Using a Weld Camera in Submerged Arc Welding
Submerged Arc Welding processes employ a granular flux that is dispensed onto the weld area to protect the molten weld and arc zone from atmospheric contamination. A thick layer of flux is typically put down during the welding process to completely cover the molten metal, preventing weld spatter and sparks from developing during welding.
