What is a laser welding machine?

A laser welder is one of the laser processing machines used to weld and cut metal. The laser beam injects energy into the workpiece, melts it in a very short period of time and solidifies it quickly, reducing distortion after welding. Another feature is that it processes faster than conventional welding methods. In addition, fine processing is possible by adjusting the wavelength, energy density and spot diameter of the laser.

Laser welding is a process used to join metals or thermoplastics using a laser beam to form the weld seam. As a concentrated heat source, laser welding can be performed at high welding speeds of several meters per minute on thin materials, while on thicker materials, narrow, deep welds can be produced between parts with square edges.

Currently, there are three main types of sources of laser for laser welding machines that use one of these laser sources i.e. Fiber laser, CO2 laser, and Nd: YAG laser. Each of these laser sources has their own benefits and are suitable for the different types of welding materials.

Fiber Laser Welding Machine

The fiber laser welding machine is ideal for working on metallic parts. Furthermore, it offers great reliability and efficiency. According to estimates, the accuracy of the laser welding machine using fiber laser is close to 25%.

CO2 Laser Welders

The CO2 laser welders can provide a great continuous welding beam that creates efficient and durable welds. It can easily penetrate metals and non-metallic bodies.

Nd: YAG Laser welders

The Nd: YAG lasers are less energy efficient as compare to the fiber laser welding machines. However, there are certain applications like greater laser control that you cannot achieve with other types of laser sources.

Summing up, you will get laser welders of all types, technologies, and sources. You will have to decide which type of laser welder will suit your business the best.
