The beam welding or LBW process involves the joining of two metals or thermoplastics with the help of a beam. In other words, metals joined together using the laser beam to form a strong weld. Laser beam welding includes the high amount of heat source passed on to the thin materials. This lightweight material gives better response to beam welding. Thus, the welding is carried out on them at a very high welding speed per minute. The laser beam welding process involves the two fundamental modes. Firstly, the limited conduction welding and the other one is keyhole welding. However, the thermal conduction process plays an essential role in beam welding. Therefore, titanium metal welds easily in low laser energy as compared to gold.
Beam welding or LBW becomes one of the critical and popular manufacturing methods. Due to its extensive use, various applications are now carried out using laser beam welding.
Laser Beam Welding Working Principle
Beam welding or LBW works on the principle of electrons. To clarify, a particle of any atoms gets excited and starts absorbing energy. Then, they return to their ground state by an emitting photon of light. Furthermore, the concentration of these photos increases when there is an emission of radiation. Finally, we get to see a highly concentrated laser beam.
To start the laser welding, you should place the setup of a welding machine at your desired point. Moreover, adjust the high voltage setup, then apply it on the laser machine. Doing this will emit light photons and start the flash of the lamp. The energy of these light photons gets absorbed by ruby crystal atoms. Thus, they move to an excited state. After returning from the excited state, these photons emit light. The laser beam welding process starts by focusing the laser beam on the desired area. Workers use the lens to focus more precisely. CAM parts of the beam welding control the necessary motion of the laser. Besides, when the laser beam strikes between the two metal cavity and fuses them. Thus, it generates a strong weld, and we use beam welding.
Parts Involved In The LBW Process
The essential elements that are involved in beam welding include laser machine, power source, and CAM. Shielding gas and CAD are significant types of equipment for beam welding.
Why Should You Use Laser Beam Welding?
Beam welding has many uses and advantages over any other type of welding. Using beam-type welding or LBW, you can produce the right weld quality product. It also automates the robotic based machinery to generate high volume production in another welding where it takes considerable time to weld the thick section. When using beam welding, this time gets reduced, and you get the desired output. Moreover, you can easily weld it in the absence of a vacuum.
Metals having different properties can be readily welded using beam welding. Furthermore, this welding includes a wide aspect ratio. In other words, beam welding has a 10:1 aspect ratio. Seeing all these advantages, the companies majorly use this process in automobile sectors. Moreover, the place where large volume production is carried out, you can use beam welding or LBW.
