Gas welding galvanized steel involves using a specific type of gas to heat and melt the metal, and then joining it together. The most common type of gas to use when welding galvanized steel is an oxygen-acetylene mixture, as this combination produces a flame that is hot enough to melt the metal without burning it. The addition of an inert gas such as carbon dioxide can also be used to help reduce the amount of oxygen in the flame and prevent oxidation of the metal. With the right equipment and technique, a welded joint can be achieved that is strong and durable.

Best gas for welding galvanized steel Buying guide
Welding galvanized steel presents a few unique challenges compared to welding uncoated steel. The most important factor when choosing a gas for welding galvanized steel is to be certain that it is proper for welding zinc. A good option is Argon +2% oxygen, which provides the best shielding gas for welding galvanized steel. This gas mixture provides an inert atmosphere that prevents oxidation during welding, which keeps the zinc in the steel from oxidizing and affecting the weld. Additionally, this gas mixture is especially good for short-circuit welding, which is the most common welding technique used for welding galvanized steel. Another option is a blend of Argon and Carbon Dioxide, which provides a slightly more fluid weld pool and is a good choice for welding thicker sections of galvanized steel. However, it should be noted that this gas mixture is more prone to oxidation, so it’s important to use a high-quality flux when welding with this gas. Finally, another option is Helium, which provides a slightly better penetration when welding galvanized steel, but it is more expensive and can be difficult to find in some areas.
