As a Laser Welding Machine Factory, share it with you. It is indispensable for the lithium ion battery electric welding machine to prepare for cleaning before welding. Foreign objects often appear at the upper and lower electrodes. The power-on inspection is necessary when we use the spot welding machine. This is the point of use. An important part of the welding machine, sometimes electrical equipment may show electricity, of course, our gas circuit system may also have electricity leakage, so we must check before using lithium-ion batteries to ensure the safety of our production get on.
Lithium Battery Laser Welding Machine
How many welding methods are there for lithium-ion batteries?
① Wave welding: essentially a combination of ultrasonic welding and laser welding;
②Ultrasonic welding: The advantage of this method is that the welding is simple, but it takes up more space, and the volume and grouping efficiency of the module will be lower;
③Laser welding: At present, this method is the most widely used, but the structure is slightly different;
④ Laser welding of dissimilar metals: This welding method is also very efficient in grouping, and the production speed is fast.
Application of laser welding in the lithium-ion battery industry
Laser welding uses a laser beam as an energy source, and uses a focusing device to focus the laser beam into a high-power-density beam to irradiate the surface of the workpiece for heating. Under the use of heat conduction of metal materials, the inside of the material melts to form a specific molten pool. When using laser welding, the heat-affected zone of the workpiece is small; the solder joints are small, and the welding dimensional accuracy is high; the welding method is non-contact welding, no external force is required, and the product deformation is small; the welding quality is high; the efficiency is high, and it is easy to realize automatic production .
The shell materials of power lithium batteries are aluminum alloy and stainless steel, of which aluminum alloy is the most used, generally 3003 aluminum alloy, and a few use pure aluminum. Stainless steel is the material with the best laser weldability, especially 304 stainless steel. Whether it is pulsed or continuous laser, welds with good appearance and performance can be obtained.
