What Is Laser Welding Machine?

A laser welding machine is a power welding tool that uses a laser gun, a CNC controller, or a single-arm robot to join metals or thermoplastics together. In addition to spot welding, laser beams also provide a concentrated heat source, which is ideal for welding butt joints, lap joints, lap edges, laps, T butts, seams, narrow welds, deep welds, and kissing welds with high welding rates. Automation is often used in high volume applications, which use keyhole or penetration mode welding.

Welding machines powered by engines are called laser welding machines. They can be used to weld very small parts together in the engineering, medical, and electronics industries, as well as thicker materials in the aerospace and automotive industries. Using laser welding, you can create high quality spot welds for different materials and thicknesses at a low cost.

In addition to laser welding machines, laser beam welding machines are also commonly known as laser welders, laser beam welders, laser beam welding machines, laser beam welding equipment, laser beam welding guns, laser beam welding tools, seam welding machines, laser bonding machines, laser brazing machines, laser joining machines, and laser soldering machines.

The working principle of fiber laser welding machines

Pump light will be absorbed by rare earth ions as it passes through the optical fiber. In order to achieve the inversion of the ion number, rare earth atom electrons will be excited to higher laser energy levels when they absorb photon energy at this time. Radiation will transfer the reversed ion number from the high-energy level to the ground state, releasing energy to complete the stimulated radiation process. As soon as the laser produced by the optical fiber laser welding machine is output through the optical fiber, it is matched with the supporting workbench to complete the welding process.

There are two types of fiber laser welding machines: pulse fiber laser welding machines and continuous fiber laser welding machines. In the pulse fiber laser welding machine, the laser peak power, frequency, and pulse width can be set to adjust the laser pulse single point energy; in the continuous fiber laser welding machine, the laser power can be adjusted by setting the average laser power.

What are the benefits of laser welding?

There are several reasons to choose a laser welding machine:

1.   Their speed is relatively fast:

Due to this technology’s ability to rapidly heat metal while minimizing the risk of deformation, it is widely used in the automotive industry for welding large amounts of sheet metal.

2.   It is also technically correct

The laser beam can be split into several beams for more accurate welding, allowing for localized, very fine, very clean, almost invisible welding. They are particularly good for welding small parts. The dental and jewelry industries prefer this type of welding because it provides the most aesthetically pleasing welding.

3.   The machines are flexible enough to accommodate a wide variety of part sizes, shapes, and materials.

Laser welding machines are primarily used to weld metals, including refractory materials. They can also be used to successfully weld materials that aren’t metal, like ceramics and glass. Pieces of widely varying shapes and sizes can be joined together using them.

4.   There is no way to break them:

By eliminating tool and electrode changes, laser welding reduces waste and protects equipment from unnecessary wear and tear. There is no physical contact between the two pieces that are being welded with laser welding machines.

5.   Digital orders can be given to them:

With the use of a computer to monitor and adjust weld quality in real time, productivity is greatly improved. Such a process also allows for great deal of automation, which ultimately allows for quality issues to be identified and corrected.
