lithiumBattery Tab<\/a>Welding is mainly divided into single-point and multi-point welding, which is used for lithium battery tabs, lithium battery positive and negative electrodes, battery aluminum foil and aluminum plate, battery copper foil and copper plate, battery nickel plate and nickel mesh, etc. Copper foil is about 0.08mm, aluminum foil is about 0.01mm, and nickel and aluminum sheets are about 0.1mm.<\/p>\n

Laser equipment lithium battery ear welding machine is applicable to single-point, multi-point, single-layer, multi-layer, square, strip, and single-piece welding processes of copper plates, aluminum plates, nickel plates, nickel strips, copper foils, aluminum strips, aluminum foils, aluminum covers, aluminum shells, aluminum-nickel composite strips and other materials.<\/p>\n

\u00a0Laser welding principle<\/strong><\/p>\n

Laser welding utilizes the excellent directionality and high power density of the laser beam to focus the laser beam into a very small area through an optical system. In a very short time, a highly concentrated heat source area is formed in the welding area, which melts the welded materials and forms a strong welding point and weld.<\/p>\n

\"\"

There are 2 types of laser welding<\/strong><\/p>\n

Heat conduction welding and deep penetration welding<\/p>\n

The laser power density of laser heat conduction welding is 105 to 106 w\/cm2, and the laser power density of laser deep penetration welding is 105 to 106 w\/cm2<\/p>\n

Penetration welding and seam welding<\/p>\n

Penetration welding does not require drilling of the joint, and the processing is relatively simple. Penetration welding requires a higher power laser welding machine. The fusion depth of penetration welding is lower than that of seam welding, and the reliability is relatively poor.<\/p>\n

Seam welding requires a laser welding machine with lower power than penetration welding. Seam welding has a higher penetration depth than penetration welding and is relatively more reliable. However, the connection part needs to be punched, which is relatively difficult to process.<\/p>","protected":false},"excerpt":{"rendered":"
