Do you love power tools, an open flame and working with your hands? If so, welding just might be the job for you. A longstanding type of craftsmanship that allows you to create custom, functional items or repair a wide variety of machines, it's a rewarding yet challenging career path. If you're just getting started, the jargon and complexity of welding can be intimidating. It's also a pursuit that can come with plenty of risks if tackled incorrectly. Here are a few important basics to help you get started with confidence.

Understanding the Basic Definition of Welding

If you're interested in pursuing welding, it's important to understand precisely what the craft entails. At its most basic form, welding involves using heat to attach pieces of metal together. Though you'll eventually learn what all the welding symbols and welding cable specs mean, getting the foundation down first is the most important step. Put simply, welded metals are heated until they reach their melting points. Then, they're combined into a cohesive unit. As they cool, a permanent bond forms and a new object is created. Unlike other types of bonds, including soldering, once a welded bond is created, it's virtually irreversible.

MIG Welding at a Glance

If you're just starting out in the welding world, you'll likely begin by performing metal inert gas, or MIG, welding. As you research welding for beginners, this is the most common practice you'll come across. This is a form of electrical arc welding and is sometimes referred to as gas metal arc welding, or GMAW. When you perform MIG welding, you send an electrical circuit through the objects that you intend to weld via a welding wire. Acting in this case as an electrode, as the wire touches the metal objects, the circuit is finished. Then, the welder pulls the wire back slightly, and in turn, an arc is created. This arc can reach incredibly hot temperatures of up to thousands of degrees. As a response, the wire melts completely, and the metal objects melt only partially. As the three three metal materials cool, a bead forms along the seam where the two original metals are welded together. The welder then continues along this seam, adding more wire from the welding gun every time a piece melts away.

TIG Welding

More experienced welders can perform TIG welding, which is similar to MIG welding but with a little more complexity. If you're new to the craft but are still interested in learning about this subform, you can look into resources that detail TIG welding for beginners. Instead of using a consumable wire, a TIG welder operates a welding gun with a tungsten metal rod inside of it. This is the electrode, in this case. The welder holds the gun in one hand and feeds a filler rod through in the other. As the intense heat fires up, it melts the filler rod, which is continuously replaced. The welder can adjust the electrical current in TIG welding by controlling a foot pedal. In both TIG and MIG welding, the welding gun releases a gas that protects the metal materials from outside contaminants in the air.

Safety Equipment Required

While there are other forms of welding, including stick welding and flux-cored welding, MIG and TIG are the most common. To this end, you'll need to to select the correct type of welding gun depending on the process you intend to perform. You'll also need to purchase a table for welding and a sturdy welding helmet. Protecting your face and eyes is critical, as the heat and light can be permanently damaging. Durable leather gloves and shoes are also required. You may want to invest in bib overalls or aprons to protect yourself from sparks. As you suit up and prepare your materials, be sure to practice with safety and security in mind first and foremost. Welding can be an interesting and enriching hobby or career, but it can turn dangerous in a second. Before you begin, read as much as you can about the topic and watch a few professional welders in action. Soon enough, you'll be creating your own custom pieces to admire.
