Handheld laser welding is a new welding method that has emerged in recent years, and it is also a new application attempt of laser in industrial production. Its principle is to rapidly heat up the workpiece locally to melt through a highly energy dense beam, forming a molten pool and achieving welding effect. Compared to traditional welding, handheld laser welding has advantages such as high efficiency, good weld quality, and low manual dexterity.
Handheld laser welding equipment has significant differences compared to traditional welding equipment, and its main structure includes:
Laser: The laser generates a laser beam and is the core component of handheld laser welding equipment. According to the required laser type, the laser generator can be a fiber laser, carbon dioxide laser, or solid-state laser. The type and power of the laser are the main factors that directly affect the welding effect and the materials used.
Optical system: After the laser emits a beam, it is transmitted to the welding head by the optical system. The optical system for handheld laser welding usually includes lenses, mirrors, light rays, etc. High quality optical systems can optimize the focusing of laser energy and ensure the welding effect.
Handheld welding head: also known as handheld welding gun, it is the final place where the laser beam emits light. The operator holds the welding head to guide the laser beam to focus on the desired welding area, and then completes the welding work. Welding joints typically include lenses, mirrors, wire feeders, etc., to control the size of the focus and wire feeding.
Control system: The control system for handheld laser welding is usually an embedded controller, which includes a display screen with a user interface. The operator adjusts parameters such as laser power, welding speed, path, and time in real time through the user interface. The control system will also monitor various indicators of the equipment in real-time during the welding process, and issue alarms in case of abnormalities to ensure safe processing.
Cooling system: The laser generates high temperatures during operation, and a specialized cooling system is required to prevent overheating of the equipment. There are two types of cooling systems for handheld laser welding: air-cooled and water-cooled, which are mainly selected based on the different laser powers.
The coordination and cooperation of various components of handheld laser welding equipment are key to achieving efficient, stable, and safe welding. These components work together to ensure smooth welding processes and improve welding quality. Different manufacturers may have different configurations and designs, but the components listed above are usually the basic components of the relevant equipment.
