Brazing & Soldering

Brazing and soldering are metal joining processes

in which a filler metal joins dissimilar

materials. Depending on the

substrate materials and their subsequent

filler materials used, these processes

utilize lasers to melt the filler

metal in a controlled and remote

process. Laser brazing and

soldering are often used on

finished components in the

automotive and consumer

electronics industries.


Components that cannot be joined together via traditional welding processes may use brazing or soldering as an alternative. Brazing is a metal joining process in which the filler metal such as copper or zinc has a melting point higher than 425°C but lower than that of the metal substrates. As the laser heats the substrates and melts the braze, the gap between the substrates acts as a capillary for the braze to flow and bond with the substrate. IPG's high power fiber lasers are an ideal solution for brazing applications in the automotive and heavy transport industries.  

In a related process, soldering is similar to brazing except that the filler metals melt at temperatures below 425°C. Soldering is often used for bonding dissimilar materials such as aluminum and steel due to their different material melting points. Soldering applications use IPG's mid-power fiber lasers for the consumer electronics, automotive and photovoltaic industries.
