Advantages and Disadvantages of Submerged Arc Welding

Advantages and disadvantages of submerged arc welding should be carefully considered when evaluating welding techniques used in industry. One of the most important advantages of this method is achieving high-quality and smooth weld seams. Additionally, thanks to the protective flux, the weld pool is not affected by external factors.

Advantages and disadvantages of submerged arc welding are also significant in terms of occupational safety and production efficiency. No spark spatter occurs during welding, and it is easier to protect the operator. However, the method’s applicability is limited to certain positions, which is a disadvantage. Furthermore, the equipment investment may be high and yields effective results only on thick materials. Therefore, it is necessary to analyze in advance whether the method is suitable for the intended application.

Points to consider before choosing submerged arc welding:

Yields effective results only on thick and flat surfaces.

Can only operate in the horizontal position; not suitable for vertical or overhead welding.

Requires high initial investment, but provides efficiency in the long term.

Enhances operator safety with low smoke and spark levels.

The selected combination of welding wire and flux must be fully compatible with the material.

Saves time and labor costs in mass production facilities.

What is Submerged Arc Welding?

Submerged arc welding is an industrial welding technique commonly used to join metal parts. This method stands out with its strong bonding capability, particularly for thick and heavy metals.

During the welding process, the weld seam is covered with a special layer of flux. This flux protects the weld pool by isolating it from the external environment and ensures a high-quality result. When considering the advantages and disadvantages of submerged arc welding, it becomes clear that this method is especially suited for heavy industry applications.

As a type of arc welding, the electric arc forms between the electrode and the workpiece, initiating the welding process. During this process, the flux layer serves both as a protective and alloying agent. This system, which delivers high heat and deep penetration, is frequently preferred in large steel constructions, shipbuilding, and pipe manufacturing.

The submerged arc welding method requires less operator intervention compared to manual methods and significantly shortens the production time. This helps businesses save both time and cost. Moreover, since it generates no smoke, light, or spatter, operator safety is improved. The advantages and disadvantages of submerged arc welding should be evaluated based on the material type and welding position to determine its suitability.

Prominent features of this method include:

Can be easily integrated into automated welding systems.

Creates strong and homogeneous weld seams.

Increases efficiency when used with a welding machine.

Allows the selection of welding wire in various diameters and alloys.

Frequently Asked Questions

Submerged arc welding is typically applied to carbon steels, low-alloy steels, and certain types of stainless steel. It provides high penetration and durability, especially for thick and flat surfaces.

This welding method achieves homogeneous, durable, and clean weld seams. Since there is no light, smoke, or spatter, operator safety is enhanced and the work environment becomes more comfortable.

Its use is limited to horizontal positions, it is not effective for complex geometries, and it has a high equipment cost. It is also not recommended for thin materials.

Submerged arc welding allows welding without being affected by external factors by covering the arc area with flux. Compared to methods like MIG or TIG, it requires less operator skill and is more suitable for mass production.

This method is widely used in heavy industry, especially in shipbuilding, pipeline manufacturing, steel construction, and the energy sector. It is preferred in projects that demand high strength and efficiency.
