Subarc submerged arc welding machines prevent the contact of molten metal with oxygen during the welding process, allowing high-quality and clean weld seams to be obtained. In this method, the welding area is constantly covered with a layer of powder, 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 that may occur during welding. In this way, the resulting weld seam is more successful in terms of strength and aesthetics. Subarc submerged arc welding machines offer an effective solution especially in joining thick sheets and large structural elements. This technology, which is frequently preferred in sectors such as shipbuilding, pipelines and heavy-duty machinery, increases production efficiency thanks to its high melting speed and deep penetration feature. In addition, the automation options used during the process both reduce labor costs and help standardize the 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 special equipment that performs the welding process under a layer of powder and creates high-quality, clean and durable weld seams. This technology is frequently preferred, especially in the joining of thick materials and large-scale projects. During the submerged arc welding process, the arc area is covered with welding powder; thus, contact with oxygen and other atmospheric gases is minimized, the seam quality is increased and the process becomes more reliable.
In this process, the arc between the welding wire and the workpiece is formed in the submerged arc atmosphere. The heat generated by the arc melts the wire and the welding area, turning two or more parts into a single whole. The melted powder protects the welding seam by turning into slag and is then easily cleaned.
The prominent components in submerged arc welding machines are as follows:
Power Source: The unit at the heart of the process that provides high amperage current.
Wire Feed Unit: It provides a constant melting rate by delivering the welding wire to the welding area at a regular speed.
Powder Feed System: It directs the welding powder to the arc area and creates a protective effect during the process.
Welding Cart (Optional): It is a mechanical auxiliary system that provides movement along the welding line in projects suitable for automation.
Submerged arc welding machines are used in a wide range, especially from the shipbuilding sector 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, the submerged arc welding method both saves time and offers superior mechanical properties.
- Wide Current Range and Adjustment: Allows for quick determination of ideal welding parameters for materials of different thicknesses.
- Automation Integration: Increases work efficiency by easily adapting to robotic arms or automatic welding carts, minimizing human error.
- Deep Penetration Ability: Maintains high quality standards while providing strong and durable joints in thick sheets in a single pass.
- Reusable Welding Powder: Reduces consumable costs since welding powder can be largely recycled.
