welding slag forming agent

Calcium, Potassium, Sodium, or Silicon are welding slag forming agents. Adding in the flux can effectively protect the molten pool from air pollution. The welding slag can make the welding props better appearance and can quickly support the full position after welding. Molten pool. Welding slag coverage can also ease the cooling rate of the filler metal. This feature is especially important for the welding of low alloy steels.
