Which type of SAW flux can be gathered and reused?

Fused flux in submerged arc welding (SAW) is a type that can be gathered and reused effectively. This is primarily due to its unique composition and structure, which allows it to maintain its performance characteristics even after being used in the welding process. When fused flux is subjected to heat during welding, it becomes molten and covers the weld pool, helping to protect the weld metal from oxidation and contamination.

After the welding operation, the solidified flux can be collected, cleaned of any impurities, and recycled for further welding applications. This reuse not only reduces material waste but also promotes cost efficiency in the welding process.

In contrast, bonded flux, granular flux, and liquid flux are either specifically formulated for single-use or cannot maintain their properties after being used in a welding operation, making them less suitable for reuse.
