Thermos cup is a common household product, which is indispensable for students, office workers and travelers, especially in cold winter. The thermos cup is a vacuum bottle made of stainless steel. The bottom and inner container of the cup need to be welded seamlessly. Using three-dimensional laser welding equipment can not only realize automatic welding processing, but also improve the welding effect and work efficiency.

How does the stainless steel thermos cup we use complete the welding process? The thermos cup is generally composed of inner and outer double-layer stainless steel. The inner container is combined with the shell through welding technology, and the interlayer air in the combination is extracted through vacuum technology, so as to achieve the effect of vacuum heat insulation. This technology can make people rely on the thermos cup and get a better sense of use.

The thinner the cup material, the longer the holding time. During the welding process of thin plate materials, the joint is not firm, the melting point temperature is too high, and the cup is easy to deform and damage, which will affect the service life and sense of use of the thermos cup. Therefore, most manufacturers use metal film splicing in the lining, which is small in thickness, convenient for welding and not easy to be damaged. Use metal film splicing to realize the strength of the joint and the sealing of the butt joint.

The premise of steady development lies in whether we can make continuous innovation and progress, as is the case with 3D laser welding technology. Although other welding processes have achieved good results, there are still some deficiencies in some aspects. For the welding process of stainless steel thermos cup, although using other processes will have some shortcomings, these shortcomings can be made up by using laser welding process, ingeniously using non-contact method to realize continuous welding. Laser welding will heat the surface by laser radiation, and the surface of the workpiece will be guided by heat transfer to internal diffusion, so as to complete the welding process.

Laser welding can process multiple beams while decomposing light. Flexible machining on the surface close to the workpiece has flexibility in the machining process, which provides convenient conditions for the welding process. Stainless steel thermos cup is mainly made of stainless steel 304, which not only ensures safe production, but also has high requirements for products. Laser welding can well meet this requirement, and it is simple to operate and easy to use. Other welding methods will be time-consuming, labor-consuming and consumables in parts that are difficult to weld. However, laser welding technology can improve work efficiency and ensure product quality.
