When stainless steel and aluminum alloy are welded simultaneously, parameter switching is relatively complex, mainly due to the following reasons:
Differences in material properties: The physical properties such as thermal conductivity and melting point of stainless steel and aluminum alloy are different, resulting in the need to adjust welding parameters (such as power, speed, and shielding gas) separately.
Laser absorption rate: Aluminum alloy has a lower absorption rate for laser, usually requiring higher power or specific wavelengths; Stainless steel is relatively easy to absorb laser, with different parameter requirements.
Protective gas: Argon or helium gas is commonly used for aluminum alloy welding, while argon or mixed gas is more commonly used for stainless steel, which may require switching or adjusting the gas type.
Do we need to replace the laser？
The same laser: If the laser has a wide parameter adjustment range, it may not need to be replaced, but the parameters need to be adjusted frequently.
Different lasers: If there is a significant difference in welding requirements between two materials, different lasers may need to be used, such as fiber lasers suitable for stainless steel, while aluminum alloys may require higher power or specific wavelength lasers.
Summary: Parameter switching is quite complicated, and whether to replace the laser depends on the performance of the laser and welding requirements.
