Laser seam welding is an automated, high-temperature process that uses a laser to create an almost seamless weld between two pieces of metal. The laser directs an intense beam onto one material and then, as the areas of the two materials light up, a second, lower-energy laser offsets the other material and directs a sequence of light pulses on its surface.
Small heat affected zone
Very fast welding
One of the two types is chosen depending on the application. The process is used in both high and low volume applications, such as in the battery and medical industries.
Typical applications of laser seam welding include sensors, radar components, battery housing, conductors for thin film cells, pacemaker cases and insulin pump cases.
