In some ways, laser welding is better than using traditional tools to do the job. It can be done with a laser to make a “keyhole.” A keyhole lets heat get in through the material. A lot of people like this because:

Using a laser to weld saves a lot of time. People can weld thin materials with the right type and power of the laser. They can weld them at speeds of several meters per minute. Lasers can be used in very automated places and have a lot of people working at the same time. Also, the laser keyhole welding process can be used to weld thicker parts in a single pass instead of having to weld them over and over again with other welding methods. Nd: YAG, diode, fibre, and disk lasers, in particular, send out optical fibre beams that can be easily moved by multi-axis robotic delivery systems, allowing for a flexible manufacturing process.

Welds are made with a lot of detail.

JNCT LASER welding makes it possible to make welds with a lot of surface area (considerable depth to narrow width). Laser welding can be used to weld joint configurations that aren’t possible with other welding methods, like welding through lap joints. With this method, you can use smaller flanges than you can with resistance spot welding because this method doesn’t use heat. The average laser welding machine price is almost 52,800 $.

little heat and little distortion

It is possible to make a keyhole with a laser because it can produce a focused heat source. Because of this, laser welding only makes a small amount of weld metal and doesn’t heat the surrounding material as much as other welding methods. This means that the sample will be less distorted. The heat-affected zones on both sides of the weld are also smaller because of the low heat input. This means minor damage to the parent material and less loss of its properties.

Materials and thicknesses of all kinds can be used.

There are a lot of different materials that can be welded or joined together with the help of laser technology. This includes metal, polymers, and textiles, among other things. The thickness of materials that can be welded varies depending on the type and power of the laser.Laser welding doesn’t need to be done under high pressure like most electron beam keyhole procedures. However, gas shielding is often needed to prevent the welds from oxidizing.

A single-sided, non-contact way to do things

Because of this, there isn’t any force on the workpieces being joined during the laser welding process, and the process is usually one-sided. Some fusion procedures might need to shield the weld root, like in many other types of welds.

Welding that doesn’t go on for a set amount of time

As long as the weld is good for what it’s supposed to do, lasers can be used to make a simple spot or stitch welds.


Welding isn’t the only thing that lasers can be used for. They can also be used for cutting or surface or heat treatment, or even branding. It’s also possible to think about the beam delivery method in a lot of different ways, like the following:

The use of a single laser beam to do a lot of different things simultaneously in a lot of different welding stations.It can be used to process two different parts of a workpiece (or the same area from two different sides) simultaneously because the laser beam can share its power.

The transmittance or focusing optics can be used to shape or split the laser beam so that it can be used to work on different types of materials with different amounts of energy.
