Green Lasers Aim to Weld Red

From Miyachi Unitek Corporation
 

 

Welding pros know that lasers offer flexible configurations and a high degree of process control, making them ideal for numerous applications. Yet the inability of conventional laser technologies to handle "red" metals like cooper and gold has blocked their use in many industrial applications. That's about to change with the advent of 532-nanometer (532 nm) green welding laser technology.

The interaction between laser light and welded materials depends on the wavelength of the light and on the base materials. For example, CO2 lasers with wavelengths near 10 microns interact well with organic materials such as plastics, wood or rubber. Also, fundamental-mode 1064 nanometer pulsed Nd:YAG lasers interact well with non-copper metals such as stainless and cold-rolled steel, high nickel alloys and some aluminums.
