Читать книгу Welding For Dummies - Steven Robert Farnsworth - Страница 14

The difference between fabricating and repairing is simple. When you weld to fabricate, you’re making something new. When you weld to repair, you’re welding on something that already exists but needs fixing or modifying. Repairing can be as simple as welding to fix a tine on your favorite old rake, or welding to fix a crack in a helicopter fitting assembly. (Of course, I lean a lot more toward rake repair than helicopter maintenance in this book!) Although metals are durable and tough, they do break down because of damage or repetitive use, and when that happens, welding is the best way to fix them.
