Submerged Arc Welding Machines

Submerged arc welding machines prevent the molten metal from coming into contact with oxygen during the welding process, resulting in high quality and clean weld seams. In this method, the welding zone is continuously covered with a layer of dust, minimizing the air effect and thus making the welding process more stable. In addition, the consumables and protective powders used in these systems minimize slag and gas residues during welding. In this way, the resulting weld seam is more successful in terms of strength and aesthetics.

Submerged arc welding machines offer an effective solution especially for joining thick sheets and large structural elements. Frequently preferred in industries such as shipbuilding, pipelines and heavy-duty machinery, this technology increases production efficiency thanks to its high melting speed and deep penetration. In addition, the automation options used during the process both reduce labor costs and help standardize welding quality. These advantages make submerged arc welding machines a prominent choice in industrial production processes.

What are Submerged Arc Welding Machines?

Submerged arc welding machines are specialized equipment that perform the welding process under a layer of dust, creating high quality, clean and durable weld seams. This technology is especially preferred for joining thick materials and large-scale projects. During the submerged arc welding process, the arc zone is covered with welding dust, which minimizes contact with oxygen and other atmospheric gases, improves seam quality and makes the process more reliable.

In this process, the arc between the welding wire and the workpiece is formed in a submerged arc atmosphere. The heat generated by the arc melts the wire and the weld zone, fusing two or more parts into a single whole. The melted dust turns into slag, protecting the weld seam, which is then easily cleaned.

The components that stand out in submerged arc welding machines are as follows:

Power Supply: The unit at the heart of the process, providing high amperage current.

Wire Feeding Unit: Delivers the welding wire to the weld zone at a steady speed, ensuring a constant melting rate.

Powder Feed System: Directs the welding powder to the arc zone and creates a protective effect during the process.

Welding Trolley (Optional): In projects suitable for automation, it is a mechanical auxiliary system that provides movement along the welding line.

Submerged arc welding machines are used in a wide range of applications from shipbuilding to power plants. The advantages of this technology come to the fore when thick steel plates and large-sized structures need to be joined quickly. In projects requiring high strength such as pipelines, pressure vessels, steel bridges and similar projects, the submerged arc welding method saves time and offers superior mechanical properties.
