Class Information
Number: 148/525
Name: Metal treatment > Process of modifying or maintaining internal physical structure (i.e., microstructure) or chemical properties of metal, process of reactive coating of metal and process of chemical-heat removing (e.g., flame-cutting, etc.) or burning of metal > Producing or treating layered, bonded, welded, or mechanically engaged article or stock as a final product > Utilizing wave energy (e.g., laser, electromagnetic wave energy, etc.), plasma or electron arc or beam
Description: Process which utilizes wave energy (e.g., laser, electromagnetic wave energy, etc.), plasma or an electron arc or beam for (1) modifying or maintaining the internal physical structure (i.e., microstructure) or chemical properties of metal or a metal alloy or (2) in a combined process that includes a step of modifying or maintaining the internal physical structure or chemical properties of metal or a metal alloy, the use of electromagnetic wave energy, plasma, electron arc or beam for any purpose.
