Learn to Weld: Beginning MIG Welding and Metal Fabrication Basics

Buying Tools and Equipment. We re-roofed houses and rewired radios. We built wooden tool chests, skateboards, snowboards, and hockey sticks. We were always working on a wide variety of projects using everything under the sun and all kinds of cold connections like nuts and bolts, screws, nails, glue, epoxy, fiberglass, solder, pop rivets—you name it; we used it.

I grew up into a confident handyman and consummate tinkerer with an appreciation for three-dimensional construction. By the time I started college I was no stranger to creating sculptures, furniture, art, and all sorts of other things using traditional woodworking and cold connection methods.

But then in my first metal sculpture class, I cut into a piece of 11 ga mild steel with an oxy-acetylene gas torch and I was hooked.

Metalwork and fabrication amazed me and became my passion. The way this cold, hard, and seemingly uncooperative material was so easily cut, formed, and manipulated still astounds me. As I learned how to weld, heat, bend, and cut various metals, I could not believe how these incredibly durable materials became as easy to work with as clay. Exploring the unlimited potential of metal work became the compass for the rest of my life. I never stopped welding. After graduation, I moved to Chicago and set up my first shop on the south side, equipped with only a small V Hobart MIG welder and grinder.

Over the years, I moved my shop around a few times, expanded my gear, and worked in a wide range of fab shops, learning as much as I could along the way. Each of them influenced my perspective and expanded my knowledge of metal work, for which I am grateful.

After a few basic lessons in welding, they were asking me to teach them how to make their own bikes lighter, how to weld and fabricate new parts, and how to build custom components. Before I knew it I was teaching community welding classes at my metal studio, Midwest Metalworks. He had realized the fantastic new world of possibilities that I had discovered almost two decades before. Now you can too. If you enjoy working with your hands, learning metalwork will give you a wealth of knowledge that will expand and challenge your ability to create.

There are so many different techniques, styles, and methods to learn in welding, and in this book, I hope to introduce to you the enormous possibilities that come with each one. MIG is just the beginning. It takes time and practice to become a good welder, but I hope through this text you will soon instinctively recognize a good weld that is laid properly. Just like an excellent musician knows when they are in tune or have played a bad note, an experienced welder understands their craft.

The more arc time you log and the more projects you fabricate, the more the world of metalwork will open up to you. It was originally developed for welding aluminum, but was quickly adapted to other metals such as mild and stainless steel. It has become extremely popular amongst all industries from hobbies to shipyard for its ease of use, versatility, and speed.

MIG welding is the focus of this book, but before we dive into it, I wanted to give you an overview of electrode arc welding and some insight into the readily available welding processes out there. How Welding Works There are several different methods of welding. Today, the most common welding process is electrode arc welding. All three types of arc welding use the same three components.

The first and most obvious is electricity, which creates the arc. Each type also uses a filler material, and the third component is flux. The differences between stick, MIG, and TIG arise in how the three of these elements are used to create a bead a bead being the weld that is created ; each type of welding has a different method of execution.

Before we talk about the differences in welders and the methods of execution, we should go over how arc welding works in general. The best way to explain this process is to clearly define the elements of welding and what they do.

Not many people are aware of this, but an electric arc is actually a state of matter called plasma, which is similar to gas. The electrode is an electrical conductor used to complete the circuit, which allows the welding machine to create an arc.

The arc is created by a breakdown of a gas that discharges plasma. Certain gases such as argon, carbon dioxide, and helium have a higher conductivity and ionization that assists in creating and maintaining the arc, making them candidates for a shielding gas.

Make sure to wear proper safety gear. Skin left exposed to the arc light can get a pretty bad sun burn. In the stick and MIG welding processes, the electrode is also the filler metal. When the filler material comes into contact with the grounded piece of base metal, it completes a circuit that creates the electric arc.

The arc forms at the very end of the filler material, which melts into the weld zone, creating the joint. In the TIG welding processes, the electrode is a rod of tungsten. It adds more material to fill the weld zone, feeding the puddle and creating the bead.

The filler metal is usually the same type of metal as the type being welded, but in certain cases, it can be other metals. In the stick and MIG welding processes, it also acts as the electrode. Stick and TIG welding require the operator to manually feed the filler metal into the weld zone. Flux and Shielding Gas The word flux comes from the Latin word fluxus, meaning to flow.

That is exactly what flux does in welding. It helps stabilize the arc and keeps contaminants or oxides out of the weld zone. In stick welding, flux is a chemical coating over the filler rod that burns off, producing a shielding gas that prevents oxidation of the base and filler materials. Flux can be made from a wide variation of compounds depending on the application and material to be welded.

Flux is a component of welding with many jobs to do. The number one job of the flux is to protect the base and filler materials from oxygen and other ambient gases. It creates a barrier called the shielding gas, protecting the arc and metal from outside ambient gases that cause oxidation. It creates a purified environment for the arc to exist in. The flux keeps the liquid metal clean from impurities, also called inclusions, which would otherwise contaminate the metal. And last but not least, it controls the arc, helping the arc come up to a higher temperature to create the puddle of liquid metal.

Flux is most commonly used in stick welding, where it coats the filler metal. When the filler metal arcs to the base material, the flux is engaged. As it burns, it creates a carbon dioxide semi-inert gaseous shield that protects the arc.

This hard shell is usually removed afterwards with a chipping hammer and a wire brush. This wire has the same properties and behavior as a flux-covered stick welder electrode. These machines are not considered MIG welders because they do not have the hookup for a shielding gas.

Shielding gas is an inert gas that takes the place of a chemical flux. It does all the same duties as the flux. The first advantage of shield gas welding is that it has much better control over the arc.

Just like blowing on the embers of a fire, the air pressure not only fuels the embers with gases, but also concentrates the direction of flow. Second, there is no slag byproduct. The shield gas process is cleaner. Third and most important, using a shielding gas makes it much easier to see the entire weld zone while welding.

One drawback is that using shield gas outdoors has a tendency to not work very well. The pressure of the gas coming out of the nozzle can be easily blown away by the wind. Flux core and stick welding are the best options for outdoor welding. The most commonly used shield gases are argon and a mixture of argon and carbon dioxide. Pure argon has great conductivity and heat transfer properties that will assist in creating a cleaner environment for the arc. Pure argon is used in the MIG and TIG processes when welding on stainless steel and nonferrous metals metals that do not contain iron such as aluminum, titanium, or zinc.

This mixture is ideal for carbon steel and will be the focus of this book. The Ground The ground is a crucial part of the power supply.

All electric arc welders use one. In essence, you are creating a circuit, and without the ground, the circuit cannot be created. The ground clamp has to be clamped to the work piece or a conductive metal table that the work piece rests on or comes into contact with. The electrical current feeds though the ground and through the work piece, finding the shortest distance to the electrode as possible.

If there is no ground, there is no arc. Grounding to a conductive metal table allows you to manipulate the work piece easier. If you are going to be working on something large that has to remain on the floor, make sure to ground directly to the work piece. Using nozzle spatter protection will help the tip and nozzle last longer and prevent double arcing. There is a variety of spray spatter protection that can be sprayed onto the work piece.

These products help to protect the work piece from needing to have dozens of little metal balls ground off of the surface. When most people think of electric arc welding, they think of stick. This is a manual feed process in which the filler metal electrode is coated in a chemical flux. The arc forms after striking the electrode to the grounded base metal.

As the filler material melts into the puddle, creating the bead, the flux burns off, producing a shielding gas to protect the arc. A byproduct of flux called slag solidifies over the freshly made weld.

Stick welding can use a direct current DC or an alternating current AC power to create the arc. TIG welding is clean and smooth, but can be difficult to master.
