Shielded Metal Arc Welding: Understanding Slag Formation in the Welding Process
Shielded metal arc welding forms slag as a byproduct when flux, a solid shielding material, melts on the weld zone. In the molten weld pool, thermodynamic processes push unwanted elements, including the flux, to the surface. These elements cool and solidify, creating a layer of slag that protects the weld. Slag formation occurs due to … Read more
