Why Is Co2 Used In Welding

Shielding gases are used to assist in welding, and they have a crucial impact on arc stability, weld penetration profiles and the transfer process you use. It is important to select the right one, and carbon dioxide is one of the most popular choices. It is the only substance which can be used in its untainted form without adding an inert gas, such as helium or argon. In addition to being more economical than other gases, it is also contributing to the good mechanical properties of metals. Commonly used for welding of carbon steels and limited to short circuit process, carbon dioxide can help achieve some useful assets such as durability and crack-resistance. Here are some of the crucial reasons why CO2 is used in metal fabrication.


CO2 Protects the Metal


Using CO2 is very common in Perth steel fabrication. Its primary purpose is to prevent the exposure to harmful elements such as oxygen, hydrogen and nitrogen, which exist in the air atmosphere. When these elements react with the weld pool, the undesirable results include high porosity and excessive spatter. Carbon dioxide acts as a shield from different types of impurities such as dust, air and other gases. It provides fantastic protection for metals during and after the welding process.


It is Inexpensive


Engineering services such as metal fabrication can be costly. Working with other shielding gases can be expensive, CO2 is the most affordable solution. Since arc generation rate is high, carbon dioxide is lowering the price of welding and offers an excellent value for money. It is a fantastic choice if you want to cut the costs of the material.


It is Works Well for Welding Thick Materials


Bonding heavy and dense metal parts together can be challenging. CO2 is very useful for welding thick materials because it enables better joint penetration. When it is mixed with other gasses, it provides even greater arc stability than pure carbon dioxide.


It Improves Weld Quality


When looking for engineering Services Perth-wide, your first priority should be high weld quality. CO2 significantly improves quality since the level of hydrogen in the weld metal is low, which contributes to crack-resistance and other great mechanical properties. Carbon dioxide also enhances the appearance of metal while reducing post-weld clean-up.


CO2 Speeds Up the Welding Process


Using CO2 speeds up the welding process and allows higher productivity rates. This is crucial for fast manufacturing of metal components. MIG welding with pure carbon dioxide improves welding performance and allows higher speeds.


Working With CO2 is Less Messy


CO2 has been known as a gas that increases spatter during the welding process. However, using innovative arc welding technologies can significantly reduce spatter when you are working with pure carbon dioxide. These advanced equipment’s can weld even very thin sheets of carbon steel. Additionally, the formation of slag during welding is minimal due to the high deposition efficiency, and you don’t need to remove it after each pass.
