Laser welding machines are suitable for a variety of materials, including metal materials such as stainless steel, carbon steel, aluminum alloy, copper, titanium alloy, as well as some plastics and composite materials.

Laser welding melts the surface of the material through a high-energy laser beam, and then forms a strong weld joint during the cooling process. The high energy density and precise control of the laser beam enable it to achieve high-quality welding.

– High precision: capable of fine and complex welding.

– High speed: fast welding speed and improved production efficiency.

– High quality: smooth welds, high welding strength and small deformation.

– Automation: easy to integrate with robots and automation systems.

– Non-contact: reduce mechanical stress and heat-affected zone of materials.

Although laser welding machines have many advantages, they also have some disadvantages, mainly including:

1. **High equipment cost**
Laser welding machines and their supporting equipment are expensive, especially high-power lasers, and the initial investment is large.

2. **Complex maintenance**
Lasers and optical systems require regular maintenance and calibration, which has high maintenance costs and strict technical requirements.

3. **Material restrictions**
The welding effect of highly reflective materials (such as copper, aluminum, etc.) is poor, and special measures need to be taken.

4. **High precision requirements**
High requirements for workpiece assembly precision, and slight deviations may cause welding defects.

5. **Thickness restrictions**
The welding thickness is limited, especially single-pass welding, and thick plate welding requires multiple operations or higher power equipment.

6. **Safety risks**
Laser radiation is harmful to the eyes and skin, and strict safety protection measures are required.

7. **Heat-affected zone**
Although the heat-affected zone is small, it may still affect material properties in precision welding.

8. **Environmental requirements**
High requirements for the working environment, dust, vibration, etc. may affect the welding quality.

9. **High energy consumption**
High-power lasers consume a lot of energy and have high operating costs.

10. **High technical threshold**
Operation and maintenance require professional technicians, which increases labor costs.

In summary, laser welding machines have certain limitations in terms of cost, maintenance, material adaptability, accuracy, thickness, safety, environmental impact, energy consumption and technical requirements.

The power selection of the laser welding machine depends on the type, thickness and welding speed of the welding material. Generally speaking, thick materials and high welding speeds require higher laser power.

– Lens cleaning: Clean the laser and focusing lens regularly to ensure beam quality.

– Cooling system maintenance: Check the coolant level and keep the cooling system running normally.

– Gas supply: Ensure that the shielding gas (such as nitrogen, argon) is in sufficient supply and of high purity.

– Software update: Keep the latest version of the control software to improve performance and safety.

The laser welding machine is designed with a variety of safety measures, such as protective covers, laser shields and emergency stop buttons. However, appropriate personal protective equipment such as protective glasses and gloves must still be worn during operation.

CQX Laser will provide operation training through online guidance (including installation & operation videos, manuals, etc.) or offline teaching to ensure that customers can use the equipment correctly. In addition, technicians can obtain more in-depth knowledge and skills through professional training institutions.

Laser welding is widely used in automobile manufacturing, aerospace, medical equipment, electronic components, jewelry processing and precision instruments.

The service life of a laser welding machine is usually more than 10 years, but the specific life depends on the frequency of use, maintenance status and equipment quality.
