With the development of science and technology, the welding industry is becoming more and more advanced, and users are also discussing the products of laser soldering machines. Today we will discuss why laser automatic soldering machines are better than handheld laser soldering machines.


Handheld laser welding machines use high-energy laser pulses to locally heat materials in small areas. The energy radiated by the laser diffuses into the interior of the material through thermal conduction, causing the material to melt and form a specific molten pool. Handheld laser welding machine can be used for welding larger products in industries such as cabinets, kitchens, shelves, ovens, stainless steel door and window guardrails, etc. Not suitable for precision welding, slow welding speed, manual operation required, low welding efficiency.


Disadvantages of handheld laser welding machine


During the crack laser welding process, due to the small laser heat input, welding deformation, and welding stress, high-temperature cracks generally do not occur. However, due to different raw materials and improper selection of process parameters, high-temperature cracks may sometimes occur.


2. Removal and Weldability Changes When performing laser beam welding from medium to high energy, a plasma controller should be used to remove ionized gases around the molten pool to ensure the reproducibility of the weld seam. Moreover, when welding materials with high reflectivity and high thermal conductivity, such as aluminum, copper, and their alloys, laser will alter their weldability.


3. After laser welding with spatter, many metal particles may appear on the surface of some workpieces or data, which not only affects the appearance but also affects the application. The reason for this phenomenon is that there are stains on the surface of the workpiece or data, which may be the galvanized layer.


When the trajectory of the weld seam changes significantly, it is easy for the thin film to have burrs or unevenness at the corners. The reason for this phenomenon is that the weld trajectory changes greatly and the teaching is uneven. At this point, it is necessary to adjust the welding parameters and connect the excess corners for processing.


Laser automatic soldering machine can effectively solve these pain points. Advantages of laser soldering machine:


1. The laser soldering machine adopts non-contact welding and is stress free;


2. The laser welding machine adopts non-contact heating, with a wide melting band and no need for any auxiliary tools. It can perform post-processing on double-sided components on double-sided printed circuit boards without static electricity threat.


3. Good stability in repeated operations. Flux causes minimal pollution to welding tools


The welding speed of laser soldering machine is three times that of ordinary soldering machine.


5. Without space limitations, laser soldering machines can weld narrow areas and micro components


6. The laser soldering machine has no damaged welding joints and fewer consumables


7. It can achieve automated visual programming and is easy to implement automation


8. Laser soldering machines have a long service life, low power consumption, and low maintenance costs. Application areas of laser soldering machine: Laser soldering machine can be widely used in the medical, military, and automotive electronics industries. It has more obvious advantages in areas that cannot be solved by traditional soldering iron soldering, such as temperature sensitivity of soldering heads and welding equipment, and high automation requirements. Meanwhile, laser wire feeding welding can replace traditional manual welding and achieve automated production. The wire feeding solder of laser soldering machine is suitable for products with large solder joints such as printed circuit boards, FPCB boards, and terminal blocks; Meanwhile, due to the better controllability of laser energy, traditional high heat dissipation materials can be welded.
