In today’s Welding Wonder Wednesday we look at the giant geosphere in Epcot: Spaceship Earth.
Constructed in the early 80s, Spaceship Earth was one of the largest structures ever created by WED Enterprises. The project engineer, Jon Hine said “building Spaceship Earth was like putting up an erector set —we just kept adding one piece on to another.”
Although the structure looks unusual, the welding techniques use were the same as those used in standard construction projects. Because of the large amount of shop welding required, semi-automatic submerged arc welding was used for the full penetration weldments, and fully automatic submerged arc welding was used for the plate girder fabrication. In order to ensure the most perfect welds, radiography, ultrasonics, magnetic particle, and penetrant inspections were all used for precaution.
To this day, Spaceship Earth still stands as one of the most impressive structures at Walt Disney World.
In this week’s Welding Wonder Wednesday we look at the Pratt & Whitney F119 Engine.
The F119 is considered by many to be one of the most advanced military engines ever built. Pratt & Whitney designed the engine to power the F-22 Raptor. When speaking with the American Welding Society in 2001, Tom Farmer, Vice President of the F119 Program said “One of the breakthroughs of the F119 is its hollow fan blade and integrally bladed rotor design, which result in a lightweight, durable, high-performance product. This concept could not be provided without the use of advanced welding techniques, such as linear-friction welding and diffusion bonding.”
The F119 represents the first time the linear friction welding process had ever been used in a large aircraft engine. It powered the Raptor as speeds of Mach 1.5 or greater.
In today’s Welding Wonder Wednesday we look at the external tanks which helped carry the Space Shuttle into orbit for 30 years.
In the early days, the tanks were welded using gas tungsten arc welding. Lockheed Martin and NASA developed the variable polarity plasma arc welding process. The process created a keyhole in the metal and the molten metal then solidified at the back of the hole as the torch progressed. In later years, NASA began using friction stir welding to manufacture the tanks.
Talk about the ultimate romantic gift - for a welder, at least.
This picture of a steel rose was posted on a reddit with the following story:
"I got married a couple of weeks ago and my wife told me that some woman had made up a rule where you’re supposed to give each other something sentimental on the day of the wedding. This was very stressful for me because she already has everything so she is very difficult to buy things for. Throughout our dating relationship, I would randomly buy a single flower for her (usually a rose) just to remind her that I cared about her and I thought about her even when I wasn’t there. Since my little brother works for my dad in a welding shop and apparently has all of the artistic talent in the family, I asked him to make her a flower that would never die…out of steel. This is what happened."

It’s not quite welding, but we thought this video of a dude forging a knife with some nifty metalworking skills was pretty cool.
This inspiring photo comes from the Industrial Welding Academy in Houston, TX.
A reddit user said the man in the photo was a fire lookout who wanted to be something more. The director of the Academy took him under his wing and taught him how to weld. As you can see, his disability is not holding him back.
It just goes to show you - there are no excuses for not following your dreams.
In our bid to be the world’s premier organization devoted to welding and allied joining and cutting processes, we need to be aware of technology needs worldwide, as well as locally. While AWS will continue to have a strong domestic focus, we also need to be an effective player in an increasingly global economy.

How many of you have actually seen the cover of the very first issue of the Welding Journal? Well, now you have.
It was first published in October 1919, but because of the expenses needed to sustain a continuous publication, it was discontinued after the very first issue. It wasn’t until 1922 that the Journal came back into existence thanks to advertising revenue.

We here at the American Welding Society are big fans of the manliest man on television: Ron Swanson. And it’s an honor to know that even he worked in the manufacturing and metal forming industry.
That should make all of you feel even more proud of your job. Now you must honor Mr. Swanson by growing out your own glorious mustache.
This is what you get when you combine a love of welding with a love of miniature railroads.

How many of you bring your love of welding home with you and do projects like this?
