3 in 1 Handheld Laser Welder Function Overview

Laser welding is a welding technique that uses a focused high-energy laser beam to melt the material with extremely high spot precision and solidify it with cooling to form a specific weld seam.

The three-in-one laser welding machine combines laser welding, laser cleaning and laser cutting in one machine. So it is now loved by more and more customers in the industry.

The hand-held welding torch is highly flexible and is not limited by the shape of the workpiece. In addition, the three-in-one welding machine is compact and easy to move, which can meet the needs of mobile on-site processing. It is widely used in home appliances, automotive electronics, cell phone manufacturing, household appliances, IT products, instrumentation, precision machinery and other industries.

In this article, we will briefly introduce the three functions of the 3-in-1 handheld laser welder.

Laser Welding

Is the welding speed different for different power? Is there a difference in the welding effect?

Since the principle of laser welding is to melt the material by heat, the higher the laser power, the faster the material will melt. Besides, the higher the power, the higher the efficiency which means the faster the speed.

Take the welding of carbon steel as an example:

1.5KW laser power can weld 2-2.5mm thick;

2KW laser power can weld 3-4mm thick;

3KW laser power can weld 5-6mm thick.

How to solve the case of wide weld seam?

We offer a free wire feeder for wider welding seam to ensure firm welding.

How to choose the welding wire? How thick is it?

  • The material of the wire must be consistent with the welding material. So the welding color is consistent and the welding effect is better.
  • The diameter of the wire needs to be smaller than the thickness of the material to ensure that the material will not be melted through after the wire is melted.
  • Do not use aluminum wire even if you need to weld aluminum. Because the aluminum wire is relatively soft. It will bent during feeding. You can try the aluminum-magnesium wire.

When welding, the machine comes with ground clips, and the two ends are connected before welding, otherwise no laser beam will come out.

How to choose between single-sided welding and double-sided welding?

Normally, you can choose single-sided welding if the laser power is large enough. Because the welding efficiency is high. Besides, the single-sided welding is more suitable for inner surface welding with good welding effect. But if the welded material is too thick, you can choose double-sided welding.

For example, the maximum welding capacity of2 kW handheld laser welder is 4mm. If you need to weld 5mm material, you can consider double-sided welding to ensure the welding effect. However, if you weld materials with a thickness of 7-8mm, even double-sided welding can not ensure firm welding effect. In such case, we recommend the 3kW handheld laser welding machine.

Laser cleaning

The cleaning function of a 3-in-1 laser welder mainly services for welding. You can use it to pre-treat the welded parts to ensure better welding effect and solid welding. Besides, you can make the welding surface smoother and more conducive to the subsequent spraying or painting after welding.

The cleaning width of the 3-in-1 handheld laser welder is fixed at 80mm. So if your major purpose is to use it for laser cleaning, you need to check if the 80mm width is acceptable.

DXTECH Asia also has professional laser cleaning machines with a cleaning width of 200mm. They are specifically for laser rust removal and laser paint removal.

Laser cutting

The cutting function of the 3-in-1 welding machine is, in fact, rather limited. The cutting path can only be grasped by both hands, and can only cut in a straight line. In addition, it cannot cut curves or patterns. Therefore, it is not suitable for high-volume cutting work.

It can pre-save cutting parameters as well as welding function to avoid repeated input.

Do the three functions use one cutting head?

The welding and cutting modes share a common handheld cutting head, but require nozzle replacement.

When changing to cleaning mode, the focus mirror must be replaced in addition to replacing the nozzle.

What are the wearing parts of a 3-in-1 laser welding machine?

Protective lenses and nozzles.

There are two protective lenses inside the handheld gun: the upper and the lower protective lenses. In which, lower lenses is easy to wear. Its main function is to prevent the smoke and dust generated during work into the interior of the laser head to contaminating the optical path, resulting in burning other lenses and laser head.

The service life of the protective lenses is about 15 days, depending on your specific processing needs and the degree of operational specifications.

Is it safe to use the 3-in-1 handheld laser welding machine?

DXTECH Asia offers you a set of protective glasses and helmet free of charge at the time of shipment. They can prevent you from laser damage when operating the machine. In addition, the machine must be operated with certain external devices. Besides, the power and parameters of these external devices must be compatible with the machine.

In case you don’t know how to choose the external devices, DXTECH Asia provide you with all these devices for free when the handheld laser welder is shipped. You can use them directly after you receive it, without purchasing them additionally. This saves you a significant amount of money.
