Differences between gas and no gas welders
Gas and no gas welders are two different types of welding machines that are used for joining metal pieces together. While they both serve the purpose of welding, there are some key differences between the two.
1. Gas Welders
Gas welders, also known as gas shielded welders, use a welding process called Gas Metal Arc Welding (GMAW) or Metal Inert Gas (MIG) welding. These machines use a combination of a shielding gas and a consumable wire electrode to create an electric arc for melting and joining metals.
The shielding gas, usually a mixture of argon, carbon dioxide, and other gases, is used to protect the molten metal from oxidation and to stabilize the welding process. This makes gas welders suitable for welding a variety of metals, including steel, aluminum, and stainless steel.
Gas welders offer several advantages, including higher welding speed, better control over the welding process, and the ability to perform welds in various positions. However, they require a constant supply of shielding gas and the setup can be more complex compared to no gas welders.
2. No Gas Welders
No gas welders, also known as flux-cored welders, use a welding process called Flux-Cored Arc Welding (FCAW). These machines use a flux-cored wire electrode that contains a flux compound. When the electrode is melted, the flux compound creates a shielding gas that protects the weld from oxidation.
No gas welders are commonly used for outdoor welding or in environments where a constant supply of shielding gas is not available. They are often portable and easier to set up compared to gas welders. However, they may produce more fumes and require more cleaning after welding due to the flux compound.
- No gas welders are generally more affordable compared to gas welders.
- They are suitable for welding thicker materials, such as structural steel.
- No gas welders can be used for different metals, but they are mostly used for mild steel and low-alloy steel.
Overall, whether to choose a gas or no gas welder depends on the specific welding needs and circumstances. Gas welders are generally preferred for high-quality and precise welding, while no gas welders are more suitable for outdoor or portable welding applications.
