What Is Submerged Arc Welding (SAW) and How Is It Different from Other Welding Processes?
Submerged Arc Welding (SAW) is a high-efficiency welding process that uses a continuously fed consumable electrode and a granular flux. The flux covers the weld area and prevents contamination from the surrounding atmosphere.
The American Welding Society (AWS) defines SAW as a process where an electric arc forms between the electrode and the workpiece, leading to the fusion of materials beneath a layer of flux. This definition highlights the unique aspects of this welding method.
SAW provides several advantages, such as deep penetration, minimal spatter, and a clean weld surface. These characteristics contribute to strong, high-quality welds. The process is predominantly used in industrial applications for thick materials, such as in shipbuilding and pipeline construction.
According to the National Institute of Standards and Technology (NIST), SAW is especially effective in joint configurations where deep penetration and high weld quality are critical.
SAW may face challenges such as the need for proper flux handling and potential fume generation. These issues can impact the overall efficiency and safety of the welding process.
The global SAW market was valued at approximately $3.08 billion in 2020 and is projected to grow steadily in the coming years, according to a report by Research and Markets. This trend reflects the increasing demand for automation in welding.
The impacts of SAW extend into various sectors, including manufacturing and construction. Its efficiency can lead to reduced production costs and time, which contributes positively to economic growth.
Health risks may arise due to exposure to welding fumes, while environmental considerations include the disposal of used flux. Economic benefits include lower labor costs and higher productivity rates.
Examples of industry impacts include improved structural integrity in transportation projects and reduced welding time in manufacturing plants.
To mitigate health and environmental risks, organizations like the Occupational Safety and Health Administration (OSHA) recommend proper ventilation systems and personal protective equipment for workers.
Effective strategies to minimize fume exposure include the use of local exhaust ventilation and adopting automated welding systems, which can reduce manual labor. These practices contribute to safer working conditions and enhanced worker productivity.

-
Power Supply:
The power supply in submerged arc welding (SAW) provides the electrical energy for the welding process. This equipment typically operates on direct current (DC) or alternating current (AC). DC is preferred for its stability and control over the arc and the heat produced. According to a study by the American Welding Society, the power supply must handle a considerable amount of current to facilitate deep weld penetration and high deposition rates. Choosing the right power supply is crucial, as it can influence the quality and characteristics of the weld. -
Welding Head:
The welding head directs the welding wire and flux to the weld joint. It is engineered to maintain a consistent arc length and to facilitate the efficient melting of the filler material and flux. There are manual and automatic welding heads. Automatic heads allow for higher production rates and consistent quality. Industry research indicates that automatic welding heads are increasingly common for large projects where uniform welds are necessary. -
Flux Delivery System:
The flux delivery system supplies the granular flux material used in submerged arc welding. Flux protects the weld pool from contaminants in the atmosphere, enhances penetration, and helps shape the bead. The system usually includes a hopper and feeds mechanism that ensure a continuous supply of flux. Proper flux management contributes to fewer defects in weld quality. The Welding Institute reports that improper flux application can lead to oxidation and porosity in welds. -
Welding Wire Feeder:
The welding wire feeder controls the feed rate of the welding wire into the weld pool. It is vital for maintaining a steady and adequate supply of filler material. Feeders can be equipped with synchronized motion for seamless welding operations. According to industry experts, an accurate wire feeder can significantly reduce spatter and improve overall efficiency in production. Users suggest opting for feeders that offer precise control mechanisms, especially for complex welding tasks.
How Does the Submerged Arc Welding Process Work Step-by-Step?
The submerged arc welding process works through a series of distinct steps. First, the welder prepares the workpieces by cleaning the surfaces to remove contaminants. Next, they align the pieces in the required positions for welding. Then, they select and set up the welding machine, which includes the power source and the feed mechanism for the filler wire.
Once everything is in place, the welder activates the machine to create an electric arc between the filler wire and the workpieces. This arc generates intense heat, melting both the wire and the workpieces. The molten metal forms a weld pool.
Simultaneously, the welder introduces a granular flux material over the weld area. This flux serves to protect the molten metal from atmospheric contamination and assists in stabilizing the arc. As welding progresses, the flux melts and rises to the surface, forming a protective layer over the weld pool.
After achieving satisfactory penetration and bead appearance, the welder completes the welding process by stopping the machine. The weld cools and solidifies as the flux naturally transforms into a glassy layer. Finally, the welder removes the flux slag from the surface to reveal a strong, clean weld seam.
By following these steps, submerged arc welding creates high-quality welds in various industrial applications.
