In laser beam welding, materials melt
under the heat obtained from a narrow beam of coherent, monochromatic
light (a laser beam). Typically, no filler metal is used.
Process Characteristics
Is used for thin-gage workpieces
Is used for welding areas that are not readily
accessible
Provides excellent welding precision
Permits joining of dissimilar alloys
Uses no electrodes
Causes little or no thermal damage to the workpiece
