The thermos cup is a commonly used household item, it is indispensable whether at home or when traveling, especially for families with babies or in the cold winter. A cup of warm water warms the whole body. The buckle of the stainless steel vacuum flask, the bottom of the cup and even the circumference of the inner container need to be seamlessly welded. Laser welding can not only guarantee the overall welding effect, but the most important thing is to realize automatic welding management to ensure the exquisite and efficient welding gap.
Stainless steel vacuum flask can be seen everywhere in people’s daily life, but how is the high-grade stainless steel vacuum flask welded in the production and processing?
The stainless steel vacuum flask is made of double-layer stainless steel inside and outside. The inner tank and the outer shell are combined by welding technology, and then the air in the interlayer between the inner tank and the outer shell is drawn out by vacuum technology to achieve the effect of vacuum insulation. In order to ensure that residents have a good experience
Generally speaking, the thinner the cup material, the longer the heat preservation time, but the welded joint is not strong and the cup body is easy to be damaged and deformed, which affects the service life; therefore, it is recommended that the inner container is coated with a metal film and copper plating. The welding interface is made of metal materials that are not easily damaged! So as to realize the welding interface is dense and high in strength, and achieve the absolute tightness.
The key to outstanding achievement lies in whether it can bring forth the new and whether it can continue to improve. The welding field is no exception. Although the traditional welding methods and processes show good results, they also have many shortcomings. Especially for many small parts of the welding can not be perfect. As far as the welding of stainless steel vacuum insulated cups is concerned, the effect of traditional welding methods has some shortcomings. However, laser welding can make up for the shortcomings, realize ingenious continuous welding and pulse welding, and adopt non-contact welding methods for parts that are difficult to weld.
Traditional argon arc welding is based on the principle of ordinary arc welding. It uses argon gas to protect the metal welding material. Through high current, the welding material is melted into a liquid on the welded substrate to form a molten pool, so that the welded metal A welding technology that achieves metallurgical bonding with welding consumables. In this way, the welding seam of the stainless steel vacuum flask is large and unsightly. The welded product has an obvious protruding line at the cup mouth, which is easy to cause product deformation.
.
Because the welding and sealing requirements of the vacuum flask are very demanding, the traditional argon arc welding method is not suitable for welding stainless steel vacuum flasks, so we have to lift our laser welding machine.
The stainless steel vacuum flask laser welding machine is a kind of laser welding equipment that couples a high-energy laser beam into an optical fiber, and after long-distance transmission, it is collimated into parallel light by a collimator, and then focused on the workpiece to perform welding. It belongs to non-contact welding. There is no need to pressurize the product during the operation, so it will not deform the product.
Fiber laser welding machine can realize time and energy splitting, can process multiple beams at the same time, and implement flexible transmission non-contact welding for parts that are inaccessible to welding. It has greater flexibility and provides conditions for more precise welding.
The stainless steel vacuum flask is mainly made of stainless steel 304. Welding production must be strictly controlled for safety. Laser welding satisfies this point very well, and the operation is simple. The traditional welding method is relatively expensive when welding parts that are difficult to weld. Time-consuming. The laser welding method can improve efficiency and ensure quality reliability in the production process. Relatively speaking, this welding method can reduce costs and increase profits for enterprises.
According to relevant survey information, the stainless steel vacuum flasks in the domestic market are constantly being updated and are committed to launching more high-end products. Laser welding is used to achieve seamless welding and exquisite welding, to create a high-quality and beautiful stainless steel vacuum cup. It can be seen that the application field of laser welding will become larger and larger in the future development, especially it will become the key to promoting the development of stainless steel materials.
The biggest advantage of using laser welding is that it has high efficiency, exquisite weld seams, environmental protection, strong controllability in production, and a very low defect rate. Bring very considerable economic value to the enterprise.
At present, the stainless steel vacuum flask on the market is at a critical time for product upgrading and transformation. The price of the laser welding machine for professional welding of stainless steel vacuum flasks was very high in the past few years, but the price in the past two years has fallen to a price that the market can easily accept. It is understood that the stainless steel vacuum flask industry has a clear upward trend in laser welding manufacturers this year.
