In the selection of laser welding machine, technical parameters are very important considerations. The following details some common technical parameters and explains how to compare them.
1. Laser power (W) : The laser power of the laser welding machine is a key indicator of its welding ability. Higher power usually means higher welding speed and wider welding range. Choosing the right power depends on the desired welding depth and speed. Lower power is suitable for thin materials or fine welding, while higher power is suitable for thick materials or large size welding.
2. Wavelength (nm) : The wavelength of the laser welding machine determines its applicability to different materials. In general, the shorter wavelength is suitable for the welding of metal materials, while the longer wavelength is suitable for the welding of non-metallic materials. Choosing the right wavelength ensures high welding quality and efficiency.
3. Spot diameter (mm) : spot diameter determines the size of the welding area. The smaller spot diameter is suitable for fine or precision welding, while the larger spot diameter is suitable for large-size welding. Selecting the right spot diameter can improve the welding quality and accuracy.
4. Repetition frequency (Hz) : Repetition frequency refers to the number of pulses emitted by the laser welding machine per second. Higher repetition rates can improve welding speed and efficiency. However, in some special applications, a lower repetition rate may be more suitable because it can reduce thermal effects and deformation.
5. Weld width (mm) : The weld width is the width of the metal fusion area generated during the welding process. Smaller weld widths can improve weld quality and appearance. Choosing the appropriate weld width depends on the desired weld strength and appearance requirements.
6. Control system: An advanced control system can provide more welding parameter adjustment and monitoring functions to meet different welding requirements. Some control systems also have data logging and storage capabilities that can be used for quality control and traceability.
7. Cooling system: Laser welding machine needs an effective cooling system to maintain the operating temperature of the equipment and protect the laser. Choosing a welding machine with an efficient cooling system can improve the stability and life of the equipment.
8. Safety characteristics: Considering the particularity of laser radiation and optical components, it is essential to choose a welding machine with good safety characteristics. This may include light shielding, safety switches, alarm systems, etc.
When comparing these technical parameters, you must first understand your welding needs and budget. Secondly, according to the demand to determine the required power, wavelength, spot diameter and other parameters. By viewing the technical specification table of different brands and models of laser welding machines, make a detailed comparison and find the welding machine that best suits your needs. At the same time, you can refer to the evaluation and recommendations of other users and choose reliable brands and dealers to ensure the purchase of high-quality laser welding machines.
