A Handheld Fiber Laser Welding Machine is a new type high-power, high-end continuous welding tool which adopts a high-quality fiber laser source to produce a fiber optic beam. After transmission processing, the light is focused on the workpiece to achieve continuous welding. It avoids the two thresholds of thermal strain and post-treatment, and is environmentally friendly and pollution-free, greatly improving the joint strength and quality of welding.
Replacing the previously fixed light path with a hand-held type not only facilitates the welding of molds, advertising characters, kitchen utensils, doors and windows, etc., but also makes laser welding possible in outdoor operations, which indicates that the traditional welding of electric welding, argon arc welding, etc. will be replaced by laser welding.
Traditionally, laser welding is done with a fixed welding head with a higher power laser having lower beam quality to give acceptable weld widths as single mode beams are too sharp leading to very narrow weld profiles.
In contrast wobble welding (or oscillation welding) is where a high beam quality laser is used with a galvo scan-head to rapidly oscillate the focal spot.
This method of welding enables much easier control of weld parameters such as weld width and depth of penetration which can lead to a more efficient welding process.
Laser welding uses high-energy laser pulses to locally heat the material in a small area.
The energy of the laser radiation diffuses into the material through heat conduction,
and the material is melted to form a specific molten pool.
It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts,
which can realize spot welding, butt welding, stack welding, sealing welding, etc.
The welding speed is fast, no treatment is needed after welding, and the quality of the weld is high.
The weld can be precisely controlled, small focus spot, high positioning accuracy, easy to automate.
