A laser welding and cutting machine is a dual-function industrial tool that combines high-powered laser technology to cut and join metal or thermoplastic materials with extreme precision and efficiency. These machines are widely used across sectors like automotive, aerospace, electronics, jewelry, and heavy machinery manufacturing.
Key Takeaway: Laser systems offer non-contact, high-speed, and low-deformation processes, making them ideal for modern industrial applications.
How Does It Work?
Laser Cutting:
Uses a high-powered laser beam to melt, burn, or vaporize material.
Often paired with assisting gases like nitrogen or oxygen to improve cut quality.
Controlled by CNC systems to follow exact dimensions and intricate designs.
Laser Welding:
Concentrates a narrow, high-intensity laser beam to melt the materials at the joint.
Can weld with or without filler material.
Produces deep, narrow welds with minimal heat-affected zones (HAZ).
