When selecting lasers for stainless steel welding, consider material thickness, beam quality, pulse duration, and other factors like power stability and maintenance costs. For thin stainless steel (less than 3 mm), fiber lasers and diode lasers are ideal due to their high beam quality and precision. For medium to thick stainless steel, high-power continuous fiber lasers are preferred for deeper penetration. Matching equipment is also essential. Pulsed laser welding machines are suitable for small, high-precision tasks, while continuous laser welding machines and laser welding robots are ideal for larger components and automated production. Auxiliary equipment, such as optical microscopes and shielding gas systems, ensures weld quality and prevents oxidation. Proper selection and matching of lasers and equipment enhance welding accuracy, efficiency, and durability.

Laser welding of aluminum alloys is a complex process due to the material’s high reflectivity and thermal conductivity. These properties can lead to significant energy loss and increased welding costs. To address these challenges, high-power lasers and surface pre-treatment methods, such as sandblasting or chemical cleaning, are used to reduce reflectivity. Additionally, optimizing welding parameters like laser power, welding speed, and defocus amount is crucial for minimizing porosity and ensuring high weld quality. Using high-purity argon as a shielding gas helps prevent oxidation and porosity formation. Selecting appropriate equipment, such as fiber laser welding machines and laser welding robots, further enhances efficiency and quality. These machines offer high energy density, good beam quality, and automation capabilities, making them suitable for both thin and thick aluminum sheets. Auxiliary equipment, including optical microscopes and ultrasonic testing instruments, ensures weld quality. By carefully managing these factors, laser welding can achieve high-quality, durable, and efficient welds, making it a preferred method in industries like automotive, aerospace, and electronics.

Vacuum glass laser welding is a high-precision technique offering numerous advantages. It ensures strong, crack-free welds with minimal impact on glass transparency, making it ideal for applications requiring optical clarity. The non-contact, localized heating process prevents mechanical damage and material deformation, while fast welding speeds boost production efficiency. Suitable for various environments, including vacuum, it prevents oxidation and contamination. The equipment, including high-power lasers, precision motion platforms, and vacuum systems, supports complex shape welding and automation. This technology is widely used in construction, transportation, and electronics for its ability to create high-quality, durable glass joints.
