Precautions for Laser Welding Aluminum Alloy Windows

Because aluminum alloy is a non-ferrous metal with strong reflectivity to various types of light, laser, being an even more intense beam of light, can cause even more pronounced reflections on its surface. Aluminum alloy also possesses high thermal conductivity. Therefore, when aluminum alloys laser welding, it is crucial to swiftly increase the power density of the laser to prevent reflection or conduction.

Aluminum materials have characteristics of high thermal conductivity and reflectivity. Thus, welding parameters must be chosen according to the specific type and thickness of the aluminum material. Selecting appropriate power, focal length, and focus diameter parameters allows for control of the heat input and the formation of the molten pool during welding, ensuring the desired weld appearance and quality.

Attention must be paid to factors such as beam quality and gas shielding to guarantee welding quality and stability.

1. Pre-weld cleaning: Before welding, it is essential to thoroughly remove any oxidation, rust, and oil residues from the welding joint and wire surface of aluminum alloy doors and windows. This can be achieved through chemical, mechanical, or laser cleaning.

2. Backing plate: Due to the low strength of aluminum alloy at high temperatures, the welded joint metal is prone to collapse during welding. Backing plates are used to support the molten pool and nearby metal, preventing collapse.

3. Alignment: Precise positioning and clamping of door and window components is necessary to ensure they do not move during the welding.

4. Pre-heating: When welding aluminum alloy doors and windows with a thickness typically ranging from 10mm to 15mm, pre-weld heating is required. Different types of aluminum alloys have varying melting points and thermal conductivities, so pre-heating temperatures usually fall between 100°C to 200°C.

5. Post-welding steps: Allow for a cooling period to reduce heat stress.

  • Weld seam cleaning: Remove any remaining welding slag and oxides from the weld seam and its surrounding area.
  • Passivation treatment: To enhance the corrosion resistance of aluminum alloy doors and windows, consider surface treatment or coatings on the weld seams.
