Introduction
Welding has become one of the most important trades in the world, and that isn’t likely to change anytime in the near future. So many of the objects people have and need are created either directly or indirectly by welding. If everyone woke up one morning and no one could remember how to join metals, the world would be a very different place by the afternoon.
But welding isn’t just important – it’s also fun. The idea of welding as a hobby is catching on more and more. It’s an extremely versatile skill that can be quite rewarding after you get the hang of it. Something is very empowering about knowing that you can harness some pretty powerful forces – electricity and intense heat – to melt metals and join them together. Even experienced welders get a kick out of the fact that they can take a machine and a few pieces of metal and create something new, functional, and even beautiful. That’s an extremely fulfilling feeling, and I think it’s a product of welding that people don’t always mention when they talk about the trade.
One quality of welding that people do talk about a lot is its usefulness. You can use welding skills to accomplish a lot, whether you want to eventually make a career out of welding or just have the ability to make and fix metal objects for your personal pursuits. Over the years I’ve taught and worked with both kinds of welders, and I know that after they really figured out the ins and outs of welding, they were able to do things that made their personal and professional lives a lot easier.
About This Book
Welding For Dummies helps you understand the basics of how welding works and lets you begin practicing several of the most prominent and useful welding techniques. I walk you through the fundamentals that hold true for all types of welding, and I dig into the details of specific welding processes – stick, mig, tig, and more – to show you how to practice those skills in a safe, productive way. Don’t worry; I don’t have you welding the Statue of Liberty’s torch back onto her hand or anything, but I do hope this book puts you well on your way to achieving the welding goals you’ve set for yourself.
One of my favorite aspects of Welding For Dummies is that you can move around within it however you want and still end up with a huge amount of welding knowledge. You may initially be interested in one welding process but quickly discover you should be reading about a totally different process, and that’s okay – you can jump to that other discussion without worrying that you’ve missed something important. Just beware of paper cuts from flipping back and forth between chapters.
Conventions Used in This Book
Here are a few conventions I use to make reading this book even easier:
❯❯ The world of welding is full of jargon, so I present new terminology in italics and make sure to give a definition nearby.
❯❯ Bold text highlights the action parts of numbered steps and also designates keywords in bulleted lists.
❯❯ I’ve tried to stick to welding standards supported by the American Welding Society (AWS), which is the largest and most prominent welding organization in the United States.
❯❯ All Web addresses appear in monofont. When this book was printed, some Web addresses may have needed to break across two lines of text. If that happened, rest assured that the address doesn’t contain any extra characters (such as hyphens) to indicate the break. So when using one of these Web addresses, just type in exactly what you see in this book, pretending as though the line break doesn’t exist.
What You’re Not to Read
Far be it from me to tell you what you should read, but allow me to make one quick point. In several spots throughout this book, I include sidebars (gray shaded boxes) that contain interesting (and possibly entertaining, depending on what kind of mood you’re in) information that you don’t absolutely have to read in order to understand and practice welding. If the how-to, functional information in the book is the entrée, the sidebars are like garnish. Not parsley, though – I like to think that the sidebars are at least a little more interesting and useful than an herb that tastes funny and doesn’t do much more than crowd a plate. You can also skip anything with a Technical Stuff icon; this information is more technically involved than the basics you need to weld.
Foolish Assumptions
I’m not really crazy about guesswork, but I did make a few assumptions about you as I wrote this book. (They’re all nice, I promise.) If any of the following statements applies to you, this book is for you.
❯❯ You’ve never welded but want to know more about metals and how to join
