Laser welding is a new type of welding method. It is mainly aimed at welding thin-walled materials and precision parts. It can realize spot welding, butt welding, overlap welding, sealing welding, tailor welding, penetration welding, filler welding, seam welding and airtight welding. Flexible seam welding, and can adapt to a variety of welding tracks. High aspect ratio, small weld width, small heat-affected zone, small deformation, fast welding speed, smooth and beautiful weld, no need or simple treatment after welding, high weld quality, no air holes, and precise control, The focused light spot is small, the positioning accuracy is high, and it is easy to realize automation.
Advantages of laser welding:
Compared with other welding methods, its advantages are: small solder joints; small heat-affected zone, thin-walled metal does not deform, fast welding speed, high positioning accuracy; self-fusion welding does not require welding wire, high welding seam strength, no pollution, no perforation and firm Beautiful. Laser welding of electronic components will not damage the sealing ring and IC microcircuit; it can improve the appearance and performance stability of the product, and enhance the competitiveness of the product!
In short, laser welding has high production efficiency, stable and reliable processing quality, and good economic benefits and benefits. In an era where new equipment, new materials, new technologies and new processes are constantly emerging and constantly updated, producers must not only understand the characteristics, advantages and requirements of laser welding, but also recognize many innovations and future trends in this field. Only in this way can they grasp The trend of technology can always be at the forefront of the times.
Laser welding application range:
Electronics industry: sensor and transformer packaging and welding, filter, power module sealing welding; mobile phone battery, power battery shell sealing, solid state relay sealing and breaking welding, connector welding, mobile phone, MP3 and other metal shells and structural parts welding. Welding of motor shell and connection, optical fiber connector joint, etc.
