Application and Benefits of Shielded Metal Arc Welding Process

Shielded metal arc welding process, also known as "stick welding." This is because the welding seam is formed by using a flux-coated welding rod, which is a metal rod fixed in a metal rod clamp connected to the power source. The current passes through the electrode and contacts the base metal. At the same time, the flux produces gas to protect the arc between the electrode and the welded metal. This can prevent atmospheric gas pollution, and make the shielded metal arc welding process different from GMAW, which is suitable for outdoor work.

Understanding the shielded metal arc welding process

Like other arc welding processes, the shielded metal arc welding process is tightly performed. It also uses AC or DC power to transfer current to the electrode fixture to generate an arc, which leads to the high-temperature melt of the electrode tip and the connecting part of the workpiece. The welder maintains the arc length by maintaining a consistent space between the melting pools formed on the electrode and workpiece. Once the arc is removed from the workpiece, the joint is obtained.

What is the use of shielded metal arc welding process?

The shielded metal arc welding process can be used for various types of metals and various thicknesses. It is usually used for heavy-duty operations involving industrial steel such as carbon steel and cast iron, as well as operations involving low alloy steels, high alloy steels, and nickel alloys. The shielded metal arc welding process is used in various industries, including construction, assembly lines, shipbuilding, subaquatic welding, and agricultural machinery manufacturing.

The equipment of the shielded metal arc welding process is easy to carry and can be used in various environments, from indoor to outdoor to on-board ships at sea. Although the shielded metal arc welding process is one of the oldest forms of welding, new technologies are always advancing the process and making it more efficient. When experienced shielded metal arc welding process welders know how to choose the right electrode, welding speed, and arc length (and use clean materials), shielded metal arc welding process welding can provide reliable welding for various industries.

Advantages of shielded metal arc welding process

There are many advantages to shielded metal arc welding process, including:

• Lower equipment costs: Compared with other welding methods, the shielded metal arc welding process equipment is simple and inexpensive.

• Lightweight and portable: Shielded metal arc welding process equipment is easy to transport and is a convenient method of use.

• Built-in shielding: Because the flux-covered electrode produces its own protective gas, no additional external protective gas is required, so the shielded metal arc welding process can be performed outdoors.

• Multi-function: The shielded metal arc welding process can be used for various alloys and metals, as well as for multiple positions.
