Handheld Laser Welding Machine: The Basic Guide

In the laser welding field, traditional welding requires skilled welders and high flux costs. Moreover, the workpiece needs to be processed twice after the welding is completed. In order to solve these problems, handheld laser welding machines have been produced.
The handheld laser welder uses a laser beam as the energy source, and this new welding technology is more convenient. This new welding technology is more convenient and has the advantages of beautiful weld seams, small heat-affected areas, fast welding speed, and so on.
Handheld welding replaces traditional welding processes such as electric and argon arc welding. The industry's sheet metal and irregular welding process is used widely.

What is a handheld laser welding machine?

The handheld laser welding machine uses non-contact welding technology. The laser beam melts the material instantly without applying pressure, then cools and solidifies to form a strong weld. The handheld laser welding machine revolutionizes the traditional laser welding model by bringing the flexibility of a fixed light path out of the handheld.
And you can weld anywhere, anytime, no longer affected by the environment and the angle of the workpiece.
When welding stainless steel, iron, aluminum, copper, carbon steel, and other metal plates, the welding heat-affected area is small, the weld is beautiful and strong, and the laser welding machine is easy to operate and has fast welding speed.

Working principle of handheld laser welding machine

The handheld laser welding machine's welding principle is based on using high-energy laser pulses to heat specific areas of the material. The powerful energy of the laser beam instantly melts the material, which then cools and solidifies to form a weld. Compared with traditional welding methods, laser welding has the advantages of high efficiency, high precision, no additional filler material, and low impact on the workpiece.

Why use a handheld laser welding machine

Handheld laser welders are ideally suited for large workpieces. The greatest advantage of laser welding is the robustness of the weld seam and the small heat-affected area. During the welding process, it is guaranteed that the workpiece will not be bent, deformed, blackened, or other welding faults. You can easily weld at any angle or position, suitable for large workpieces or machines that are difficult to move.
At the same time, faster laser welding can save a lot of time and cost and also improve the quality and reliability of welding. 

Advantages of Handheld Laser Welding Machines

Handheld laser welding technology is famous for its easy operation, beautiful weld seam, fast welding speed, and no need for consumables.
And it can perfectly replace the traditional welding process, such as argon arc welding, electric welding, etc., for thin stainless steel, iron, galvanized sheet, and other metal materials.
The handheld design of the laser welding machine is crucial in practical applications, making it the best choice for workshops that perform small-scale processes or non-mass welding.
Welding products with diverse and flexible shapes are fully catered for by handheld laser welding.
The handheld laser welding machine uses a handheld torch instead of a fixed optical path, completely changing the previous working mode of the laser welding machine.
This operation mode facilitates mold welding, advertising signs, kitchenware, and other products and allows outdoor laser welding.

Wide welding range:

The handheld welding machine is equipped with 5m-10m original fiber optic, eliminating the limitation of workbench space and achieving outdoor remote welding. And the handheld laser welding machine has mobile pulleys, which can adjust the workstation at any time without needing a fixed workstation. This makes it suitable for a variety of working environments and scenarios.

Multiple welding methods:

The handheld laser welding machine can work at any angle, including lap and flat fillet welding, joint welding, internal fillet welding, vertical welding, butt welding, external fillet welding, and so on.
It can handle the welding of large workpieces with complex and irregular shapes. And it provides higher energy density, which produces excellent welding results.
The weld area is subject to minimal thermal influence and is less likely to be deformed or blackened.
No need for re-machining
Traditional welding often requires polishing to ensure a smooth surface free of roughness. Handheld laser welding, on the other hand, provides a continuous, smooth weld seam without fish scales, scars, or the need for subsequent polishing.

Reduced costs:

Handheld welding reduces material costs in manufacturing processes. Handheld laser welding can reduce process costs by up to 30 percent compared to arc welding. It is also easy to learn and requires only simple training to produce high-quality weld results.

Handheld Laser Welding VS Conventional Welding

As the economy advances and welding technology improves, there are a variety of welding methods available for individuals to choose from
Unlike traditional welding equipment, more and more consumers in the modern manufacturing industry choose laser welding machines.
So is handheld laser welding really that good? To help you better understand the features of this product, I would like to highlight the differences between laser welding and conventional welding.
Conventional welding usually requires burying and preheating the welded joints.
This method is cumbersome and suffers from disadvantages such as easy distortion, broken weld joints, and corrosion.
So far, it is rarely used.
A handheld laser welding machine is easy to operate, flexible, and convenient, and the welding range is farther. And it is mainly used for long-distance laser welding.
The biggest difference is that the laser-welded workpieces are hardly deformed and need not be cleaned up after welding.

Handheld Laser Welding Applications

Handheld laser welding can be used in many applications, including automotive, aerospace, medical devices, electronic equipment, and more. You can use it to weld metallic materials such as steel, aluminum, copper, and magnesium, as well as plastics and other non-metallic materials. Handheld laser welding has the advantages of high efficiency, precision, and non-destructive, which can improve productivity and product quality.

Challenges of Handheld Laser Welding Machines

  1. Restricted welding area: Handheld laser welding requires the operator to hold the welding gun for welding, so the welding area is somewhat restricted, making it difficult to carry out welding operations over a large area.
  2. Welding quality: Influenced by the operator's skills, handheld laser welding requires a certain level of skill and experience on the operator's part. Otherwise, the quality of the weld will be affected.
  3. Safety issues: laser is a high energy radiation. If not used correctly, it may cause harm to the human body.
  4. High cost of equipment: Handheld laser welding equipment is relatively costly and requires a large investment.


Handheld laser welders offer numerous advantages, including high precision, excellent weld quality, and minimal heat release. They are fast and efficient, resulting in shorter production times and lower labor costs. In addition, they are suitable for a wide range of materials and applications, making them versatile tools for the welding industry. You can leave a message if you want to know more about them.
