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 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 holding 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 thickness of the inner tank is coated with metal film and copper plating. Weld metal materials that are not easily damaged for splicing! In this way, the welded joint is dense, high in strength, and absolute tightness is achieved.
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 materials. 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.
Since the welding and sealing requirements of the vacuum flask are very harsh, 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 the high-energy laser beam into the optical fiber, after long-distance transmission, it is collimated into parallel light by a collimator, and then focused on the workpiece for welding. There is no need to pressurize the product during the operation, so it will not deform the product. Laser welding
has exquisite welds, high speed, large depth, and small deformation, so it is widely used in the welding of vacuum flasks.
