…these established laser processes all
create marks via a photothermal process. In short, a tightly focused laser beam delivers
intense heat in a highly localized manner, raising the material temperature to produce some
type of change. For example, a CO2
laser marks various…

heating can cause part distortion, resulting in the need for major postprocessing machining. Moreover, when cladding with powder, capture rates of approximately 80 percent are typically achieved. In contrast, laser cladding can deliver most of the advantages of thermal spraying and arc welding, with

consistency. The problem usually arises because stainless steel absorbs the near infrared fiber
laser output more strongly than the longer CO2
laser wavelength. This high absorption causes
more rapid material heating, which is also confined to a smaller region, both of which lead…
