Welding is a process that joins two pieces of metal by heating them until they join. Welding is used in a variety of applications, including construction, manufacturing, and engineering.
The welding process begins with the application of heat to the metal. This heat melts the metal and causes it to flow together. The weld is then formed when the molten metal cools and solidifies. Welders use a variety of welding equipment to perform the welding process. The most common welding equipment includes a welder, an arc welder, and a mig welder. Welder types vary based on the type of welding being performed.
Welding Techniques
There are a number of welding techniques, but the most common is arc welding.
An arc welder uses an electric arc to create a weld. The electric arc melts the metal and forms a joint. Arc welding is used in a variety of applications, including construction, manufacturing, and engineering.
Gas tungsten arc welding (GTAW) is another common welding technique. GTAW uses a gas supply to create an arc between the tungsten electrode and the metal workpiece. MIG welding is a type of welding using a gas-shielded metal-joint welding process. MIG welding uses a small, powerful torch to create a weld.
Welding with Galvanized Steel
Welding galvanized steel or other steel can cause more problems than just health risks. If the zinc coating on galvanized steels becomes weak, it can cause the welds to become weak. A coating that is hard to penetrate is more difficult and can cause welds to have inclusions and porosity. It is also common that there is no fusion at the toes of welds.
When you are welding galvanized steel, the zinc coating quickly evaporates. That will produce an oxide of zinc that mixes with the air. It is possible that this gas will cause you to experience short-term harm to your health, or metal fume fever. Welders who inhale the fumes may have flu-like symptoms.
It is certain that using a standard arc welding machine is the best way to weld galvanized steel. Arc welding is an effective and versatile technique. It is done by alternating currents to produce a high-heat arc that melts your flux. If you can, work outside using an arc welding tool.
The best welding rod to work with galvanized steel is the E6011, because it has a cellulosic flux coating. We think that the cellulosic flux is ideal to use against the zinc coating because it produces an aggressive arc, has the lowest silicon content, and generates a lot of shielding gases.
