Welding is a fabrication process where two or more parts are fused using specific tools. A welder uses a torch to produce the flame that welds the surfaces. The temperature and the intensity of the flame are determined by the type of gas used. There are various types of gases used in welding fabrication, including argon, helium, and nitrogen. Each gas has its own benefits and drawbacks, so it's important to choose the right one for your project.
3 Types of Gases Used in Welding Fabrication
Argon is a common welding gas because it is inexpensive and easy to find. It is also non-reactive, which means using argon won't cause metal corrosion. However, argon can be difficult to control, so it is not always the best choice for beginners.
Helium is another popular welding gas because it is very light. This makes it easier to control than heavier gases like argon. Helium is also non-reactive and doesn't corrode metal. However, it can be more expensive than argon.
Nitrogen is another welding gas that's often used for its benefits. It is a non-reactive gas and doesn't corrode metal. Nitrogen is also less likely to cause welding defects than other gases. However, it can be more expensive than argon and helium.
When choosing a welding gas, it's important to consider your project needs. If you are welding something sensitive, you may want to choose a gas like nitrogen that's less likely to cause defects. If you are welding something big and heavy, you may want to choose a gas like helium that's easier to control.
