Advantages of the handheld laser welding machine

June 21, 2023

The handheld laser welding machine represents the next generation of laser welding equipment and operates on a non-contact principle. It eliminates the need for applying pressure during the welding process. This innovative device works by directing a high-energy laser beam directly onto the surface of the material. The laser interacts with the material, causing it to melt internally. As the material cools and solidifies, a weld is formed. The introduction of this portable equipment has revolutionized traditional welding methods, providing engineers, manufacturers, and maintenance personnel with efficient, flexible, and convenient welding solutions.


Advantages of the handheld laser welding machine:

  • Cost Reduction: Compared to arc welding, the handheld laser welding machine can reduce processing costs by approximately 30%. It offers straightforward and user-friendly operation, requiring minimal technical expertise from operators. With a short training period, even ordinary workers can achieve high-quality welding results effortlessly.
  • Extended Reach: The handheld welding head is equipped with an original fiber optic cable ranging from 5m to 10m. This overcomes the limitations of workspace, allowing for outdoor and long-distance welding applications.
  • Flexibility and Portability: The handheld laser welding machine features a movable pulley, ensuring a comfortable grip and enabling on-the-go adjustments to the workstation. It eliminates the need for a fixed position, providing freedom and adaptability in various working environments.
  • Versatile Welding Modes: The machine's dual swing head offers diverse welding modes, including spot welding, line welding, circular welding, triangular welding, elliptical welding, semicircular welding, figure-eight welding, and more. This advanced equipment not only supports traditional welding methods but also introduces innovative welding modes to meet different welding requirements. Users can choose the suitable mode for specific applications, ensuring precise and compliant welding results.
  • High Welding Capability: With a power output of 2 kilowatts, the handheld laser welding machine can weld stainless steel and carbon steel up to 6 millimeters thick without the need for additional filler wire. Laser welding, known for its high energy density and penetration, enables powerful welding effects in a shorter time. The device's 2-kilowatt laser power effortlessly handles stainless steel and carbon steel with a thickness of 6 millimeters, eliminating the requirement for additional filler wire.
  • Simplified Process: The traditional image of welding, involving holding a welding helmet in one hand and a filler wire in the other, has been transformed with the handheld laser welding machine. This technology streamlines the welding process, reducing material costs in production and processing.
  • Enhanced Safety Features: The handheld laser welding machine incorporates multiple safety alarm functions. The touch switch only activates when the welding head makes contact with the metal. Upon removing the workpiece, the light automatically locks, and the touch switch includes a temperature sensor. These safety measures ensure the operator's well-being during the welding process.
  • Welding Versatility: The machine enables welding at various angles, including butt welding, corner welding, vertical welding, fillet welding, internal corner welding, external corner welding, and more. It can tackle complex welds and large irregularly shaped workpieces. Furthermore, the device facilitates seamless switching between welding and cutting tasks. By replacing the welding copper nozzle with a cutting copper nozzle, users can easily transition between the two processes.
  • Superior Finishing: Unlike traditional welding, which often requires post-weld polishing for a smooth and refined appearance, handheld laser welding offers notable advantages in terms of processing effects. It ensures continuous welding with a smooth, fish-scale-free finish, delivering an aesthetically pleasing weld without visible scars. As a result, there is a reduced need for subsequent polishing procedures.
  • Enhanced Welding Results: Handheld laser welding operates on the principle of fusion welding. In comparison to traditional methods, laser welding offers higher energy density, resulting in superior welding outcomes. The heat-affected zone in the welding area is minimal, reducing the likelihood of deformation, discoloration, and marks on the backside. The process achieves substantial welding depth and sufficient fusion, leading to strong and reliable welds.
