The main characteristics of submerged arc welding are as follows:

The main characteristics of submerged arc welding can be summarized as high efficiency, high quality, material saving, and environmental friendliness, but it also has some limitations:

I. Core Advantages
High efficiency: High current and strong penetration, suitable for welding thick plates, with efficiency 5-10 times that of manual arc welding.
High quality: Flux protection reduces porosity, resulting in dense welds and stable mechanical properties.
Material and energy saving: No spatter, high utilization rate of welding wire, small groove, and less filler metal required.
Environmentally friendly: No arc light, less smoke and dust, and improved working conditions.
II. Limitations
Position limitations: Mainly suitable for flat welding or long straight/circular welds with small angles of inclination.
Material limitations: Difficult to weld highly oxidizable metals such as aluminum and titanium.
Complex equipment: Requires a larger initial investment.
Not suitable for thin plates: The arc is unstable when the current is less than 100A, making it unsuitable for welding thin plates less than 1mm thick.
III. Typical Applications

Mainly used for welding thick and large structures such as pressure vessels, pipelines, ships, and bridges.
