To make machines and metal devices, you generally need to use welding. Welding is the process of melting two metal pieces and connecting them together. There are many applications of welding, including railroad construction, building construction, and shipbuilding. While you can weld almost any type of metal, some metals are more popular for welding than others. So, what are the most common metals used in welding?
Due to its ability to resist corrosion, aluminum is a popular metal for many industrial applications. Manufacturers often use aluminum for airplane parts, window frames, and kitchen utensils. Keep in mind that there are many aluminum alloys, and some are easier to weld than others.
Engineers and architects use steel for its durability, flexibility, and high corrosion resistance. You’ll find stainless steel in many famous bridges and buildings, such as the Empire State Building. Due to its ductility, steel is usually an easy metal to weld. However, welding a steel alloy, such as carbon steel, can be much more difficult. With more carbon, steel becomes more durable but less flexible, making it more challenging to weld.
If you need a metal that conducts electricity, copper is an excellent option. It’s also resistant to corrosion, making it a popular choice for wiring and electrical machines. While pure copper isn’t hard to weld, copper alloys can be more challenging.
Many statues and ornamental pieces use iron and iron alloys for their ductility, strength, and lustrous appearance. You can also find iron alloys like silicon iron bronze in pipes, fences, and kitchen appliances. In fact, welding is one of the most common uses for silicon iron bronze. Iron has a low melting point, which makes it a useful metal for welders.
So what are the most common metals used in welding? The answer is aluminum, steel, copper, iron, and some metal alloys.
