YAG laser welding machine is a machine that uses high-energy pulsed laser to weld workpieces. The China YAG laser welder machine focuses the laser beam on the surface of the workpiece through a specific laser generation and transmission system, causing the workpiece to partially melt and achieve welding.
Working Principle
• The laser power supply first pre-ignites the pulse xenon lamp, and discharges the pulse xenon lamp through the laser power supply, so that the xenon lamp generates light waves with a certain frequency and pulse width.
• The light wave irradiates the ND:YAG laser crystal through the focusing cavity, thereby exciting the ND: YAG laser crystal to generate laser.
• The laser then passes through the resonant cavity to generate a pulse laser with a wavelength of 1064nm.
• The laser is expanded, reflected (or transmitted through optical fiber), and focused, and then radiated to the surface of the workpiece, so that the workpiece is partially melted to achieve welding.
Advantages
1. High precision: Due to the small focused spot and high positioning accuracy, precise welding control can be achieved.
2. High efficiency: fast welding speed, small heat-affected zone, small deformation, and improved production efficiency.
3. High quality: the weld is flat, beautiful, without pores, and the weld quality is high.
4. Flexibility: It can be applied to the welding of a variety of materials, such as titanium, aluminum, copper, zinc, gold, silver and other metals and alloys.
5. Non-contact welding: There is no physical contact between the workpiece and no force is applied to the workpiece, which reduces the deformation and damage of the workpiece.
6. Easy to automate: The welding process can be controlled by PLC or industrial PC, which is easy to automate production.
Application
YAG laser welding machines are widely used in many fields, including but not limited to:
1. Automobile manufacturing industry: used for welding of automobile parts such as engine cylinder gaskets, hydraulic tappet seal welding, filter seal welding, spark plug welding, valve push rod welding, etc.
2. Electronic industry: used for welding of mobile phone batteries, power battery shell seal welding, solid-state relay seal welding, connector data cable welding and other electronic products.
3. Hardware industry: used for welding of hardware products such as tools, accessories, tableware, lighting fixtures, etc.
4. Other industries: also widely used in aerospace, medical equipment, jewelry and other fields.
Development Trends
With the continuous advancement of laser technology and the continuous expansion of application fields, YAG laser welding machines will continue to play an important role in the future. At the same time, with the development of intelligent manufacturing and industrial Internet, YAG laser welding machines will be more intelligent, automated and integrated, bringing greater benefits and value to the production and management of enterprises.
