Class Information
Number: 148/565
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 > Heating or cooling of solid metal > Utilizing wave energy (e.g., laser, electromagnetic, etc.) plasma or electron arc or beam
Description: Process which utilizes wave energy (e.g., laser, electromagnetic, etc.), plasma or electron arc or beam for (1) modifying or maintaining the internal physical structure (i.e., microstructure) or chemical properties of metal or metal alloy or (2) in a combined process including a step of modifying or maintaining the internal physical structure or chemical properties of a metal or metal alloy, the use of wave energy, plasma, electron arc, or beam for any purpose.
