Weld descaling is the removal of heavy, tightly adherent oxide films resulting from hot-forming, heat-treatment, welding, and other high-temperature operations. Weld descaling is performed prior to passivation.
Pickling removes metallic contamination and welding and heat-treating scales. Etching promotes surface adhesion.
Alkaline degreasing is a cleaning process that employs the use of more environmentally friendly solvents than vapor degreasing to remove contaminants, and is particularly effective against oils, waxes, and greases.
The baking process is used to prevent hydrogen embrittlement. This is a monitored process and is customer specified.
Media blasting is a process that provides a matte surface finish without any substrate material removal or chemical contamination.
