Handheld Laser Welding Thickness & Power Table

Laser welding linear process parameters

① Adjust the swing width of the galvanometer according to the weld width of the plate
② The use of laser power is directly proportional to the thickness of the plate. The thicker the plate, the greater the laser power, and vice versa.
③ The parameters of the thin plate less than 1.0 are different. The duty cycle parameters of the laser are changed according to the degree of the thin plate. The duty cycle parameters mainly affect the penetration strength of the thin plate
④ Linetype is suitable for most welding, usually for diagonal welding and butt welding
⑤ The application range of welding gun frequency is 4-20, and the use power of different plates can be slightly adjusted
⑥ The swing width of internal angle welding galvanometer should not be too large. The smaller the moving width, the stronger the energy and the deeper the penetration

Special note:

The above parameters are only for reference. The parameter changes are mainly adjusted according to the laser power, material, welding method and width. The thinner the plate, the lower the power, and vice versa. Under normal circumstances, the laser head control parameter linetype is applicable to diagonal welding and male fillet welding, and the O-type is basically applicable to most welding.

Laser welding O-type process parameters

① Adjust the swing width of the galvanometer according to the weld width of the plate
② The use of laser power is directly proportional to the thickness of the plate. The thicker the plate, the greater the laser power, and vice versa.
③ The parameters of the thin plate less than 1.0 are different. The duty cycle parameters of the laser are changed according to the degree of the thin plate. The duty cycle parameters mainly affect the penetration strength of the thin plate
④ Linetype is suitable for most welding, usually for diagonal welding and butt welding
⑤ The application range of welding gun frequency is 4-20, and the use power of different plates can be slightly adjusted
⑥ Type O is basically applicable to all welding. The double motor swing of type O welding mode will make the material melt more thoroughly, which will be more stable than the linear welding, and the corresponding requirements for laser power are higher.
