1. Insulated cup
A thermos cup is a commonly used household item, который незаменим как дома, так и в дороге. Пряжка, нижний, and even the circumference of the inner liner of stainless steel vacuum insulated cups need to be seamlessly welded. Laser welding can not only ensure the overall welding effect, but most importantly, it can achieve automated welding management, ensuring the exquisite and efficient welding seams. Stainless steel insulated cups are ubiquitous in daily life, but how are high-end stainless steel insulated cups welded during production and processing?
The stainless steel insulated cup is made of inner and outer double-layer stainless steel. The inner and outer shells are combined together by welding technology, and the air in the interlayer between the inner and outer shells is extracted by vacuum technology to achieve vacuum insulation effect. Only in this way can residents have a good user experience.
2. Under normal circumstances
The thinner the cup material, the longer the insulation time, but the welding interface is not firm and the cup body is prone to damage and deformation, which affects its service life; So it is recommended to wrap the outer layer of the inner liner with metal film and copper plating, which have a similar thickness and are not easily damaged at the welding interface, for splicing, in order to achieve a dense and strong welding interface, and achieve precise sealing.
Although traditional welding methods and processes have shown good results, they also have many shortcomings. Especially for welding in many small areas, it is impossible to achieve perfection. Taking the welding of stainless steel vacuum insulated cups as an example, the traditional welding method has some shortcomings in terms of its effectiveness. Однако, laser welding can make up for its shortcomings by achieving clever continuous welding and pulse welding, and adopting non-contact welding methods for difficult to weld parts.
Traditional argon arc welding is a welding technique based on the principle of ordinary arc welding, which uses argon gas to protect the metal welding material, melts the welding material into a liquid state on the welded substrate through high current to form a molten pool, and achieves metallurgical bonding between the welded metal and the welding material. This method of welding stainless steel insulated cups has a large and unsightly weld seam, and the welded product has a very obvious protrusion line at the cup mouth, which can easily cause product deformation.
Due to the strict requirements for welding and sealing of insulated cups, the traditional argon arc welding method is not suitable for welding stainless steel insulated cups, so we have to mention our laser welding machine.
Stainless steel insulated cup laser welding machine is a type of laser welding equipment that couples high-energy laser beams into optical fibers, transmits them over long distances, collimates them into parallel light through a collimating mirror, and focuses them on the workpiece for welding. It belongs to non-contact welding and does not require pressure on the product during the operation process, so it will not cause deformation to the product.
3. QCW laser welding machine
The QCW laser welding machine can achieve time and energy splitting, and can process multiple beams simultaneously. It can perform flexible transmission non-contact welding on parts that are difficult to access for welding, providing greater flexibility and conditions for more precise welding.
The material of stainless steel insulated cups is mainly stainless steel 304, and welding production requires strict safety control. Laser welding meets this requirement well and is easy to operate. Traditional welding methods are time-consuming and labor-intensive for welding difficult parts. Однако, laser welding can improve efficiency and ensure quality reliability during the production process. Relatively speaking, this welding method can better reduce costs and increase profits for enterprises.The biggest advantage of using laser welding is high efficiency, exquisite welds, environmental friendliness, strong controllability in production, and very low defect rate.
