● Various welding methods
It can achieve welding at any angle, such as lap welding, butt welding, vertical welding, fillet welding, inside corner welding, outside corner welding, etc. It can be used for welding various complex workpieces and large irregularly shaped workpieces, achieving welding at any angle. Additionally, it can also perform cutting, and the welding and cutting functions can be freely switched. It is very convenient to change the welding copper nozzle to the cutting copper nozzle.
● Good welding effect
Handheld laser welding is a thermal fusion welding method. Compared to traditional welding, laser welding has higher energy density, which can achieve better welding results. The heat-affected zone in the welding area is small, making it less prone to deformation and discoloration, with visible traces on the backside. It has a large welding depth, complete fusion, and strong reliability, with weld strength that can even exceed the base material itself, which cannot be guaranteed by ordinary welding machines.
● No need for welding table setup
Laser welding machines do not require the setup of a welding table during processing, occupying less space. In response to the diversification of welding products and the flexible and variable shapes of the products, handheld laser welding machines can fully meet the needs of such production. Handheld laser welding machines do not require a precision welding workstation, resulting in low material and energy consumption, as well as low equipment deployment and maintenance costs.
● Easy operation
Handheld welding does not require a welding certificate. Basic training and understanding of the parameters are sufficient to get started. Nowadays, handheld welding equipment is operated through intelligent control systems. By modifying the parameters on the touch screen, it can achieve welding of different materials, showing strong adaptability to materials.

Remark: Double weld thickness can be achieved if the material is welded from both sides in two times.
● Cutting: Welding and cutting are often inseparable. Laser welding machines combine the functions of the two. Laser welding machines can be used to laser cut metal materials, such as copper plates, aluminum plates, stainless steel plates, carbon steel plates, galvanized plates, etc. Meet the cutting needs of conventional thin plates.
● Cleaning: Cleaning with a laser welding machine is easy and flexible, and can remove rust, oxides, grease, dirt, etc. on the surface of various workpieces. When using a handheld laser welding machine for cleaning, it is necessary to avoid harm to the human body caused by the laser beam.
● Weld bead cleaning: It can effectively remove oxides, welding slag, oil, dust and other impurities produced during the welding process, making the weld surface clean. This not only helps improve the quality of the weld, but also enhances its strength and appearance. Laser cleaning is highly precise and controllable, thoroughly cleaning the weld surface without damaging the base material.
A wide range of welding methods are available for welding at any angle, including overlay, butt, vertical, fillet, internal, external, etc. These methods can be used for a variety of workpieces, including complex welds and irregularly shaped workpieces, especially larger ones. These methods can be used to weld a wide variety of workpieces, including complex weld seams and irregularly shaped workpieces, especially larger workpieces.
