How Does TIG Welding Work

Have you ever thing what does TIG stand for in welding? Welding processes involving heat require inert tungsten gas (TIG). An electric arc produces heat. The electrodes used in this process are non-consumable. TIG is also a welding technique, which connects metals.  Today you will learn How Does TIG Welding works.

It applies a non-consumable electrode to two metals and uses inert gas ACDCo to join the metals, sometimes even without fillers. In most cases, weld rods do not contain filler material. It involves inserting them directly into the welding zone and melting and fusing them with the base. Aluminum alloys and magnesium are mainly welded with TIG. The TIG welding process is quite tricky but you can perform it effortlessly if you follow the exact instructions discussed below.

How Does TIG Welding Work

The positive terminal connects the workpiece, and the negative terminal connects the electrode. The tungsten and workpiece generate a high-intensity arc. You have to read the complete article attentively to learn how welding works. It provides a sound opportunity for beginners to establish their careers. For the metal plates to be joined, arc heat is put to work. Various shielding gases, including argon and helium, are provided to prevent rusting and oxidation.

How TIG Welding Works?

It is important to understand the following things before you begin TIG welding. You will also learn how to use a TIG welder. There are a variety of TIG welders available on the market including Inexpensive TIG welder, Portable, and Hobby TIG Welder. You can purchase anyone according to your needs. Here is not the end, TIG welding machines also come in various price ranges includes 500, 800, 1000, 1500, and 2000 that perform the best. These are the TIG welding basics that every beginner must learn first.

Power Source

Having a high current power source is essential for TIG welding. A TIG welder often uses AC or DC power to power the machine. Aluminum alloys and magnesium require AC power, whereas stainless steels, mild steels, coppers, and nickel alloys require DC (direct current). Transformers, rectifiers, and electronic controllers make up the power source.

TIG Torch

TIG welding relies heavily on the TIG torch. Water or air-cooled tungsten electrodes are used along with a nozzle. Collets hold electrodes tightly in place. During welding, the gas shield nozzle helps prevent oxidation. As a result of a high level of heat, nozzles need to be replaced frequently.

Shielding Gas

Argon or helium are commonly used to shield welding zones. These gases protect metals from oxidation. Welding zone gases enter it due to its regulation.

Filler Material

Welding of thick material requires filler, which is not necessary for thin sheets.

TIG Welding Process

The tungsten electrode is supplied with low voltage and high current via power. During the process, an electrode is connected to one terminal and a workpiece to the other. When a current flows through a non-consumable tungsten electrode and the workpiece, it creates an electric arc. This electric arc melts the base metal and welds it together.

The shielded gas covering the weld prevents oxygen from entering thus, preventing chemical reactions with oxygen. The shielding gas also regulates valve flow. Shielded gas also produces plasma, which enhances the welding process for perfect results. Occasionally, some filler is injected manually into welds when thick joints require filler material.

Things to Keep in Mind while Welding

  • Protect yourself at all times.
  • Physicists require knowledge of the machines they work on.
  • Ventilate your workspace.
  • The right current type should be used.
  • Beginners should seek professional assistance.

Let’s look at the above points briefly.

The job of welding can be extremely challenging. Moreover, It takes time and patience to achieve results. Above all, welding is a dangerous job. Therefore, safety must be a top priority during the performance of such a job. So the question arises that is you really want to know How does TIG Welding works?

Working with welding equipment can expose you to hazardous fumes and gases. Before you begin the project, you should consider a few things. A welding machine is necessary for the job. Helmets, glasses, gloves, welding jackets, and welding gloves are among the welding gear.

You must also possess sufficient knowledge about welding work and the welding machine, in addition to wearing the proper gear. Hence, understanding all the instructions can prevent any mishaps that you misuse the appliance. If you are a beginner and don’t know what is TIG welding, Proconsumption also provides complete information on it.

While welding, it is also a good idea to ventilate the area. You are exposed to fumes and gaseous particles when welding; therefore, it is extremely important to ventilate the area properly.  Consequently, the fumes and toxic gases in the air will quickly evaporate. Do you know how does a tig welder work?

In addition to AC and DC currents, there are also alternating currents. The welding of various types of materials requires both types of current, AC and DC. If you are welding aluminum, use a DC current instead of an AC current.

Never attempt to learn welding yourself as a last precaution. You should not practice welding independently if you do not know how to weld. Sparks, fumes, and gases can cause severe burns when welding. That is why you should join a welding school and learn from the best instructors.

Advantages of TIG Welding

TIG welding has several advantages, as described below

  • It is possible to TIG weld steel and aluminum.
  • You can achieve perfect precision when you learn the TIG welding technique correctly.
  • A TRIG welder can also weld in congested corners and even up and down. TIG welding offers advantages over other welding processes, such as the flexibility it provides for dealing with multiple situations.

Frequently Asked Questions

How do TIG welders work?

In a welding arc, an electric torch sends current through a tungsten electrode. The filler rod is consumed along with the weld puddle (molten metal) to make a final product.

What is TIG welding, and how does it work?

TIG welding, sometimes known as Gas Tungsten Arc Welding (GTAW), utilizes the electric arc to produce a weld with tungsten electrodes that will not melt or burn off. Unlike MIG welding, TIG welding consists of melting the metal together without using a filler metal.

Can you TIG weld without gas?

Gas is necessary for Tig welding, no more, no less! Welding tungsten electrodes and pools from oxygen require gas. Gas is also used to cool most Tig Welder torches, so not using gas could mean they burned out.

Final Thoughts

There are a few factors to consider when deciding whether to use TIG welding. Consider your expertise if you are one. Although TIG welding can deliver the best results in some cases, this method only works if the welder can correctly utilize the machine. To become proficient at welding, you should either start with MIG and progress from there or practice with TIG first. In the end, If you read the complete article, you surely learn something worthy about How does TIG Welding Work.

Additionally, welding may involve some dangerous machinery regardless. The quality of the welding projects will necessarily be your priority, but you should also prioritize everyone’s safety. Therefore, we recommend getting help from someone with more experience before trying TIG welding. Nevertheless, you will be able to do some amazing things with these machines if you put in the effort to learn the craft.
