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

Special Note:
Please note that the above parameters are just guidelines. Actual adjustments to 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 line type parameter for laser head control is typically suitable for diagonal and male fillet welding, while the O type is suitable for most welding applications.
Type O process parameters of laser welding
① Adjust the turning width of the galvanometer to match the width of the plate being welded.
② The required laser power is directly proportional to the thickness of the plate. The thicker the plate, the greater the laser power required and vice versa.
③ The parameters for thin sheets less than 1.0mm are different and should be adjusted based on the thickness of the thin sheet. These parameters mainly affect the penetration resistance of the thin plate.
④ The line type is suitable for most types of welding, including diagonal and butt welding.
⑤ The frequency range of the welding gun is 4 to 20 Hz, and the power used for different plates can be adjusted as needed.
⑥ Type O is suitable for all welding applications. The double oscillation of the motor in O-type welding mode ensures that the material is completely melted, resulting in more stable welding compared to linear welding. Higher laser power is required for this mode.
