What is Tungsten Inert Gas Welding Used For?
Tungsten Inert Gas (TIG) welding is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas, typically argon or helium. A filler material may be used, but TIG welding can also be done without it.
At its most basic level, TIG welding involves creating an electric arc between a pointed tungsten electrode and the metal being welded to generate heat that melts both materials and produces a strong joint. A hand-held torch holds the tungsten electrode in place at a set distance from the metal being welded. When current passes through the circuit and arcs across this gap, the metal melts and produces a weld.Additionally, the low heat input limits the amount of distortion caused by welding, making it ideal for producing high-precision joints. As a result, TIG welding is often used in applications where strength and accuracy are key factors such as aerospace or medical device manufacturing.
To ensure quality welds, proper technique must be employed when using TIG welding equipment. This includes maintaining a consistent arc length between the tungsten electrode and the metal being welded, controlling filler material addition rate by hand, and monitoring the shielding gas flow rate at all times. With the right technique and high-quality equipment, operators can produce strong and reliable welds with TIG welding.,
What TIG Welding is Used For?
TIG welding is widely used in many industries, including automotive and shipbuilding. The process is used to weld aluminum, stainless steel, brass, titanium, copper alloys and a variety of other metals. It’s also commonly employed for making pipe joints, fabricating sheet metal structures and creating structural components for aircraft.
In addition to being used for fabrication purposes, TIG welding can be utilized in repair operations as well. Since the process operates at a much lower temperature than other welding processes (around 6500°F) it does not cause warping or distortion on the surrounding material. This makes it ideal for repairing thin materials that would otherwise be difficult to work with due to warping caused by higher heat input processes like oxy-fuel welding.
Finally, TIG welding can be used to co-weld multiple materials together such as aluminum and steel. This is especially useful for applications where two or more metals need to be joined that would otherwise require multiple welding processes. By combining the materials into one weld puddle, operators can save time and increase efficiency in the fabrication process.,
Types of Tungsten Electrodes
Now that we have a better understanding of the TIG welding process, let’s take a closer look at tungsten electrodes.
Ceriated tungsten electrodes, also known as thoriated tungsten electrodes, are one of the most popular types of electrodes. These electrodes contain a small amount of cerium oxide in their composition, which increases the electrical conductivity and enables better arc starts on low-amperage settings. Ceriated tungsten is ideal for welding aluminum and mild steel and can be used with AC power sources.
Lanthanated tungsten electrodes are a type of welding electrode composed of tungsten and alloyed with 1.5-2.4% lanthanum oxide (La2O3). The addition of lanthanum oxide to a tungsten electrode increases its arc stability, allowing the welder to achieve higher levels of current density and lower heat input when welding aluminum. These unique properties make lanthanated electrodes ideal for applications where high levels of precision and accuracy is needed, such as in aluminum manufacturing processes.
Thoriated (thorium-tungsten) electrodes are one of the most common types of tungsten used in welding. This particular type of electrode is made by adding a small amount of thorium to pure tungsten, and it’s known for being more durable than other types.
The main benefit of thoriated electrodes is that they provide superior arc stability when compared to pure tungsten electrodes. The addition of thorium helps to reduce arc wander and creates a cleaner, more consistent weld. It also allows the user to set current levels lower than with regular tungsten, which means less heat build-up and less risk of burning through the workpiece.
Pure tungsten electrode is the most basic type of tungsten electrode and is made from pure tungsten metal. It’s typically used for relatively low-amperage welding jobs that require a strong, reliable arc and minimal heat input.
Pure tungsten electrodes are often used in aluminum welding because they provide good arc stability with low current settings. The drawback to this type of electrode is that it has a shorter lifespan than other types, making it less suitable for high-heat applications where wear resistance is needed. ,,
TIG Welder Buyers Guide
To help you with making a choice, we have put together a comprehensive TIG Welder Buyers Guide. In this guide, we will provide you with important points to consider before making a purchase, along with our roundup of the best tungsten for aluminum available on the market today.
When selecting a TIG welder for aluminum, it’s essential to know that all brands and models are not created equal. To make sure you get the right product for your welding needs, take into account these factors:
The TIG welding process uses either alternating current (AC) or direct current (DC). AC can change the flow of current with time which doesn’t happen in DC. This can provide more flexibility for welding but does require a more powerful machine.
AC welding is ideal for thinner aluminum materials, such as sheet and tubing. DC welding works better on heavier sections of aluminum. To weld aluminum effectively with a TIG welder, you will need an AC/DC inverter, which can switch between the two currents.
Tungsten rods have varying degrees of heat resistance depending on the elements they are composed of. When utilizing an Alternating Current, this is not a concern; however, when using Direct Current, certain tungsten rods can be destroyed by excessive heat.
AC welding also requires larger–diameter tungsten electrodes. This means that you must use a specific type of tungsten rod for AC welding. For DC welding, most types of tungsten will work just fine.
Type of metal/alloy
The type of metal you choose for a tungsten material is important, as it can significantly impact the performance and quality of your welding project. When selecting a tungsten for aluminum, it’s important to understand that different types of metals contain varying levels of impurities and alloys which can affect overall weld puddle control, arc starting ability, and current carrying capacity.
For aluminum applications, pure tungsten is the most common choice. Pure tungsten has a low contamination level and provides excellent arc stability at higher amperage settings than other types of metals.
Zirconiated tungsten is also a solid choice for aluminum welding, and it offers several benefits over pure tungsten. Zirconiated tungsten has a slightly higher contamination threshold than pure tungsten, which means it can tolerate a bit more impurity before the weld starts to become unreliable.
It’s important to consider the metal composition and impurities in a tungsten material before selecting it for use in aluminum welding projects. The type of tungsten chosen should provide the best balance of arc performance, weld puddle control and current carrying capacity for your application. Additionally, it should reduce contamination risk as much as possible.
The size of the electrode you choose for your TIG welder is important for two reasons: it determines how much current is needed to effectively conduct heat, and it affects the weld pool shape. Generally speaking, larger electrodes will require more current but will also create a wider weld pool, which can be beneficial when welding aluminum.
When selecting an electrode size for aluminum, keep in mind that small diameters are typically used with thin metals and large diameters are best suited for thicker materials.
Price is another important factor to consider when shopping for tungsten for aluminum. Tungsten electrodes can range in price from a few dollars each up to several hundred dollars per electrode.
Generally speaking, higher-priced electrodes will offer improved performance and better arc stability. However, there are some lower-cost alternatives that can deliver good results as well. It’s best to shop around and compare prices before making a purchase to make sure you get the best value for your money.
The cost of tungsten electrodes should be factored into the overall budget for any welding project. If cost is an issue, then selecting lower-priced options may be the way to go; however, it’s important to make sure that the quality of the tungsten is not compromised.
It’s also worth noting that purchasing electrodes in bulk can often result in significant discounts compared to buying individual units. This is something to consider if you plan on doing a lot of aluminum welding projects in the future. ,,,
