Protective glass of the laser welding machine

Protective Glass for Laser Welding Machines

Fiber laser machines come in two types: handheld laser welding, automatic laser welding, and laser cutting, each of which has different protective glasses or laser protective lenses.

Laser Welding

Function: Laser welding focuses high energy on a single point, melting the materials and creating a strong bond between the parts. This method is ideal for welding heat-sensitive materials and for precise industrial applications.

Applications:

• Joining body components of vehicles and batteries of electric cars.
• Welding medical instruments made of stainless steel or titanium.
• Welding sensitive parts in jet engines and satellites.

Features: The working environment of laser welding machines typically involves high temperatures and thermal stress. Therefore, the protective glass must have high resistance to heat and material splashes.

Laser Cutting

Function: Laser cutting uses a laser beam to separate or shape materials. This process is performed with high precision and is ideal for producing complex and delicate parts.

Applications:

• Cutting metals and glass for building facades.
• Precise designs in crafts and advertising.
• Manufacturing small and precise electronic components.

Features: The protective glass in laser cutting machines is primarily used to reduce beam dispersion and protect the lenses from contamination, as the risk of material splashes in this process is lower.

Laser Lens Protector

The laser lens protector is a tool or cover used to protect the lenses of the laser machine from scratches, liquid droplets, dust, and contaminants. Its main purpose is to prevent damage to the focusing and collimating lenses in the laser device. The clarity and optical properties of the laser lens protector are crucial for laser welding, as any disturbance can affect the quality of the weld.

The lens protector of the laser head, or the protective glass of automatic and handheld laser welding machines and laser cutting machines, plays a vital role in operator safety, maintaining device performance, and improving operation quality. Selecting the right laser lens protector based on the type of application, laser wavelength, and machine power, along with proper maintenance, contributes to increasing efficiency and extending the device’s lifespan. Laser welding, emphasizing the strong bonding of materials, and laser cutting, aiming for precise separation, each require laser lens protectors with different characteristics, optimized for specific applications.

Laser Head Protector

Role and Function of the Laser Head Protector in Laser Devices

Role of the Laser Head Protector

The laser head protector, as one of the key components of laser devices, has important responsibilities:

1. Operator Safety: Protecting the eyes and skin from harmful radiation and scattered beams.
2. Equipment Protection: Preventing contamination, scratching, or damage to the lenses and sensitive components of the device.
3. Maintaining Operation Quality: Reducing beam divergence and preserving clarity in the path of the laser.

Features:

• High resistance to heat and impact.
• Clarity for allowing the laser beam to pass without quality degradation.
• Durability against scratches and wear.
• Filtering harmful wavelengths to protect the operator.

Types of Protective Glasses and Their Applications

Coated Glass: These glasses are designed with special coatings that absorb or reflect harmful wavelengths.

Features:

• Reflect or absorb harmful rays.
• Reduce heat transferred to the glass.
• Increase the accuracy and quality of operations.

Applications: High-power welding and cutting machines, such as in the automotive and aerospace industries.

Ceramic Glass: Ceramic glasses are suitable for harsh working conditions due to their high thermal and mechanical resistance.

Features:

• Stability at high temperatures and mechanical impacts.
• Long-term optical clarity.

Applications: Welding parts in jet engines or cutting materials at high temperatures.

Laser-Resistant Polycarbonate: This lightweight and flexible polymer material is designed for portable devices.

Features:

• Impact absorption and prevention of cracking.
• Low weight for ease of handling.

Applications: Smaller, lower-power devices, such as in medical applications and crafts.

Multi-Layer Glass: These glasses consist of various layers and provide multifunctional performance.

Features:

• Safety against breakage.
• Reduced heat transfer.
• Multiple filtering for different wavelengths.

Applications: Safety-sensitive environments and multifunctional devices.

Materials Used in Protective Glasses

• Ceramic Glasses: Made from heat-resistant materials such as aluminum silicates, they can withstand working temperatures up to 1000 degrees Celsius.
• Laser-Resistant Polycarbonate: Made from lightweight polymers with heat and impact-resistant additives. These materials have good clarity but are limited in high-power applications.
• Multi-Layer Glasses: Include different layers such as silicon or metal fluorides, providing multiple filtering capabilities and high safety.
