With the improvement of technical level, the current manufacturing method has changed from traditional contact processing to laser non-contact processing to improve welding efficiency and welding effect. However, in the actual use process, various problems will still be encountered that affect the welding effect. Below, Huiyao Xiaobian will briefly explain how to deal with cracks during welding with laser welding machines and how to deal with some common faults. ​​ 一.  Cracks appear during welding by laser welding machine ​​ 1. The flow rate of the shielding gas is too large, which can be solved by reducing the flow rate of the shielding gas. ​​ 2. If the cooling speed of the workpiece is too fast, the temperature of the cooling water on the fixture should be adjusted to increase the water temperature. ​​ 3. The workpiece is not cleaned. In this case, the workpiece needs to be cleaned again. ​​ 4. If the matching gap between the workpieces is too large or there are burrs, the machining

This article will narrow the   discussion to laser welding   of tags to the terminals of a battery pack. From a welding perspective, the most important aspect of lug welding is the thickness and material of the lugs and terminals. Conductivity is the name of the game, so battery cells are usually made of aluminum or copper, sometimes plated with nickel or tin. Depending on the physical dimensions of the finished cell, the terminals can be cold rolled steel, aluminum or copper. The most common battery types are cylindrical lithium-ion cells around 18650 size (18 mm x 65 mm), large prismatic cells, and lithium polymer soft pack cells. Each battery type has different soldering requirements.     Cylindrical Batteries The key to welding cylindrical battery types is the negative terminal weld, where the cell is welded directly to the can, rather than a separate platform on the positive side. The weld on the negative terminal must not penetrate the can thickness, which is typically about 0.01

The current development of new energy can be said to be more and more perfect, and its application in all walks of life is also very extensive. New energy batteries are mainly assembled and produced through the new energy battery assembly line. Below, the editor of Huiyao will give you a detailed introduction to the advantages of the new energy battery assembly line.   1. Components of the new energy battery assembly line Roller production line, plate chain production line, double-speed chain production line, drying channel assembly line, spraying assembly line, suspension chain assembly line, belt assembly line, plug-in assembly line, aging assembly line, logistics transportation assembly line, non-standard supporting assembly line, manipulator, workbench, turning machine, etc. Automatic assembly line equipment and related accessories.   2.
