Laser welding is a precise and efficient technique used in various industries for joining metals. Different metals require different laser parameters to achieve optimal weld quality. This blog will guide you through setting the parameters for welding stainless steel (SS), mild steel (MS), aluminum, and brass using a Spectrum Laser Inc. machine. We will also discuss the power requirements for each type of metal.
#Understanding the Basics
Before diving into specific parameters, it’s essential to understand the key factors that influence laser welding:
1.Laser Power: The energy output of the laser, measured in watts (W).
2.Welding Speed: The speed at which the laser moves along the weld joint.
3.Focal Position: The position of the laser focal point relative to the surface of the material.
4.Shielding Gas: Used to protect the weld pool from oxidation and contamination.
1. Stainless Steel (SS)
Stainless steel is known for its corrosion resistance and strength. However, it requires precise control of laser parameters due to its thermal properties.
#Recommended Parameters:
- Laser Power: 1000W - 2000W
- Welding Speed: 20-50 mm/s
- Focal Position: 0 to -1 mm below the surface
- Shielding Gas: Argon or Helium
2. Mild Steel (MS)
Mild steel is widely used due to its malleability and ductility. It is relatively easier to weld compared to other metals.
Recommended Parameters:
- Laser Power: 500W - 1500W
- Welding Speed: 30-70 mm/s
- Focal Position: 0 to -1 mm below the surface
- Shielding Gas: Argon, CO2, or a mix
3. Aluminum
Aluminum is lightweight and has a high thermal conductivity, requiring higher laser power and specific techniques to manage heat dissipation.
Recommended Parameters:
- Laser Power: 2000W - 4000W
- Welding Speed: 20-40 mm/s
- Focal Position: -0.5 to -1.5 mm below the surface
- Shielding Gas: Argon
4. Brass
Brass, an alloy of copper and zinc, has high thermal conductivity and reflectivity, making it a bit challenging to weld.
Recommended Parameters:
- Laser Power: 1500W - 2500W
- Welding Speed: 10-30 mm/s
- Focal Position: 0 to -1 mm below the surface
- Shielding Gas: Argon or Nitrogen
