MOPA fiber lasers have excellent applications in industrial marking and engraving. Not only that, it has a wide pulse width range, high peak power, high frequency, and excellent beam quality, which can meet the needs of high-quality industrial processing. Ultra-thin dissimilar metal materials also have excellent performance in welding, mainly used in 3C electronics, new energy and other fields.
Welding of dissimilar metal materials
Note: The horizontal material is the base material, and the vertical material is the welding material.
Welding process guidance:
1. Welding laser: MOPA70-200, the thicker the metal material, the higher the material reflectivity, the higher the laser power required;
2. Welding method: according to the shape of the welding area, you can choose spiral spot welding and jitter line welding;
3. Welding configuration: galvanometer scanning welding. Due to the high welding laser power, it is recommended to use a fused quartz or composite material focusing field lens to prevent welding instability caused by thermal lens problems;
4. Welding parameters: small and medium pulse width, high frequency, medium and low speed, can be welded firmly, and the welding surface is smooth.
Mobile phone/computer industry
Laser welding can greatly improve the production level and quality of internal components of electronic products. Laser welding is used in many places in mobile phones, such as mobile phone mid-plate shrapnel, antenna shrapnel, camera module shrapnel welding, etc. Laser welding is used to weld metal shrapnel To the conductive position, it can effectively prevent oxidation and corrosion on the basis of not affecting the conductivity. The shrapnel material is generally copper nickel plating, aluminum gold plating, steel copper plating, steel gold plating, etc. The mobile phone shell material is generally aluminum or aluminum magnesium alloy .
The MAX MOPA laser is used to weld the shrapnel of the mobile phone, the welding point is beautiful, and the welding firmness is stronger.

Battery industry
The new energy industry has developed rapidly in recent years. Lithium battery and power battery connection pieces can be well applied to pulse laser welding. MOPA laser is used to weld metal connection pieces with different properties to the battery electrodes to make them perfectly combined. It does not affect conductivity. The material of the connection piece is generally aluminum, nickel, nickel-plated copper, etc. The battery electrode material is mostly aluminum or copper.
The MAX MOPA laser is used to weld the battery connection piece. The heat-affected zone of the welding spot is small and beautiful. The welding penetration is deeper than that of the traditional laser.
