Laser welding linear process parameters
① Adjust the swing width of the galvanometer to match the width of the plate being welded.
② The laser power required is directly proportional to the thickness of the plate. The thicker the plate, the higher the laser power needed, and vice versa.
③ The parameters for thin plates less than 1.0mm are different. The duty cycle parameters of the laser must be adjusted based on the thickness of the thin plate. These parameters mainly impact the penetration strength of the thin plate.
④ The linetype is suitable for most welding types, including diagonal and butt welding.
⑤ The range of frequency for the welding gun is 4-20Hz, and the power used for different plates can be adjusted as needed.
⑥ The swing width of the galvanometer for internal angle welding should not be too large. The smaller the swing width, the higher the energy and the deeper the penetration.

Special note:
Please note that the above parameters are only guidelines. The actual adjustments to the parameters should be based on factors such as laser power, material, welding method, and width. Generally speaking, the thinner the plate, the lower the laser power required, and vice versa.
The linetype parameter for laser head control is typically suitable for diagonal and male fillet welding, while the O-type is suitable for most welding applications.
Laser welding O-type process parameters
① Adjust the swing width of the galvanometer to match the width of the plate being welded.
② The laser power required is directly proportional to the thickness of the plate. The thicker the plate, the higher the laser power needed, and vice versa.
③ The parameters for thin plates less than 1.0mm are different and must be adjusted based on the thickness of the thin plate. These parameters primarily affect the penetration strength of the thin plate.
④ The linetype is suitable for most welding types, including diagonal and butt welding.
⑤ The range of frequency for the welding gun is 4-20Hz, and the power used for different plates can be adjusted as needed.
⑥ The O-type is suitable for all welding applications. The double motor swing in O-type welding mode ensures that the material is melted thoroughly, resulting in a more stable weld compared to linear welding. Higher laser power is required for this mode.
