Tig Welding for Dummies: A Beginner’s Guide to Tig Welding Basics
Tig welding, or Tungsten Inert Gas welding, is a popular method of welding that uses a tungsten electrode combined with an inert gas to join two pieces of metal. This method of welding is commonly used for applications that require precise welds, such as aluminum, stainless steel and other metals. It’s also used to weld pipes, thin metals and other materials. In this article, we’ll provide a beginner’s guide to tig welding basics – from the equipment you’ll need to the techniques you’ll use.
What is Tig Welding?
Tig welding is a type of arc welding that uses a non-consumable tungsten electrode to produce the weld. The tungsten electrode is usually made of tungsten, a rare metal that is strong, heat-resistant and non-consumable. The weld is then protected from the atmosphere with a shielding gas, such as argon, helium or a mixture of both.
Tig Welding Equipment
To get started with tig welding, you’ll need some specific equipment. You’ll need a welding machine, a welding torch, a tungsten electrode, a foot pedal, a filler rod and a shielding gas.
The welding machine is the heart of the system and provides the necessary current to the welding torch. It’s important to choose the right type of welding machine for the job – for example, an AC/DC machine is best for welding aluminum, while a DC machine is best for welding steel.
The welding torch is connected to the welding machine and provides the arc that heats the metal and creates the weld. It also provides the shielding gas and controls the flow of the filler rod.
The tungsten electrode is the non-consumable part of the welding torch. It’s the tip of the welding torch that provides the arc and is usually made of tungsten or a tungsten alloy.
The foot pedal is used to control the current and arc length of the welding torch. It’s important to get the right type of foot pedal for the job.
The filler rod is the consumable part of the welding torch and is used to fill any gaps or holes in the weld. It’s important to choose the right type of filler rod for the job.
Finally, the shielding gas is used to protect the weld from the atmosphere and is usually a mixture of argon and helium.
Tig Welding Techniques
Once you have the necessary equipment, you’ll need to learn the different tig welding techniques. The most common technique is known as the “push” technique, which involves pushing the welding torch forward as you weld. This technique is used for welding thicker materials and is best for welding in a straight line.
The “pull” technique is another common tig welding technique and involves pulling the welding torch back as you weld. This technique is used for welding thinner materials and is best for welding curved lines.
Finally, the “drag” technique is a combination of the push and pull techniques and is used for welding thicker materials.
Tig Welding Safety
It’s important to take safety precautions when tig welding. It’s important to wear the right safety gear, such as a welding helmet, gloves and protective clothing. You should also be aware of the dangers of welding fumes and take steps to reduce your exposure.
Tig Welding for Dummies: Final Thoughts
Tig welding is a popular method of welding that uses a tungsten electrode, an inert gas and precise techniques to join two pieces of metal. This method of welding is commonly used for applications that require precise welds, such as aluminum, stainless steel and other metals. It’s important to have the right equipment and to follow safety precautions when tig welding. We hope this beginner’s guide to tig welding basics has provided you with the information you need to get started with tig welding.
