Classification of Laser Welding Head

Fiber Laser Welding Head
A fiber laser welding head is a device that focuses a laser beam onto a welding site. The laser beam melts metal, which then solidifies into a strong weld.

Handheld Laser Welding Heads
A handheld laser welding head is a small, lightweight device that uses a laser beam to join materials. They are often used in industries like automotive, aerospace, and electronics.

High Power Fiber Laser Welding Head
A high-power fiber laser welding head is a tool that uses a laser beam to join pieces of metal together. It's a versatile tool that can be used for a wide range of welding applications.

Functions of Laser Welding Head

●This welding joint has strong advantages in aluminum alloy welding and medium power welding applications, and is an economical and efficient welding joint.

●The welding head adopts motor driven X and Y axis galvanometer lenses, with multiple swing modes, and swing welding allows irregular welding of workpiece, larger gap and other processing parameters, which can significantly improve the welding quality.

●The internal structure of the welding joint is completely sealed, which can prevent the optical part from being polluted by dust.

●The protective lens adopts a drawer structure, which is easy to replace.

●It can be equipped with various lasers with QBH connectors.

Tensile Test of Laser Welding Head

The tensile test is done in the initial state to test the weld metal performance. It is done to determine the best filler metal for the laser welding application. A demo piece of the exact same measurement is loaded and stretched to test the tensile strength and ductility of the weld.

After the test, the tensile strength is displayed. Manufacturers perform tensile strength testing procedures per the specific requirements of the base metal plates.

Tensile tests can be conducted in various ways. One, you can pull apart the laser weld until it reaches a breaking point. Secondly, you can place it in shear until it reaches its extreme breaking point. You can also do a compression test to check the tensile strength of the laser welding joint.

FAQ

Q: What are the key components of a fiber laser welding head?

A: The key components of a fiber laser welding head typically include a collimator to make the diverging laser beam from the fiber optic cable parallel, a focusing lens to focus the beam onto the workpiece, a protective window to prevent contaminants from entering and damaging the internal components, a nozzle to direct shielding gas onto the welding area to protect the weld pool from oxidation, and a housing to hold all the components in place and provide mechanical support.

Q: What are the parameters for laser welding head?

A: Laser welding head process parameters mainly include laser power, welding speed, shielding gas flow, pulse rate, focal distance and gap. Two main process parameters that affect the weld bead the most are laser power and welding speed.

Q: How do you select the appropriate fiber laser welding head for a specific application?

A: When selecting a fiber laser welding head, consider factors such as the power and wavelength of the laser source, the material and thickness of the workpiece, the required welding speed and quality, the available space and setup requirements, and the type of joint to be welded. If working with high-power lasers, the welding head should be able to handle the heat and power density.

Q: What is the main function of a fiber laser welding head?

A: The main function of a fiber laser welding head is to focus and direct the laser beam from a fiber laser source onto the workpiece to create a high-quality weld by melting and fusing the materials together. It also helps in controlling the laser beam parameters, and focal length to achieve optimal welding results.

Q: How can you maintain and clean a fiber laser welding head?

A: Regular maintenance of a fiber laser welding head includes checking and cleaning the protective window regularly to remove any dirt, debris, or spatter that may accumulate and affect the laser beam transmission. The nozzle should also be cleaned to ensure proper shielding gas flow. Inspect the components for any signs of damage or wear, and replace parts like the focusing lens or nozzle if necessary. Additionally, keep the welding head in a clean and dry environment when not in use.

Q: Can a fiber laser welding head be used for different types of materials?

A: Yes, a fiber laser welding head can be used for a wide variety of materials, including stainless steel, aluminum, copper, titanium, and many alloys. However, the welding parameters such as power, pulse frequency, and welding speed need to be adjusted according to the specific material properties.

Q: What are the safety considerations when using a fiber laser welding head?

A: When using a fiber laser welding head, safety is of utmost importance. Operators should wear appropriate personal protective equipment, including laser safety glasses that are rated for the wavelength of the laser being used to protect the eyes from the laser beam. The welding area should be properly enclosed to prevent accidental exposure to the laser light. Ensure good ventilation to remove fumes and gases produced during welding.
