Paper Abstract

The ability of continuous wave high power CO2 Lasers to generate power densities of up to 108 watts Cm makes them useful for a variety of material processing tasks. Deep-penetration laser welding, high precision laser cutting, surface heat treating by martensitic phase transformation hardening, and surface alloying are the four major areas which are accepting laser processes. This paper will cover these four primary laser applications existing in production within a variety of industries. Each individual area will be discussed in detail, describing the advantages and various parameters to achieve maximum productivity and quality. Beam config-uration, integration, and manipulation are included also. Production examples of laser welding, cutting, surface hardening and surface alloying, are examined to demonstrate the laser processing advantages. This paper also reviews the present and future status of the laser metalsworking industry in respect to the growth potential, research and development, manufacturers responsibilities etc.
