A laser welding machine is a high-precision welding system that uses a focused laser beam to join metals or thermoplastics. It is widely used in automotive, electronics, aerospace, medical devices, jewelry, and manufacturing industries where accuracy, speed, and minimal heat distortion are critical.
How It Works
The machine generates a concentrated laser beam that melts and fuses materials at the joint. Because the heat is highly localized, surrounding areas remain largely unaffected, resulting in strong and clean welds with minimal deformation.
