Brazing & Soldering
Fiber lasers bring alternatives where some materials can not be joined using a traditional process.
Aluminum and steel are good examples: those two metals have different melting points and are difficult to solder. When the laser heats the surface the filler melts and flows to create a bond between two materials.
Brazing and soldering processes are currently widely used in automotive, heavy industry, consumer electronics and photovoltaic industries. The high quality and precision of fiber lasers minimize the post-processing cost as the cool-down time is greatly reduced and the parts are immediately available. Thermal effects and distortions are minimized as the material heating is localized only to beam spot.
