Laser welding profile rolling forming machine is used to make the metal profile with close seaming by laser welding and then make it more stronger and closed. Laser welding is the use of high-energy laser pulses to locally heat a material in a small area. The energy radiated by the laser is directed through heat transfer to the internal diffusion of the material, melting the material and forming 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 achieve spot welding, butt welding, overlap welding, seal welding, etc., with high aspect ratio, small weld width, small heat affected zone, small deformation, fast welding speed, smooth and beautiful welds, no need for treatment or simple treatment after welding, high weld quality, no air holes, precise control, small focus points, high positioning accuracy, and easy to achieve automation.
Compared with TIG welding and HF welding, laser welding belong to the MIDDLE, as the cost is not so high but the speed is not so slow. Let us take a random profile for example to show you how it works.

Laser welding operation manual like this:
Step 1: How to put the the welding machine in the right position.
Step 2: power adjustment:
Laser light output mode:
First, continuous mode, do not check pulse light output
Second, pulse marking line segment mode, check pulse light output
Adjust the laser power. Adjust the stable power according to the welding conditions,
as shown by the red arrow in the figure
The modulation frequency is set to 20000 and the duty cycle is set to 100
When using together with the rolling forming machines, if you feel that the HF welding is too much complicated and cost higher and then you can try to choose the laser welding. It can do the online welding smoothly. For more information, please contact us at any time.
