In which position can submerged arc welding only be performed?

Submerged arc welding is designed for efficiency and is most effectively performed in the flat position. This orientation allows for better control of the welding process and optimal use of the welding materials, resulting in high-quality welds. In the flat position, gravity assists in keeping the molten weld pool contained, reducing the likelihood of defects such as slag inclusions, and allowing for better penetration and heat distribution.

While submerged arc welding can be technically performed in other positions, the process is primarily advantageous and commonly used in the flat position due to the ease of manipulation and the overall quality of the weld produced. The other positions, such as horizontal, vertical, or overhead, may pose challenges that can lead to increased likelihood of defects and require specialized equipment or techniques to maintain the same level of quality encountered in the flat position. This makes flat position welding the preferred and only practical position for submerged arc welding in typical applications.
