Why heat preservation of stainless steel vacuum cup is effective? Just look at its laser welding process!

Vacuum cups are generally made of double-layer stainless steel inside and outside. A very critical step in the production process is welding. The mouth, bottom, and inner container of the vacuum flask need to be manufactured by laser welding machine welding technology.

 

Traditional argon arc welding uses argon gas to protect the metal welding consumables on the basis of ordinary arc welding. The welding consumables are melted into liquid form on the welded substrate through high current to form a molten pool, so that the welded metal and welding technology in which welding materials achieve metallurgical bonding. However, this method of welding stainless steel vacuum flask has large weld seams and is not beautiful, and there are many small problems in the details that cannot be perfectly welded. Laser welding can solve this problem well.

 

The laser welding machine radiates a high-intensity laser beam to the surface of the metal. Through the interaction between the laser and the metal, the metal absorbs the laser and converts it into heat, so that the metal is melted and then cooled and crystallized to form a weld, so that the weld is dense and the insulation cup can reach a good sealing effect.

 

The high-precision laser welding machine has exquisite welding seams, which can effectively avoid the problem of protruding lines after welding, and make the body of the vacuum cup smooth and delicate. The non-contact laser processing does not need to pressurize the product during the operation process, and there will be no deformation of the vacuum flask, and the yield rate is high. The laser welding machine does not require other consumables besides electric energy, does not cause harmful substances to the environment and the human body, and is easy to operate. It is an indispensable tool for manufacturers of vacuum flasks.
