Pulse handheld laser welding machines are widely used in thin sheet metal welding applications due to their advantages of low heat input, minimal deformation, and excellent weld appearance.
However, pulse laser welding machines also have certain limitations. They are not suitable for all materials and products. Before purchasing equipment, users should carefully evaluate their material types, thickness requirements, and welding applications, and conduct sample testing to ensure the machine meets actual production needs.
Currently, pulse handheld laser welding machines are mainly suitable for welding materials such as stainless steel, iron, and galvanized sheets.
Due to the high reflectivity of materials such as aluminum and copper, laser energy absorption is relatively low. During the welding process, energy reflection may occur, resulting in unstable welding performance. Therefore, conventional pulse laser welding machines are generally not suitable for welding highly reflective materials such as aluminum and copper.
In addition, pulse welding has higher requirements for workpiece fitting. Since pulse welding mainly relies on the fusion of base materials and does not support wire feeding, it is not suitable for welding products with large gaps. The welding joints need to be closely fitted to achieve better welding results.
In terms of welding methods, pulse laser welding machines can perform both inside corner welding and outside corner welding. When performing outside corner welding, the corresponding welding nozzle needs to be replaced to achieve better welding performance.
In summary, although pulse handheld laser welding machines offer advantages such as fast welding speed, low heat impact, and excellent appearance, they also have limitations in terms of material compatibility, welding gaps, and process requirements.
Therefore, when selecting a laser welding machine, users should confirm the material type, welding process, and actual application requirements in advance. Sample testing is highly recommended before purchase to verify the welding results and avoid unnecessary investment caused by equipment that does not meet production requirements.
