Metal has been mined by humans for thousands of years. Over time, the technology and techniques used to produce and shape metal parts have been driven by innovations in science and technology.
What Do You Need To Start Welding
Before we dive into some of the technical processes available for metal welding, let’s first take a moment to define welding. Welding is a manufacturing process that joins materials, usually metals or thermally, by fusion. Fusing materials are distinctly different from other methods of low-temperature metal joining, such as welding, which do not melt the base metal.
The Ultimate Guide To Tig Welding
Welding is the joining of two metal parts to create a solid continuous piece. All welders work on the same principle: A gas torch or electric welder is used to produce precise heat to the fusion material, and the operator inserts filler material to complete the fusion.
Over time, innovation and accessibility have come and now we have come so far that you, yes YOU! – can learn to weld easily. Let’s start!
This class is designed for those who are completely new to welding. In this course, hobby metalworkers will learn ideas and tips on how to become skilled welders, ready to take their crafting to the next level.
I learned to weld in college when I took graduate sculpture classes while building my thesis project. I mainly learned oxy-acetylene welding to do very fine wire work. To this day, I still think Oxy-welding is my favorite technique, but it’s not practical for all applications, nor is it as fast as MIG.
Metal Inert Gas (mig) Welding
I learned MIG welding when I was learning bike repair in Reno and my neighbor handed me the gun on his 110V flux cored welder and said, “Okay, now you do it.” I explained that I had never used a MIG welder before and they turned to me and said, “It’s like using a really hot glue gun.” This phrase removed any fear I had of doing a bad job and I was confidently holding the torch within 20 minutes.
I have taken on large structural welding projects and done structural welding on sculptures that have traveled the world.
Bottom line, I’m not a professional or an expert, but I’m self-taught, experienced, and can offer you a great way to get metalworking and welding in no time.
MIG welding can be safe as long as you follow some important safety precautions. Welding requires us to protect ourselves from many dangerous aspects of the trade with safety equipment to prevent ourselves from getting burned or blinded.
The Fascinating History Of Welding: The Evolution Of Welding Technology
A self-darkening welding helmet protects our eyes from the light produced by any kind of arc welding, but allows us to see when the arc is not active. Self-darkening helmets are useful if you do a lot of welding and don’t want to take the helmet off and on to see what you’re doing between welds.
If you work in a crowded community shop, shield others from seeing the arc by using a welding shield. The screen protects potential viewers from being blinded by the arc.
It is necessary to cover the skin. When you start grinding and welding, hot sparks and molten slag can shoot in all directions. We protect ourselves with heat-resistant leather and natural fibers; synthetics melt instead of burn, meaning they melt and burn into the skin, yay! But honestly, a leather jacket is too hot for any prolonged welding project. If you are like me and heat up quickly, you can try a welding apron with a long sleeve flame retardant cotton shirt.
Most of the time I wear dresses that have been rated for use in welding. They cover the entire skin and I can tuck the sleeves into the gloves when I’m welding, or easily roll them up when I’m grinding. This cover will not only protect your skin from the heat generated by welding, but it will protect it from the UV light generated by the welder’s arc.
Essential Welding Tools And Equipments [pictures & Pdf]
Like your welding clothes, you’ll want to wear heavy-duty work shoes that don’t have synthetic materials that can melt. A good pair of work boots or even trainers are fine, just no running shoes.
If I’m going to be boiling for more than 15 minutes, I’ll even put on sunscreen. I have occasionally gotten a sunburn on my neck due to the small gap between the leather and the helmet, but the SPF 110 seems to do the trick.
When you’re welding, you’ll be holding and sliding your hands and forearms over very hot metal. For this reason, we use MIG welding gloves. Note that MIG gloves are the most uncomfortable in the world. They should be loose so that if they get too hot you can quickly throw them from your arm to the ground.
Using a sanding visor protects your face from flying particles while using a grinder. If you are working on cutting paint or other types of metal finishes, consider wearing a face mask to protect yourself from potential fumes from the steel coating.
Troubleshooting Weld Defects To Save Time & Money
I wear safety glasses under my welding helmet for the sole reason that I make sure to wear them when I start grinding metal. There are some horrible horror stories about metal slag and debris coming into contact with eyeballs, I’ll spare you those and just reiterate: USE A SAFETY GLASS. The safety glasses I recommend are classified Z87.1. This rating ensures that your eyes get some UV protection from other welders around you and from flying sparks when you’re grinding.
You also want to protect your ears while welding and grinding by using earmuffs or earplugs. When the fast spinning wheels come into contact with steel it is much stronger and prolonged exposure can cause pain or even temporary deafness.
It is important to weld in a well-ventilated area. MIG welding produces fumes that you should not breathe. If you are welding and working for more than 30 minutes, wear a mask or respirator that protects you from metal fumes.
DO NOT WELD GALVANIZED STEEL. Galvanized steel contains a zinc coating that is applied to industrial steel to prevent rust for a long time. (Think lampposts and bridge abutments) This zinc coating produces a carcinogenic and toxic gas when burned. Exposure to burn skin can lead to heavy metal poisoning, also known as “welding chills.” These are flu-like symptoms that can last for a few days but can also cause permanent damage. This is not a joke. I have witnessed someone ignorantly welding galvanized steel and immediately felt the effects and had to be rushed to the hospital, so don’t do it!
How To Weld
Molten metal slag can splash several meters from the weld. Grinding sparks can fly even further. Any bags of sawdust, paper or plastic in the area can ignite and catch fire, so keep a tidy welding area. More often than not, your attention will be focused on the parts you’re welding, and not on the area around you, so it can be difficult to see what’s going on behind you if something catches fire. Reduce the chances of this happening by removing all flammable items from your welding area.
This is a good precaution for any shop, but keep a fire extinguisher at the exit door of your workshop. Co
Fire extinguishers are the best type of fire extinguishers for welding. Water extinguishers are not a good idea in a welding shop where you are next to a machine that basically converts the energy from the wall into lightning.
The main types of welding used in industry and by home engineers are commonly known as MIG welding, TIG welding, arc welding, gas welding. Without a doubt, MIG welding is the most common form of welding practiced, but there are other options for melting metals.
Learning To Weld
GMAW welding or Gas Metal Arc Welding (often called MIG welding) is the most widely used type of welding and perhaps the easiest to master in industry and home use. The GMAW process is suitable for melting mild steel, stainless steel and aluminium. A few years ago the full name – metal inert gas (MIG) welding was changed to gas metal arc welding (GMAW), but if you call it that most people don’t know what the hell you are talking about, called MIG welding. it definitely sticks.
MIG (Metal Inert Gas welding) is a semi-automatic arc welding process in which a wire electrode and consumable shielding gas are passed through a welding gun, also known as a torch. The machine produces a massive electric current that travels through the wire to the workpieces and melts and melts both the wire and the base metal together.
