What you need to know about buying a laser welding machine
Knowledge to Know When Purchasing a Laser Welding Machine
When purchasing a laser welding machine, you need to understand the following aspects of knowledge:
I. Laser Welding Principle
Laser welding is a welding method that uses a high-energy-density laser beam as a heat source to locally heat the material to a molten state and then cool and solidify to form a weld seam. Laser welding has the advantages of fast welding speed, high weld quality, small heat-affected zone, and small deformation. Understanding the principle of laser welding can help you better understand the working process and performance characteristics of the laser welding machine.
II. Types of Laser Welding Machines
According to laser types:
Solid-state laser: Such as Nd:YAG laser, which has the advantages of good stability and high beam quality, but relatively low power.
Fiber laser: It has the advantages of high power, high efficiency, and good beam quality, and is currently the most widely used laser type.
Carbon dioxide laser: Suitable for welding non-metallic materials such as plastics and wood.
According to welding methods:
Pulse laser welding: Suitable for welding thin plate materials. It has a fast welding speed and a small heat-affected zone.
Continuous laser welding: Suitable for welding thick plate materials. It has high welding efficiency and good weld quality.
III. Performance Parameters of Laser Welding Machines
Power: The power of a laser welding machine determines its welding capacity. Generally speaking, the higher the power, the faster the welding speed, and the greater the thickness of the material that can be welded.
Wavelength: Different types of lasers have different wavelengths. The wavelength will affect the penetration ability and welding effect of the laser.
Beam quality: The better the beam quality, the stronger the focusing ability of the laser, and the higher the welding precision.
Welding speed: The welding speed is the length welded per unit time. The faster the welding speed, the higher the production efficiency.
Repeatability precision: Repeatability precision refers to the precision of the laser welding machine when welding the same position multiple times. The higher the repeatability precision, the more stable the welding quality.
IV. Applicable Materials
Different types of laser welding machines are suitable for different materials. Before purchasing a laser welding machine, you need to understand the type of material you want to weld and the welding effect of the laser welding machine on this material. For example, fiber lasers are suitable for welding most metal materials, while carbon dioxide lasers are suitable for welding non-metallic materials.
V. Equipment Quality and Reliability
Brand and manufacturer: Choosing a well-known brand and a powerful manufacturer can ensure the quality of the equipment and after-sales service.
Equipment structure: The structure of the laser welding machine should be stable and reliable, with good heat dissipation performance and protection performance.
Key components: Understand the quality and performance of key components of the laser welding machine, such as lasers, optical systems, and control systems. The quality of these components directly affects the overall performance and reliability of the equipment.
VI. After-sales Service
Training and technical support: The manufacturer should provide operation training and technical support for the equipment to ensure that users can use the equipment correctly.
Maintenance and repair: Understand the manufacturer's maintenance and repair services, including repair response time and repair costs.
Spare parts supply: Ensure that the manufacturer can provide spare parts supply for the equipment in a timely manner to ensure the normal operation of the equipment.
VII. Price and Cost Performance
The price of laser welding machines varies depending on factors such as brand, power, and performance. When purchasing a laser welding machine, don't just look at the price. You also need to consider factors such as the performance and quality of the equipment, as well as after-sales service, and choose equipment with high cost performance.
In conclusion, when purchasing a laser welding machine, you need to understand knowledge in aspects such as the principle of laser welding, types, performance parameters, applicable materials, equipment quality and reliability, after-sales service, and price and cost performance. Only by fully understanding this knowledge can you choose a laser welding machine that meets your needs.
