Laser Welding Machine for Stainless Steel Vacuum Cup

Apr 23, 2020

The most basic requirement of the vacuum cup is sealing. The stainless steel cup is made of double stainless steel inside and outside. The laser welding machine uses welding technology to combine the tank and the shell together, and then uses vacuum technology to pump out the air in the inter-layer between the tank and the shell to achieve the effect of vacuum insulation. Only in this way can we ensure that residents have a good user experience! Generally speaking, the thinner the cup material, the lower the welding power. However, the welding interface is not firm, and the cup body is easy to be damaged and deformed, which affects the service life; therefore, it is recommended that the outer layer of the inner tank be coated with metal film and copper plating with the same thickness, and the welding interface is not easy to be damaged! So as to realize the dense and high strength of the welding interface and achieve absolute sealing.

Generally speaking, the thinner the cup material is, the longer the holding time is, but the welding interface is not firm, and the cup body is easy to be damaged and deformed, affecting the service life; therefore, it is recommended that the outer layer of the inner tank be coated with metal film and copper plating with the same thickness, and the welding interface is not easy to be damaged! So as to realize the dense and high strength of the welding interface and achieve absolute sealing.

The traditional argon arc welding is based on the principle of ordinary arc welding, which uses argon to protect the metal welding materials, and melts the welding materials into the liquid state on the base material to be welded by the high current to form a molten pool, so that the metal to be welded and the welding material can reach the metallurgical combination. In this way, the welding seam of the stainless steel vacuum cup is large and unsightly. There is an obvious protruding line at the mouth of the welding product, which is easy to cause product deformation.

Due to the strict requirements of sealing and welding of the vacuum cup, the traditional argon arc welding method is not suitable for the welding stainless steel heat preservation cup, so we have to come to the laser welding machine.

Stainless steel vacuum cup laser welding machine is a kind of laser welding equipment, which couples high-energy laser beam into the optical fiber, after long-distance transmission, collimated to parallel light through a collimator, and then focuses on the workpiece for welding. It belongs to non-contact welding, and the operation process does not need to pressurize the product, so it will not cause deformation to the product. Laser welding is widely used in the welding of vacuum cup because of its exquisite weld, high speed, large depth, and small deformation.

With the maturity of laser technology and the improvement of laser welding technology, a great breakthrough has been made in the welding of stainless steel vacuum cup. From traditional argon arc welding to laser welding, laser welding is favored by the majority of customers because of small surface deformation, dense solder joints, and no need for more post-treatment. KINGS laser is one of the early batch of laser welding machine equipment enterprises, with more than ten years of R & D and production experience, in technology and integration leading peer enterprises. Since its establishment, the company always pays attention to the research and development of laser technology and the development needs of customers, and is committed to providing perfect material processing solutions for each enterprise.
