Argon Welding
Argon welding and using argon gas,
is commonly used to join or repair metal parts. Argon gas is
an inert gas used during welding. Inert gases do not
react with oxygen or other reactive gases, which prevents
unwanted chemical reactions from occurring during welding.
Argon welding is a type of welding used to join metal parts
at high temperatures. This process delivers argon gas to the weld
zone through a welding gun and tube. Argon welding, also
known as arc welding or TIG (Tungsten Inert Gas)
welding, is preferred to achieve a high-quality and clean joint during
welding.
Argon welding is particularly effective when used on thin
and delicate metal parts. This method is widely preferred for welding
metals such as aluminum, titanium, and stainless steel. When delicate
structures and aesthetically important parts need to
be joined or repaired, argon welding is preferred because it can provide less
deformation and a cleaner joint.
When performing argon welding, there are some important
factors that welders should pay attention to. Keeping the weld area clean
and oxygen-free helps prevent unwanted welding reactions. In addition,
the correct setting of parameters, such as the correct current,
voltage, and welding speed, is also essential for a quality argon weld.
What is Argon?
Argon welding is a welding process used as a
welding method and utilizes argon gas. Argon gas is an inert
gas used during welding. Inert gases do not react chemically with
oxygen or other reactive gases. This prevents unwanted oxidation or
reactions of metals during welding.
Argon welding is also commonly known as TIG
(Tungsten Inert Gas). This welding method is used to join pieces of metal
at high temperatures. The welder delivers argon gas through a welding
gun or tube to the weld area, where an electric
arc joins the metal parts.
What Does Argon Welding Do?
TIG welding is not an economical welding method. However, advances in the power supply industry, mechanical and automatic applications make TIG welding suitable for large-scale production. TIG welding method has always been the first choice in the range of applications requiring high standards.
TIG Welding Areas and Advantages
In the welding process known as TIG (Tungsten Inert Gas)
or argon welding, argon gas is used with a tungsten electrode.
It is a versatile welding method that can be used for all materials and
applications. The main application area is stainless steel, aluminum and nickel
alloys. The concentrated and stable arc ensures high quality welded metal
without slag and burrs.
Why Use Argon Gas?
Argon is used for welding due to its low cost, shielding gas
capabilities, and stability.
In addition to not reacting with other elements, it doesn’t
burst into flames when exposed to the extreme temperatures involved in welding.
Its natural abundance in the Earth’s atmosphere also makes
it an affordable gas option for welders.
Pure Argon for TIG Welding
When looking for TIG welding gas, you will require a pure
argon gas, which produces a clean weld with no oxidisation. It can
significantly increase your welding execution for many reasons;
- It’s heavier than air quality and offers complete protection of your weld.
- Prevents any burning through of thinner materials.
- Offers a consistent, reliable and narrow arc for a more precise weld.
- It requires less power and voltage during TIG welding and is more affordable than other options.
The only disadvantage to using pure argon versus other inert
gasses is that it cannot operate at high voltage, which may mean longer welding
times. However, with the excellent quality of argon, it may be worth taking the
extra time for a more accurate weld.
Frequently asked questions with Argon Gas
Is Argon Flammable?
Argon is non-flammable and does not support combustion. With the welding process sometimes reaching 7000 degrees Fahrenheit (ca. 3,871 °C), it is a safe option for welders.
In which welding processes is argon gas used?
Argon gas is frequently used, especially in the method known as TIG (Tungsten Inert Gas) welding or argon arc welding.
How to Store and Use Argon Gas?
Argon gas can be stored as a liquid or gas in pressurized cylinders. During storage, the cylinders must be sealed and stored securely. When used, it is released in a controlled manner with appropriate equipment, usually connected to welding machines. During the welding process, the correct flow rate and pressure of the gas must be ensured.
