How Does Welding Work?

June 28, 2023

Welding in its most basic form is simply heating two materials until they melt together, usually adding a bit of extra metal to make the joint stronger.

The most common type of welding is arc welding, which uses a small electric arc to generate the heat for melting the metals. And there are three main types of Arc welding, MIG, TIG, and Stick. While each one is different, they all use an electrode (to generate the arc), a filler metal (to create the weld bead) and something to ‘shield’ the weld from being contaminated by oxygen.

Why don’t school buses have seatbelts?

why dont school buses have seatbelts

School buses are designed in a compartmentalized fashion, that is the seats are close together with high backs, which keeps passengers relatively restrained in a crash, even without seat belts. The NHTSA has spent a fortune studying this, and has found that adding seat-belts doesn’t increase the safety of school buses enough to warrant a full refurbishment or re-design of buses.

Is It True That No Member of The Sex Pistols Could Play Their Instruments?

May 20, 2022

No it isn’t.

Sid Vicious was just as incompetent as you’ve heard, unable to tune or play his bass, but he wasn’t chosen for the band for his musicianship.

The Pistols’ manager Malcolm McLaren fancied that he was making some sort of artistic statement through the look and style of the band as well as through their music, and he thought Sid represented the sort of nihilistic, destructive force he wanted punk to be. Plus he was a good looking lad (under all the hairspray and the sneer) who oozed danger and looked good with his shirt off.

What’s It Like To Regret Having Your Child?

December 16, 2020

I regret having my 9 year old with autism and oppositional defiance disorder every single day. She is very verbal and can be as sweet as a peach when she gets her way, but doing the hard work of parenting her correctly has been a nightmare.

She was an unwanted pregnancy when I was a dumb 20 year old. I was in a lot of psych meds before I realized I was pregnant that I think messed her brain up. I had taken plan B perfectly like on the instructions the one time I had unprotected sex, I figured that would have been the end of that worry. I didn’t realize I was pregnant until she was about 10 weeks gestation and immediately stopped taking my meds but alas. By the time I could get the money together for an abortion (the closest planned parenthood was a 7 hour drive so no-go there) the pregnancy was too far along. I wish I would have looked into adoption now.
