me: everything will be fine as long as I don't touch anything

Me literally 1 seconds later: *touches*

As much as I like my shirt pockets I do wish they would stop stabbing me!

My welds also come in right handed oscillation

[Photo: an outside corner mig weld that's oscillated in a circular pattern. The weld is clean but the soot hasn't been cleaned off yet]

Beautious

[Photo: an outside corner Al mig weld before the soot has been wiped off. Despite the soot on the box the weld is clean]

I just made a song

Collet body, shielding cup, collet, tungsten, electrode cap

Bestest song ever
