Laser welding is one of the important aspects of the application of laser processing technology. The surface of the workpiece is heated by laser radiation, and the surface heat diffuses to the interior through thermal conduction. By controlling parameters such as the width, energy, power density and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully used in the welding of micro and small parts. The emergence of high-power CO2 lasers and high-power YAG lasers has opened up a new field of laser welding. The deep penetration welding based on the pinhole effect has been obtained, and it has been widely used in industrial sectors such as machinery, automobiles, and steel.

Shandong Jiabang Laser Handheld Laser Welding Machine adopts the latest generation of fiber lasers and is equipped with self-developed welding heads to fill the gap of handheld welding in the laser equipment industry. It has the advantages of simple operation, beautiful welding seam, fast welding speed and no consumables. Welding of thin stainless steel plates, iron plates, galvanized plates and other metal materials can perfectly replace traditional argon arc welding, electric welding and other processes. Hand-held laser welding machine can be widely used in complex and irregular welding processes in cabinet kitchen and bathroom, stair elevator, shelf, oven, stainless steel door and window guardrail, distribution box, stainless steel home and other industries.
