What is Weld Scale? - Definition from Corrosionpedia

Weld scale should not be confused with weld slag.Weld slag forms on top of a weld bead after the weld cools when using a welding process that uses a flux.Weld slag is inherent to processes such as shielded metal arc welding,flux cored arc welding and submerged arc welding.Weld scale,on the other hand,is not the result of solidified flux.What is Weld Scale? - Definition from CorrosionpediaWeld scale should not be confused with weld slag.Weld slag forms on top of a weld bead after the weld cools when using a welding process that uses a flux.Weld slag is inherent to processes such as shielded metal arc welding,flux cored arc welding and submerged arc welding.Weld scale,on the other hand,is not the result of solidified flux.Welding Procedures (overview) QA/QA ConstructionWelded Steel Tanks for Oil Storage.American Welding Society.American National Standards Institute B31.1 Power Piping B31.2 Industrial Gas Air Piping Slag Inclusion.Slag inclusions are non metallic solid material entrapped in weld metal or between weld and base metal.In a radiograph,dark,jagged asymmetrical shapes within the weld or
